More information about the GPIO settings can be found on page: Section 7.5

Input description

On the COMCAM Stuurbox there are multiple inputs required like IP addresses, IP address ranges and names. The steps below will explain how to use the buttons to insert characters.

Input options

Use the buttons on the COMCAM Stuurbox to select one of the four input options related to the position of the pressed button.

For example: the UP button selects and highlight the numeric input.

Select characters

When an input option is selected, use the UP and DOWN buttons to navigate and select a character or pre-defined value like and IP-address. Press the OK button or wait 3 seconds to confirm the selected character or value. Characters now appear in the input field as shown below.

Remove characters

While one of the input option is selected, press the BACK button to remove the last character or hold the OK button to clear all input.

Uppercase

It is possible to use uppercase characters. Hold the UP button to activate uppercase characters, and hold it again to switch back.

Configuration settings

On the “Config settings” page the basic system settings are done. The following configuration item are found:

• Apply settings
• Inverters
• Meters
• EV Chargers
• Auxiliaries
• Grid settings
• Grid voltage control
• Active power control
• Arc detection
• GPIO control

Apply settings

All settings in the config menu can be changed without directly effecting the current function of the COMCAM Stuurbox. When settings are changed, the changes must by applied using this menu. Applying the settings can be done selecting one of multiple strategies. Each strategy has predefined controllers and certain required settings to be set. After applying a new strategy the system will check all requirements and only if all requirements for the strategy are met, the new strategy is applied.

Activate config

This configuration will activate all settings for a selected strategy. Changed settings are stored, but not applied until the wanted strategy is selected and correctly applied. If a faulty configuration is found, the selected strategy returns an error, and the system function is not changed. Only if the selected strategy is correctly configured, the new configuration is applied and the old configured strategy is replaced by the new one.

Select strategy

To activate all settings, a strategy needs to be selected. The current implemented strategies are:

Zonbalans

Zonbalans will provide the stand-alone strategy using a grid meter, inverters and a pyrano sensor.

The maximum configured grid return power is used as maximum power. Until a measured radiation of 650 \(\frac{W}{m^2}\) the export limit is the configured grid return power. Between a measured radiation of 650 \(\frac{W}{m^2}\) and 975 \(\frac{W}{m^2}\) the export limit is linearly reduced from the configured grid return power to 0 kW. Therefore, at a measured radiation of >=975 \(\frac{W}{m^2}\) the export limit is 0 kW.

During the activation of the Zonbalans strategy, the total installed inverter power is requested. This is the sum of the AC output power of all connected inverters. This value is used for correct control of the power. For correct functioning of the Zonbalans strategy, please make sure the inverter power is correctly entered.

When activating the Zonbalans strategy all other control functions, like controlling GPIO, EV-chargers, battery converters etc. will be disabled.

The COMCAM Stuurbox is able to check the validity of the measured solar radiation, using the actual measured solar radiation and the actual solar power, combing both values using the total PV power configured in the inverter groups. When the generated solar power becomes larger than could be possible with the actual radiation and configured PV power, an error is triggered and the export limit is fixed to 0kW. The error can be recovered in the Zonbalans menu.

When the error is triggered it could indicate a dirty or not correctly functional radiation sensor and therefore wrong Zonbalans limits. If needed the check can be disabled while the Zonbalans strategy is applied.

Arc detection

Arc detection will only provide the arc detection functionality using an external arc detection. This strategy will not implement any export or import limiter. This allows for easy and fast arc detection integration in existing systems.

General

General will provide all required controllers, except for the countering controller. This strategy uses the entered solar power per group and grid export limits to create (if required) an export controller. At least one grid meter is required to do so.

Inverter configuration

This configuration allows the user to configure the connected inverters (if any). multiple groups can be made, where each group connects to the same type of meters, through the same physical interface.

Inverter groups

The “Inverter groups” page will show all existing inverter groups. There is one pre-set group called “New 1” that isn’t configured yet, this group is automatically added by removing your last existing group.

It is possible to add more groups, rename the existing groups, duplicate a specific group or delete one group. Select a group and hold the OK button to trigger this options.

Note

To add more than 15 inverters, a licence is needed, inverter ranges in different groups will be counted together as single inverters.

Configure inverter group

The following inputs are required to configure a group of inverter(s):

• Inverter connection
• Address range
• Inverter type
• Inverter IP address
• Inverter TCP port
• Strings per inverter
• Total number of solar panels
• Peak power per panel

When the inverter has battery support, the following extra fields are required:

• Battery energy capacity (Capacity of battery, should be the same for all batteries in the group), used for weighted SoC average.
• Maximum active battery power
• Set charge prio
• Set discharge prio
• Minimum SOC (State of Charge)
• Maximum SOC
• Minimum SoC for remote control

Inverter slave addresses

Insert the address range of the to be configured inverter(s). It is possible to separate addresses with the use of “,” or to define a range with the use of “-”. For example: The input “1,2,4-10” will set a address range from 1 to 10 except 3.

Note

An address may only occur once per RTU port. Meters and inverters could be connected to the same RTU port, as long as baudrate settings are identical and each connected slave has a unique address.

Inverter IP

Insert the IP address of the to be configured inverter(s). For example: “192.168.0.125”.

It is possible to define multiple addresses in the address range and only one IP address if all addresses can be reached through the same TCP/IP slave.

When the slaves are all reachable at the same address but on different IPs, it is possible to enter only one address and a range of IP addresses.

If each address has its own TCP/IP slave and a dedicated IP address, an IP range can be entered. To enter a range, the first IP address is entered followed by a ‘,’ or a ‘-’ and the last octet of the last IP address.

For example, if the address range is set to 1-4 (or 1, 2, 3, 4) and each address has a dedicated IP address, the IP input could be 192.168.0.10-13 (or 192.168.0.10, 11, 12, 13). The COMCAM Stuurbox will then translate this into the following IP addresses: 192.168.0.10, 192.168.0.11, 192.168.0.12, and 192.168.0.13.

Note

It should be noted that when multiple IP addresses are defined, the number of defined addresses must be one or be equal to the number of defined IP addresses. Failure to meet this criteria will result in an error when the settings are applied.

Note

Inverter IP will only be asked when the inverter connection type is TCP/IP.

Inverter TCP port

Insert the TCP port of the to be configured inverter(s). For example: “502”

Note

Inverter port will only be asked when the inverter connection type is TCP/IP.

Strings/MPPT per inverter

Insert the number of individual string or MPPT data which should be read for every inverter connected to the group. Basically the number of individually monitored strings or MPPTs per inverter is entered here.

Installed solar panels

Enter the total number of solar panels installed for this group of inverter(s).

Peak power per panel

Enter the peak power per panel for the installed solar panels. The total solar power (Installed solar panels * Peak power per panel) is used to calculate the required export limit controllers. If different panels are used, make sure the total entered power (Installed solar panels * Peak power per panel) is correct.

Enable active power control

If this setting is disabled the inverter is not controlled on active power. If needed some inverter groups can be excluded from the power control, while other groups have the control enabled.

Warning

The system controlled by the COMCAM Stuurbox should accept the control signal. To make this work, the external logger should be configured correctly. Active power control from the external logger should be disabled and the logger should accept external power control commands.

Maximum active battery power

This setting is only shown when a inverter with battery support is selected. The maximum active power of the battery can be entered. The gateway will limit the battery power setpoint to the configured value. The charge and discharge setpoints send to the battery will not exceed this value. The limit is applied per controlled battery. If multiple batteries are controlled per group, the limit is given per battery.

Battery energy capacity

The capacity of each battery. This capacity is used for the weighed SoC calculation. If multiple batteries are controlled within one group, the value is given per battery.

Set charge prio

Set the charge priority of the battery. When the priority is given free and the battery is allowed to charge, a charge setpoint is given to the battery. The charge priority should be lower (higher number) than the discharge priority.

Set discharge prio

Set the discharge priority of the battery. When the priority is not free yet, the discharge power will be maximum. Therefore the discharge can be used as peak shaving option to prevent exceeding the grid limits. The discharge prio should be higher (lower number) than the charge priority.

Minimum SoC

Set the minimum allowed SoC (State of Charge). When the SoC is reached the battery power setpoint will not allow any further discharge. If a SoC lower than the minimum SoC is measured, the battery is automatically charged with the configured charge prio, until the minimum SoC is reached.

Maximum SoC

Set the maximum allowed SoC (State of Charge). When the SoC is reached the battery power setpoint will not allow any further charge.

Minimum SoC for remote control

Minimum SoC to which the battery can be discharged via remote control. This value should be equal to or higher than “Minimum SoC”. The difference is only used to compensate the grid import limit using the battery. When control generation is set to max via the public API or HUB the battery will discharge until this SoC is reached. When the battery is discharged due to grid limits which are remotely set (via public API or HUB), the discharge is not limited to this SoC.

Maximum SoC for non-solar charge

Maximum SoC for all charge actions, except negative grid power charge. The value should be equal or lower than “Maximum SoC”, the difference can only be charged when “Charge with negative grid power” is enabled and the grid power becomes negative.

Allow automatic charge

When this setting is enabled, the battery will be given a charge setpoint as soon as the priority allows it. When it is disabled, the COMCAM Stuurbox will not automatically charge the battery, only if the consumption is set to maximum (or Charge battery with grid return power is enabled).

Meter configuration

This configuration allows the user to configure the connected meters (if any). multiple groups can be made, where each group connects to the same type of meters, through the same physical interface.

Note

Make sure the meter active power orientation is in the right convention used within the COMCAM Stuurbox.

A positive active power is always interpreted as a consumed power, while a negative active power is interpreted as a returned power.

Warning

When peakshaving for PV generation is active, the active power orientation for the grid meter should be correct. The COMCAM Stuurbox is only limiting (on grid power or grid current) the connected inverters when the measured grid power is negative (returning power to the grid).

Meter groups

The “Meter groups” page will show all existing meter groups. There is one pre-set group called “New 1” that isn’t configured yet, this group is automatically added by removing your last existing group.

It is possible to add more groups, rename the existing groups, duplicate a specific group or delete one group. Select a group and hold the OK button to trigger this options.

Note

To add more than 15 meters, a license is needed, meter ranges in different groups will be counted together as single meters.

Configure meter group

The following inputs are required to configure a group of meter(s).

• Meter connection
• Address range
• Meter type
• Meter location
• Meter IP address
• Meter TCP port

Note

Address range will only be asked when the selected connection type of the meter(s) is RTU or TCP/IP.

Note

Meter IP

Insert the IP address of the to be configured meter(s). For example: “192.168.0.125”.

It is possible to define multiple addresses in the address range and only one IP address if all addresses can be reached through the same TCP/IP slave.

When the slaves are all reachable at the same address but on different IPs, it is possible to enter only one address and a range of IP addresses.

If each address has its own TCP/IP slave and a dedicated IP address, an IP range can be entered. To enter a range, the first IP address is entered followed by a ‘,’ or a ‘-’ and the last octet of the last IP address.

For example, if the address range is set to 1-4 (or 1, 2, 3, 4) and each address has a dedicated IP address, the IP input could be 192.168.0.10-13 (or 192.168.0.10, 11, 12, 13). The COMCAM Stuurbox will then translate this into the following IP addresses: 192.168.0.10, 192.168.0.11, 192.168.0.12, and 192.168.0.13.

Note

It should be noted that when multiple IP addresses are defined, the number of defined addresses must be one or be equal to the number of defined IP addresses. Failure to meet this criteria will result in an error when the settings are applied.

Note

Meter(s) IP will only be asked when the meter(s) connection type is TCP/IP.

Meter TCP port

Insert the port of the to be configured meter(s). For example: “502”

Note

Meter(s) port will only be asked when the meter(s) connection type is TCP/IP.

Meter location

Select here the meter(s) location of the to be configures meter(s), options are:

• Grid meter
• Load meter
• MLOEA-PAP
• MLOEA-SAP

Note

All meters configured as Grid meter should measure the same power. Multiple meters configured as Grid meter can be used as redundant measurement. If the measurement in one of the Grid meters is not corresponding with the measurements of the other, an error is raised and inverters are safely reduced to there safe power. This to prevent the export limit to exceed the configured limit.

Note

The Grid meter is used for control. To make sure the readout speed is not limited it is good practice to connect the Grid meter to a single port (RTU-A, RTU-B, RTU-C or TCP), and connect other devices to other ports. On this way the maximum readout speed is reached.

Note

For a MLOEA grid connection, both meters (MLOEA-PAP and MLOEA-SAP) need to be configured. The COMCAM Stuurbox will calculate the actual grid power and currents by combining both meters. Setting up only one of the two MLOEA meters result in a incorrect configuration.

Split solar/grid

Available when load meter is selected. Enabling this function will create two new meter registers, one for the energy directly consumed out of Solar energy and one register for the energy directly consumed out of grid energy. Two possible system configurations are possible.

• System with at least one grid meter and 1 or more load meters. The system will count all energy sourced by the grid meter as grid energy, all energy consumed but not sourced by the grid meter is counted as solar energy.

• System without a grid meter, in this case the power delivered by the connected solar inverters is used to calculate the solar energy. All other energy is counted as grid energy.

Note

To activate the split solar/grid energy meters at least one grid meter or one solar inverter should be connected. An error is raised during setting activation when both (grid meter and solar inverter) are not configured.

Override scaling factor (only for P1 meter)

The values read from the P1 meter can be scaled with a fixed scaling factor. The default scaling factor is 1x. If “yes” is selected, the user will be prompted to enter the scale factor.

Warning

Only change the default scaling factor if this is required by the grid operator. Selecting the wrong value will result in inaccurate energy measurement and improper control of active power!

Scale factor

This option is only available when “Override scaling factor” is set to “yes.” Select the scale factor:

• 1x (default)
• 200x
• 500x
• 2000x

Warning

Ensure to verify the scaling factor. Selecting the wrong value will result in inaccurate energy measurement and improper control of active power!

EV Chargers

This configuration will define all EV Charger(s) settings. (INTRO ABOUT EV CHARGERS)

EV Charger groups

The ‘EV Charger groups’ page will show all existing EV Charger groups. There is one pre-set group called ‘New group’ that isn’t configured yet, this group is automatically added by removing your last existing group.

It is possible to add more groups, rename the existing groups, duplicate a specific group or delete one group. Select a group and hold the OK button to trigger this options.

Note

Enter the slaves for the EV Charger(s). It is possible to separate slaves with the use of “,” or to define a range with the use of “-”. For example: The input “1,2,4-10” will set a the slaves 1 to 10 except 3.

Note

EV Charger(s) slave addresses will only be asked when the EV Charger(s) connection type is RTU-A, RTU-B, RTU-C or TCP/IP.

Min. charge current

Select the minimum charge current which is send to the device during import limitation. If the current is more than 0, the charger will not stop charging, even if the configured import limit is exceeded. The configured minimum charge current should be equal to or less than Max. charge current.

Max. charge current

Select the maximum charge current which is send to the device when there is no import limit. The configured minimum charge current should be equal to or less than Max. charge current.

Set prio

The priority for the EV charger current can be set. When power for consumption is available, the COMCAM Stuurbox will increase loads depending on their priority. A high priority (low number) is released first and reduced last. Therefore, an EV charger with priority 1 always has the “Min. charge current” available, when the system limits allow it, the current is released to “Max. charge current”. Any other EV charger with priority 2 or higher has the “Min. charge current” available, and will only increase the current if system limits allow it, and all chargers with a lower priority number are fully released.

EV Charger IP

Insert the IP address of the to be configured EV Charger(s). For example: “192.168.0.125”.

It is possible to define multiple addresses in the address range and only one IP address if all addresses can be reached through the same TCP/IP slave.

Enter the slaves for the Auxiliaries. It is possible to separate slaves with the use of “,” or to define a range with the use of “-”. For example: The input “1,2,4-10” will set a the slaves 1 to 10 except 3.

Note

An address may only occur once per RTU port. Slaves of different types could be connected to the same RTU port, as long as baudrate settings are identical and each connected slave has a unique address.

Auxiliaries type

Select the connection type of the to be configured Auxiliaries the options are:

• IO TM-P4A4 (Modbus GPIO module)
• Kipp&Zonen SMP3-A (Pyrano sensor)
• Huawei SL pyrano (Pyrano sensor connected to the Huawei smartlogger)

Note

Auxiliaries IP

Insert the IP address of the to be configured Auxiliaries. For example: “192.168.0.125”.

It is possible to define multiple addresses in the address range and only one IP address if all addresses can be reached through the same TCP/IP slave.

When the slaves are all reachable at the same address but on different IPs, it is possible to enter only one address and a range of IP addresses.

If each address has its own TCP/IP slave and a dedicated IP address, an IP range can be entered. To enter a range, the first IP address is entered followed by a ‘,’ or a ‘-’ and the last octet of the last IP address.

For example, if the address range is set to 1-4 (or 1, 2, 3, 4) and each address has a dedicated IP address, the IP input could be 192.168.0.10-13 (or 192.168.0.10, 11, 12, 13). The COMCAM Stuurbox will then translate this into the following IP addresses: 192.168.0.10, 192.168.0.11, 192.168.0.12, and 192.168.0.13.

Note

It should be noted that when multiple IP addresses are defined, the number of defined addresses must be one or be equal to the number of defined IP addresses. Failure to meet this criteria will result in an error when the settings are applied.

Note

Auxiliaries IP will only be asked when the Auxiliaries connection type is TCP/IP.

Auxiliaries port

Insert the port of the to be configured Auxiliaries. For example: “502”

Note

Auxiliaries port will only be asked when the Auxiliaries connection type is TCP/IP.

Grid settings

In this configuration power and current limits for the plant can be defined.

Grid settings configuration

The following inputs are required to configure the grid settings:

• Grid current max
• Grid + power max
• Grid - power max

Grid current max

Enter the maximum allowed grid current for this plant. For example, the mains connection is 3x250 A, fill-in 250.

Tip

This is typically the value of the main fuse.

Grid + power max

Enter the maximum active power which might be consumed from the grid. For example: 50 kW.

Grid - power max

Enter the maximum active power which might be exported to the grid. For example: 100 kW. The COMCAM Stuurbox will implement export limitation controllers for configured solar inverters if the configured solar power exceeds the configured limit.

Grid voltage control

The grid voltage control can be enabled to apply an active power controller in the COMCAM Stuurbox, regulating the measured grid voltage. The maximum line-neutral grid phase voltage is determined, if this voltage is larger than the configured maximum grid voltage, the inverter active power setpoint is reduced (Using a fixed PI controller). This will limit the active power and therefore lower the grid voltage.

Tip

The grid voltage measured by the inverter is likely to be higher than the voltage at the grid entrance or grid meter location. Hence, it is important to ensure that the maximum allowable grid voltage set in the inverter is higher than the configured maximum grid voltage in the COMCAM Stuurbox.

Warning

The P1 DSMR 4 protocol does not support phase voltage measurement. Therefore it is not possible to use grid voltage control when the grid meter is a P1 DSMR 4 energy meter.

Active power control

By default, the configured number and power of the solar panels, together with the configured maximum grid return power and maximum grid current let the COMCAM Stuurbox decide if an active power or current controller is required for the configuration. By default an plant control active power controller is also implemented. As user this default configuration can be altered, by changing the Active power control setting.

• Auto: (Default) depending on the configured limits an active power and/or current controller is implemented
• Force disable: all power controllers are disabled! Plant control, export limit control and grid voltage control is not possible. Be careful using this configuration!
• Force enable: enables the plant control, active power and grid current controller independent of the amount of solar power configured. Using this setting the maximum reduction value can be limited by the user.

Warning

Setting the “Force disable” option will disable all active power controllers. There will be no grid current, power or voltage control done by the COMCAM Stuurbox. Also power control via plant control is disabled! Therefore inverters will not be limited when EPEX price control is active.

Safety margin

The “Safety margin” is 0 by default. It sets a positive offset to the configured grid return power. An example: a plant is not allowed to return power to the grid (negative grid power), so the maximum grid return power is set to 0. Due to loads which are switched off, some energy will still be returned to the grid. To prevent this, a safety margin can be configured. The COMCAM Stuurbox will offset the control setpoint with the safety margin. If the grid return power is set to 0kW and the safety margin is set to 5kW, the COMCAM Stuurbox will limit PV and battery power in such way the grid power is tried to be 5kW. When a load of 4kW is suddenly switched off, the grid power will still be positive and the COMCAM Stuurbox will correct for it.

Warning

Only utilize the safety margin option in instances where there is a highly stringent return-to-grid policy. Utilizing the safety margin will lead to an increase in total grid power consumption and consequently, costs.

Low power limit

The “low power limit” is disabled by default. This function can be enabled if the maximum generated solar power should be continuously controlled (even when the grid power or current is not close to the limit). This function prevents large peaks when solar power suddenly increases but also increases the inverter ramp-up time. Enabling this option results in significantly lower peak powers. The total configured inverter power is required to correctly use this function. The function can’t correctly operate when not all inverters are active, if one of the inverters is not active, the function will temporary be disabled.

Tip

For systems with PV peak-shaving for a limited mains connection, it is advised to enable the low power limit option. This prevents high peak feeding currents which may trip the mains fuse.

Total PV inverter power

(This value is only required when Low power limit is enabled). The sum of the total nominal PV inverter power. Inverter which are only used as battery converter should not be included in the sum.

Maximum power limit

Setting the maximum power limit to less than 100% will consistently restrict the inverters maximum output power to the configured percentage. Consequently, the maximum output power of the inverters will never be attained, even if the grid current and grid negative power have not yet reached their limits yet.

For Auto and Force enable the following options are available to configure low power limit:

Allow PV for import limit

Default disabled. Enabling this function allows the PV limit controller to further increase PV power when the import limit is reached. Therefore the PV power could still be generated while the system in in MIN generation, only to prevent the import limit to be exceeded. PV is controlled with PRIO1, other priorities are processed first before PV power is increased.

Charge battery with grid return power

When this function is enabled, the battery charge power is increased when the mains active power becomes negative. Therefore the returned grid power could be used for charging the battery. It is advised to disable the “Allow automatic charge” option in the inverter group.

Arc detection

This configuration will define the external arc detection settings. By default external arc detection is disabled. Keep in mind, any GPIO used to connect to the external arc detection should by true when no arc is detected!

Arc detection configuration

The following inputs are required to complete Arc detection configuration:

• Input type
• Minimum PAC
• Inverter address

Input type

Select the input type for Arc detection, options are:

• Deactivate
• GPIO (use onboard GPIO for max 2 inverters)
• Ext. GPIO (use modbus GPIO modules for multiple external arc detections)
• Both (Use as well the internal GPIO as external GPIO modules)

Tip

The deactivate option will deactivate arc detection, even if the Arc detection strategy is selected. Arc detection is deactivated by default.

Minimum PAC

Enter the minimum PAC (Inverter AC power) required per inverter for an arc detection. If the AC power of the inverter is not at least as high as Minimum PAC, while a detection is done, the detection is neglected.

Inverter address

This menu is only visible if the “Both” option is selected. It allows the user to select the one or two inverter addresses controlled by the internal GPIO. The other addresses will be logically (from low to high) mapped to the external GPIO modules. For example, if 5 inverters are configured, 1,2,3,4,5 and only 2 external GPIO modules are configured and “Inverter address” is set to 3,4: The first GPIO modules is connected to inverter 1, the second GPIO module to inverter 2 and GPI1 is connected to inverter 3, GPI2 to 4. Inverter 5 has no arc detection connected. Setting the “Inverter address” to 1 in this situation connects inverter 1 to GPI1 and inverter 2 to external GPIO 1 and inverter 3 to external GPIO 2.

Connecting the external arc detection

When connecting the external arc detection please check the following items:

• Make sure the arc detection is not latched on detection.
• Make sure the GPIO of the COMCAM Stuurbox or input on the external GPIO are HIGH when no detection is done and LOW when a detection is done.
• Check the functionality of the external arc detection
• Check the functionality of the configured COMCAM Stuurbox, check if the correct inverter is turned-off when a detection is done.

GPIO control

Allows the user to add multiple rules for the onboard or external GPIO. Actions can be triggered depending on the GPI (General Purpose Input) state or states can trigger GPO (General Purpose Output). The COMCAM Stuurbox has two GPI and two GPO onboard. It is possible to configure 4 independent GROUP states, which can be linked to the digital output of external IO modules.

Each rule added to the list can only handle one state, for example the following setting: “IN1 is HIGH then set Min gen set to TRUE” Will limit the generation when input1 becomes HIGH. After input1 becomes LOW again, no new action is triggered, so the system will stay in Min gen. To return to normal operation when input1 is low again, the following rule should also be added: “IN1 is LOW then set Min gen set to FALSE”

It is possible to use the following variables to define triggers:

• contr. gen. (Control Generation) which is the generation state which can be remotely set to MIN, NOM or MAX (default NOM)
• contr. cons. (Control Consumption) which is de consumption state which can be remotely set to MIN, NOM or MAX (default NOM)
• Psolar (System Solar power) which is the actual solar power (sum of solar power of all inverters), value is set in kW
• Pgrid (System grid power) which is the grid meter active power, value is set in kW
• Reduction which is the actual solar inverter limit value, 0 means solar is reduced to 0% of nominal, and 100 means solar is unlimited
• Battery SoC which is the (weighted) average of the connected battery SoC values, value is set in %
• Summed load meters which is the sum of the active power of all the load meters, value is set in kW
• Pbattery the total battery power in the system, value is set in kW
• PRIO the actual load prio 0-10, where 0 means all loads off and generate to reach the import limit, value is set between 0 and 10

As example, when GPO1 needs to be enabled when the grid power is -10kW and disabled when the grid power is 0kW the following rule can be set:

Group: GPO1 ON (give the action a logic name) Select GPIO: GPO1 (the rule will control GPO1) Set to: TRUE (The rule will enable GPO1) When: Pgrid (select grid power) Opperator: < (When greater than) Value: value (select free value input) Set value: -10 (set the value to -10kW)

Group: GPO1 OFF (give the action a logic name) Select GPIO: GPO1 (the rule will control GPO1) Set to: FALSE (The rule will enable GPO1) When: Pgrid (select grid power) Opperator: > (When greater than) Value: value (select free value input) Set value: 0 (set the value to 0kW)

As example, when GPO1 needs to be enabled when control generation is set to MIN remotely:

Group: GPO1 ON (give the action a logic name) Select GPIO: GPO1 (the rule will control GPO1) Set to: TRUE (The rule will enable GPO1) When: contr. gen (Select control generation as this value is changed remotely) Opperator: == (Equal to) Value: min (MIN, to set GPO1 to true when contr. gen. is set to MIN)

Group: GPO1 OFF (give the action a logic name) Select GPIO: GPO1 (the rule will control GPO1) Set to: FALSE (The rule will disable GPO1) When: contr. gen (Select control generation as this value is changed remotely) Opperator: != (Not equal to) Value: min (MIN, to set GPO1 to false when contr. gen. is NOT set to MIN)

Tip

The activation and deactivation of a GPO or Group is always done in two separate actions. Multiple actions can be created which all enable or disable the GPO.
