To Next PageTo Next PageWhat should I check if my SOLIS Inverter has no grid voltage?
If your SOLIS Inverter indicates no grid voltage, first check the connections and the grid switch. Then, check the grid voltage inside the inverter terminal.
What to do if my SOLIS S5-GR3P20K shows 'Over Temperature'?
If your SOLIS Inverter is showing an 'Over Temperature' error, check the ventilation around the inverter to ensure it's not obstructed. Also, verify whether the inverter is exposed to direct sunlight during hot weather.
What to do if SOLIS S5-GR3P20K LCD has no power?
If your SOLIS Inverter's LCD has no power, check the PV input connections. Also, verify the DC input voltage (single phase >120V, three phase >350V) and ensure that the PV+/- connections are not reversed.
What to do if my SOLIS Inverter shows 'Over DC voltage'?
If your SOLIS Inverter is showing an 'Over DC voltage' error, reduce the number of modules in series.
Why my SOLIS S5-GR3P20K can not start-up?
If your SOLIS Inverter cannot start up, check if the connectors on the main board or power board are securely fixed. Also, check if the DSP connector to the power board is properly connected.
