Disabling Battery Charging by PV System in Battery-Backup Operation Mode

Depending on the state of charge in terms of battery and PV generation, it can happen that the battery-backup grid is interrupted for a few seconds in battery-backup operation mode during load changes and then restarts again. To prevent this behavior, you must make the following settings.

The basic procedure for changing operating parameters is explained in another section ( > Changing Operating Parameters).

Procedure:

  1. Select the parameter Output power limitation of PV inverter and set it to Permanently derated.
  2. Set the parameter Upper limit for the charging state for derating of the PV inverters to 0.
