•Check the wirings to see if the connection is ok. The conductors in the cables may have been damaged or cut.
•Check if the connector connection is ok. The connector may be broken or connected improperly.
•Check that there is not discrepancy between the real grid voltage and the voltage setting in the installation app.
•Check that the permissible current of the circuit breaker is 20A.
•Check if the cables are for outdoor usage.
•Check the size of the cables. If the size of the cables is smaller than 12AWG, the flowing current in cables may be limited and the voltage may rise.
