Disconnect the inverter from the utility grid and the PV array, and reconnect it after LED turns off. If this fault is still being displayed, further assistance is needed.
What to do if Hypontech HPT-30K Inverter shows Ground fault circuit interrupter (GFCI) sensor error?
Disconnect the inverter from the utility grid and the PV array, and reconnect it after LED turns off. If this fault is still being displayed, further assistance is needed.
What to do if N and PE voltage exceeds permitted range on Hypontech Inverter?
Check if the inverter is securely grounded.
What causes the Hypontech HPT-30K Inverter grid frequency to exceed the permissible range?
The grid frequency exceeding the permissible range in your Hypontech Inverter is due to the grid frequency exceeding safety regulations. If it happens occasionally, it belongs to the short-time abnormality of the power grid, the inverter will return to normal operation after detecting the normal power grid. In case of frequent occurrence but automatic recovery, please confirm if the grid voltage is outside the permissible range due to local grid conditions, try to modify the values of the monitored operational limits after informing the electric utility company first. If it cannot be recovered for a long time, please confirm: whether the AC circuit breaker is disconnected, whether the AC terminal is in good connection, whether the power supply line is normal, whether the safety regulation ...
