What to do for under grid voltage on SOLIS Inverter?
If your SOLIS Inverter is showing under grid voltage, use the user define function to adjust the protection limit if your electrical company allows it.
How to fix over grid voltage on SOLIS S5 Inverter?
If the SOLIS Inverter indicates over grid voltage, it could be that the resistance of the AC cable is too high. Try changing to a larger size grid cable. You might also adjust the protection limit if your electrical company allows it.
What to do if SOLIS Inverter has no power on LCD?
If the SOLIS Inverter LCD shows no power, first check the PV input connections. Then, verify the DC input voltage is adequate (single phase >120V, three phase >350V). Finally, check if the PV+/- is reversed.
Why my SOLIS Inverter 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.
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.
What to do if SOLIS Inverter 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 S5 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.
How to fix a NO-GRID error on a SOLIS S5 Inverter?
If your SOLIS Inverter displays a NO-GRID error, it means the inverter isn't detecting the grid. To troubleshoot, with the DC switch OFF, check the AC voltage at the inverter test points (L-L, L-GND). Also, check the LCD reading, as there may be a bad measurement circuit. With the DC switch ON, check the grid standard. If the issue persists, replace the inverter.
