Why does my Sofar solar HYD 20KTL-3PH Inverter show a BMSCommunicationFault?
A BMSCommunicationFault on your Sofar solar inverter may occur if your battery is not compatible with the inverter. CAN communication is recommended. Check the communication line or port of the battery and inverter for faults.
What to do if Sofar solar HYD 20KTL-3PH 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.
What causes PVOVP error on Sofar solar HYD 20KTL-3PH and how to fix it?
The PVOVP error on your Sofar solar inverter indicates that the PV series voltage (Voc) is higher than the maximum input voltage of the inverter. To resolve this, check whether the PV series voltage is indeed too high. If it is, adjust the number of PV modules in series to reduce the PV series voltage, ensuring it fits within the input voltage range of the inverter. After making this correction, the inverter should automatically return to its normal state.
What to do if my Sofar solar HYD 20KTL-3PH Inverter shows GridOVP frequently?
If the GridOVP alarm occurs frequently on your Sofar solar inverter, first check if the grid voltage or frequency is within the acceptable range. If the voltage or frequency is not within the acceptable range and the AC wiring is correct, contact technical support to change the grid over-voltage, under-voltage, over-frequency, and under-frequency protection points after getting approval from the local electrical grid operator. However, if the alarm occurs occasionally, the inverter should automatically return to normal when the electric grid returns to normal.
What to do if Sofar solar Inverter displays ConfigError?
If your Sofar solar inverter displays a ConfigError, check the input mode settings (parallel/independent mode) for the inverter. If the settings are incorrect, change the input mode accordingly.
How to check Iso Fault on Sofar solar HYD 20KTL-3PH?
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 20KTL-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 20KTL-3PH Inverter 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 20KTL-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.
