How to fix software version inconsistency on Sofar solar HYD 3K~6K-ES?
Contact SOFAR technical support to upgrade the software of your Sofar solar Inverter, because the software version between control board and com board is not consistent.
What to do if GFCI OCP fault occurs on Sofar solar HYD 3K~6K-ES Inverter?
If a GFCI OCP fault occurs occasionally on your Sofar solar Inverter, it might be due to temporary abnormalities in the external circuits. The HYD-ES inverter should automatically return to normal operation once the issue is resolved. However, if the fault persists, examine the insulation resistance between the PV array and earth (ground), and also inspect the PV cables for any insulation problems. The cause is that the GFCI sampling value between the master DSP and slave DSP is not consistent.
Why does my Sofar solar HYD 3K~6K-ES show a PVOVP error?
If your Sofar solar Inverter displays a PVOVP error, it means the PV voltage is too high. This can happen if too many PV modules are connected in series, causing the PV string voltage (Voc) to exceed the inverter's maximum input voltage. To fix this, reduce the number of PV modules connected in series to lower the PV string voltage within the acceptable input range for your HYD-ES inverter. After making these adjustments, the inverter should automatically return to normal operation.
What causes GridOVP alarm on Sofar solar HYD 3K~6K-ES?
If your Sofar solar Inverter displays a GridOVP alarm, it indicates that the grid voltage is too high. If this alarm occurs occasionally, it's likely due to temporary issues with the electrical grid. The HYD-ES inverter should automatically return to normal operation when the grid voltage stabilizes.
What to do if Sofar solar Inverter shows Unrecover OCPInstant?
If your Sofar solar Inverter is showing an Unrecover OCPInstant error, it indicates that the grid current is too high, causing an unrecoverable fault. To attempt a fix, switch OFF the HYD-ES inverter, wait for 5 minutes, and then switch it back ON. If the problem persists after this, contact SOFAR technical support.
Why does my Sofar solar HYD 3K~6K-ES show a BatOVP alarm?
If your Sofar solar Inverter displays a BatOVP alarm, signaling that the battery voltage is too high. If this happens occasionally, wait to see if the problem resolves itself. However, if the alarm occurs frequently, verify that the battery overvoltage setting aligns with the battery's specifications.
How to fix OverTemp Fault_BAT on Sofar solar HYD 3K~6K-ES Inverter?
If your Sofar solar Inverter shows an OverTemp Fault_BAT, it means the battery temperature is too high. Ensure the HYD-ES inverter is installed in a location without direct sunlight and is well-ventilated. Also, verify that the inverter is installed vertically and the ambient temperature is below the inverter's upper temperature limit.
What does Over FreqDerating mean on Sofar solar HYD 3K~6K-ES?
If your Sofar solar Inverter displays an Over FreqDerating error, it indicates that the AC frequency is too high. Ensure that the grid frequency is within the acceptable range.
What causes PvIsoFault on Sofar solar Inverter?
If your Sofar solar Inverter displays a PvIsoFault, it indicates that the insulation resistance is too low. Check the insulation resistance between the PV array and earth (ground). If there is a short circuit, rectify the fault.
How to resolve HwBuckBoostOCP error on Sofar solar HYD 3K~6K-ES Inverter?
If your Sofar solar Inverter displays a HwBuckBoostOCP error, check that the CT connection is secure and that the installation direction is correct.
