  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.
