What does it mean if the GFCI sampling value is not consistent in Sofar HYD3000-ES?
If the fault occurs occasionally, the external circuits may be temporarily abnormal. The HYD-ES inverter should automatically return to normal after the fault is rectified. If the fault occurs frequently and lasts a long time, check the insulation resistance between the PV array and earth (ground), and also check the insulation conditions of PV cables.
What to do if Sofar HYD3000-ES Inverter shows battery voltage too high?
If the alarm occurs occasionally, wait a while to see if the problem resolves itself. If the alarm occurs frequently, check whether the battery overvoltage setting is inconsistent with the battery spec and contact SOFAR technical support.
Why is the PV voltage too high on my Sofar HYD3000-ES?
Too many PV modules may be series connected in a PV string. Check if the voltage (Voc) of the PV string is higher than the maximum input voltage of the HYD-ES inverter. If it is, adjust the number of series-connected PV modules to decrease the voltage of the PV string to fit within the input voltage range of the HYD-ES inverter.
How to fix low insulation resistance on Sofar HYD3000-ES Inverter?
Check the insulation resistance between the PV array and earth (ground). If a short circuit is found, rectify the fault.
What causes unbalanced input current on Sofar HYD-ES Inverter?
Check the PV input mode (parallel mode/ independent mode) setting of the HYD-ES inverter. If the setting is incorrect, change the PV input mode.
How to fix SD card fault on Sofar HYD-ES Inverter?
Normally, ID98 is caused by a loose SD card holder. Click and take out the SD card, press the SD card holder, then insert the SD card back in. This should solve the problem.
What to do if Sofar HYD-ES Inverter communication board EEPROM is faulty?
ID95-ID96 are internal faults of the HYD-ES inverter. Switch OFF the HYD-ES inverter, wait for 5 minutes, then switch it back ON. Check whether the problem is solved. If not, please contact SOFAR technical support.
What causes battery high temperature protection while discharging on Sofar Inverter?
Ensure the battery is in a well-ventilated place. Try decreasing the maximum discharge (A) or/and maximum charge (A) to see if the problem is resolved.
Why Sofar HYD-ES Inverter can't communicate with Lithium battery BMS correctly?
The battery might not be compatible with the HYD-ES inverter. Ensure that the battery you are using is indeed compatible. Also, verify that you have selected the correct battery type within the settings. Check the communication cable between the battery and the HYD-ES inverter, CAN communication is recommended. For PYLONTECH US2000 PLUS battery, if you’re using RS485 communication, the ADD DIP switch should be all down.
Why Sofar HYD series inverter switches OFF when battery voltage is too low?
The HYD-ES inverter will switch OFF when the battery voltage is too low. This is a protection mechanism for the battery.
