      If your Fronius Inverter's battery isn't charging or discharging, and the SOC indicated on the web interface doesn't match that of the battery, first check whether the battery is switched on. If it isn't, switch it on. If the battery is already on, disconnect the inverter on the DC side and isolate it from the grid on the AC side. Wait 5 minutes, then reconnect the inverter on both the DC and AC sides. If the issue persists, notify Customer Services.

      If the battery is active, the state of charge (SOC) is more than 90%, and the red LED is flashing on your Fronius Inverter, it indicates a battery charging error. To resolve this, disconnect the inverter on the DC side and isolate it from the grid on the AC side. Wait 30 minutes, then reconnect the inverter on both the DC and AC sides. If the error continues, notify Customer Services.

      If the battery switches off with a SOC (state of charge) of 0% in your Fronius Inverter, it may be due to a communication error. Disconnect the inverter on the DC side and isolate it from the grid on the AC side. Wait 5 minutes and then reconnect the inverter on both the DC and AC sides. If this does not resolve the error, notify Customer Services.
