Important

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

Wiring​

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

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)"
Important

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.
Groups example

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 SmartgridOne 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".
Groups example
  1. Go to "ESS".
Groups example
  1. Press "Grid setpoint".
Groups example
  1. Set the grid setpoint to a certain value so that the battery will start charging or discharging.
Groups example
  1. Validate on the overview page that the battery is charging or discharging.
Groups example
  1. If there is no response to the setpoint then this indicates there is an issue with the Victron inverter, rather than the SmartgridOne controller."
