Victron

Supported Devices

[!DANGER]

Important

If you already have your PV or other devices connected to the Victron system make sure not to add them again to the Sofar EMS. This can cause double measurements.

Wiring

For correct ethernet wiring: Follow the the guidelines for ethernet wiring.

Configuration

1. Modbus TCP must be enabled.

In the settings of the inverter:

1. Go to "Settings"
2. Go to "Services"
3. Go to "Modbus TCP"
4. Select "Enable Modbus/TCP."

2. The ESS must be in a mode that allows steering. In the inverter settings, go to:

1. Go to "Settings"
2. Go to "ESS"
3. Select mode "Optimized (without BatteryLife)"

[!DANGER]

Important

IF THIS MODE IS CHANGED, THE SYSTEM WILL NOT WORK PROPERLY!

3. Disable scheduled loading

1. Go to "Settings"
2. Go to "ESS"
3. Go to "Scheduled charge levels"
4. Disable all scheduled charge levels

4. Activate switch

The switch at the bottom of the inverter must be in position 1 to accept the control.

Troubleshooting

If your inverter still is not working properly, please check the following:

1. Dynamic ESS must be disabled.
2. Are your grid limits set correctly?
3. Are your groups set correctly in the controller? (See example below)
4. If the battery is oscillating, set the scheduler run time to 5s minimum in the advanced settings.

If you experience problems with the control of the inverter, please follow these steps:

1. Before following these steps make sure to remove the Victron inverter from the Sofar EMS controller so that the controller doesn't interfere with the testing.
2. Now go to the Victron interface. Under the "Settings" tab, go to "System Setup".

3. Go to "ESS".

4. Press "Grid setpoint".

5. Set the grid setpoint to a certain value so that the battery will start charging or discharging.

6. Validate on the overview page that the battery is charging or discharging.

7. If there is no response to the setpoint then this indicates there is an issue with the Victron inverter, rather than the Sofar EMS controller."
