Solar Panel Inverter Troubleshooting

The charging light on the controller shouldn t be lit.

Solar panel inverter troubleshooting.

This can range from physically misconnecting them to incorrect programming of the inverters. If the inverter is showing an error message refer to the manual or search online to find out what it means. As the pv modules are connected in series one failing pv module will shut down the entire system. Check the output of the system on the inverter for at least one or two days to see if there is definitely no solar generation check if the solar circuit breaker has tripped.

If the green light lights up then this indicates the controller may be damaged. Drop in production and or an increase in utility bills our thorough diagnosis will spot any problems with that prevent optimum output of you solar panel system. Half of inverter problems are actually due to the solar array having a faulty panel or cable and the inverter detecting this according to bright green renewables managing director mark partridge.
