Analysis: Inverter internal AC current output over range
1. Check if the solar panel be configured too many. Check if total installed solar panel capacity is too high.
2. Check if there is a short-circuit in AC wire connection or in inverter AC terminal.
3. Restart inverter (disconnect DC&AC switch, wait for 5 mins, then turn it on), observe if it can return to normal running.
4. Observe if the grid Voltage is fluctuating too much.
