How to check Iso Fault on Sofar solar HYD 5KTL-3PH Inverter?
To address an Iso Fault on your Sofar solar inverter, check the insulation resistance between the photovoltaic array and ground. If there is a short circuit, repair the fault promptly.
What does RemoteDerating mean on a Sofar solar Inverter?
RemoteDerating on your Sofar solar inverter indicates that the inverter is undergoing remote load reduction.
What to do if Sofar solar HYD 5KTL-3PH Inverter displays BMS OVP error?
If your Sofar solar inverter shows a BMS OVP error, close the inverter and lithium battery, wait 5 minutes, and then reopen both. Check if the problem is resolved. If the issue persists, it may indicate an internal failure of the lithium battery, and you should contact technical support.
Why Sofar solar HYD 5KTL-3PH shows OverTempDerating?
The OverTempDerating error on your Sofar solar inverter indicates it's overheating. To resolve this, ensure the inverter is installed in a cool, well-ventilated area away from direct sunlight. Also, verify that the inverter is mounted vertically and that the ambient temperature is below the inverter's temperature limit.
What to do if Sofar solar HYD 5KTL-3PH Inverter displays TempFault_Bat error?
If your Sofar solar inverter displays a TempFault_Bat error, ensure that the battery NTC cable is properly connected for Inner BMS battery. Also, make sure the inverter is installed where there is no direct sunlight, in a cool and well-ventilated place. Ensure the inverter is installed vertically and the ambient temperature is below the inverter temperature limit.
What to do if Sofar solar Inverter shows Grid OVP?
If the Grid OVP alarm occurs occasionally, the inverter will automatically return to normal operation when the electric grid returns to normal. However, if the alarm occurs frequently, verify that the grid voltage/frequency is within the acceptable range. If it is, inspect the AC circuit breaker and AC wiring of the inverter. If the grid voltage/frequency is outside the acceptable range and the AC wiring is correct, but the alarm persists, contact technical support to adjust the grid over-voltage, under-voltage, over-frequency, and under-frequency protection points after getting approval from the local electrical grid operator. The possible cause is that the electric grid is abnormal occasionally.
