Input description

On the SolarGatewaySE 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 SolarGatewaySE to select one of the four input options relared 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
• Help

Apply settings

All settings in the config menu can be changed without direcly effecting the current function of the SolarGatewaySE. When settings are changed, the changes must by applied using this menu. Appying 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, a stratagy must be selected. Changed settings are stored, but not applied until the wanted strategy is selected and correctly applied. If a faulty configuration is found, the selected stratagy 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 strategie is replaced by the new one.

Select stratagy

To activate all settings, a stratagy needs to be selected. The current implented stratagies are:

Counteren

Counteren will provide the stand-alone counter controller using a grid meter, inverters and a pyrano sensor. The maximum configured return power is used as maximum power. Until a measured radiation of 500 \(\frac{W}{m^2}\) the export limit is the configured return power. Between a measured radiation of 500 \(\frac{W}{m^2}\) and 1000 \(\frac{W}{m^2}\) the export limit is linearly reduced from the configured return power to 0 kW. Therefore, at a measured radiation of >=1000 \(\frac{W}{m^2}\) the export limit is 0 kW.

During the activation of the Counteren stratagy, 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 Counteren stratagy, please make sure the inverter power is correctly entered.

The SolarGatewaySE 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 Counteren menu.

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

Arc detection

Arc detection will only provide the arc detection functionallity 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). Multipiple 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 automaticly 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

Note

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

Inverter connection

Select the connection type of the to be configured inverter(s)

The following connection types can be selected:

• RTU-A (X10)
• RTU-B (X11)
• RTU-C (X12)
• TCP/IP

Inverter slave addresses

Insert the address range of the to be configured inverter(s). It is possible to seperate 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 occures 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 type

Select here the type or brand of the to be configured inverter, in the image below ‘Goodwe’ is selected.

The following types can be selected:

• INVT
• Growatt-V1
• Growatt-V2
• Huawei V2
• Huawei V3
• SMA tripower
• SMA Sunspec
• SolarEdge
• Solax 3phase
• Sofar G1
• Sofar G2
• Sofar G3
• Delta Sunspec
• ABB Trio
• SAJ Plus series

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.

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 SolarGatewaySE 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 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.

Meter configuration

This configuration allows the user to configure the connected meters (if any). Multipiple 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 SolarGatewaySE.

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 SolarGatewaySE 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 automaticly 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 licence 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 address and TCP port will only be asked when the selected connection type of the meter(s) is TCP/IP.

Meter connection

Select the connection type of the to be configured meter(s) the options are:

• RTU-A (X10)
• RTU-B (X11)
• RTU-C (X12)
• P1
• TCP/IP

Note

When meter(s) connection is P1, the only extra setting needed to complete are extra connected P1 meters and meter location.

Meter slave addresses

Insert the address range of the to be configured meter(s). It is possible to seperate 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 occures 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.

Meter type

Select here the type or brand of the to be configured inverter, in the image below ‘Goodwe’ is selected. The following type or brands are available to select:

• Eastron
• Socomec Diris
• Socomec Countis (No THD measurement)
• Janitza
• Hager EC
• Weidemuller EM610
• ABB B23/B24 (No THD measurement)
• Sneider NSX
• Sneider PM series

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.

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 SolarGatewaySE 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 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 measurments 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

For a MLOAE grid connection, both meters (MLOEA-PAP and MLOEA-SAP) need to be configured. The SolarGatewaySE 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

Availble 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 sysem 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.

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 SolarGatewaySE will impelemnt 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 SolarGatewaySE, 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 SolarGatewaySE.

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 SolarGatewaySE deside 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.

The “low power limit” is default disabled. This function can be enabled if the maximum generated solar power should be continiously 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. Enabeling 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.

• Auto: (Default) dependend 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 carefull using this configuration!
• Force enable: enables the plant control, active power and grid current controller independend of the amound of solar power configured. Using this setting the maximum reduction value can be limited by the user.

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:

Tip

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

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 SolarGatewaySE. Also power control via plant control is disabled! Therefore inverters will not be limited when EPEX price control is active.

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 deactive 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 SolarGatewaySE 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 SolarGatewaySE, 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 GPIO. Actions can be triggered dependend on the GPI (General Purpose Input) state or states can trigger GPO (General Purpose Output). The SolarGatewaySE has two GPI and two GPO.

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”
