What to do if SOLIS S5-GR3P13K 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.
How to fix over grid voltage on SOLIS S5-GR3P13K 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 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 reduce DC voltage on SOLIS Inverter?
If the SOLIS Inverter shows over DC voltage, reduce the number of modules in series.
What to do if SOLIS Inverter detects arc in DC circuit?
If the SOLIS Inverter detects an arc in the DC circuit, check the inverter connection for any signs of an arc and then restart the inverter.
What to do if SOLIS S5-GR3P13K shows over DC bus voltage?
If the SOLIS Inverter shows over DC bus voltage, check the inverter inductor connection and the driver connection.
How to resolve grid interference with SOLIS Inverter?
If the SOLIS Inverter is experiencing grid interference, try restarting the inverter. If the problem continues, consider changing the power board.
What to do if SOLIS S5-GR3P13K is internally damaged?
If the SOLIS Inverter is internally damaged, do not turn off the DC switches, as this will further damage the inverter. Wait for the solar irradiance to reduce and confirm the string current is less than 0.5A with a clip-on ammeter before turning off the DC switches. Note that damages due to wrong operations are not covered under warranty.
What to do for AFCI module self-detect fault in SOLIS Inverter?
If the SOLIS Inverter shows AFCI module self-detect fault, restart the inverter or contact a technician.
