Analysis: Inverter internal AC current output over range
Solution:
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.
