Why Sofar HYD-ES Inverter can't communicate with Lithium battery BMS correctly?
- R
  Renee MillerAug 20, 2025
  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.

What does it mean if the GFCI sampling value is not consistent in Sofar Inverter?
- R

  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.

  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 HYD6000-ES?
- A
  Ashley FergusonAug 28, 2025
  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 SD card fault on Sofar HYD-ES Inverter?
- M
  Michael LeeSep 5, 2025
  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?
- J
  Jeffrey GentrySep 7, 2025
  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.

Why Sofar HYD series inverter switches OFF when battery voltage is too low?
- R
  robert75Sep 13, 2025
  The HYD-ES inverter will switch OFF when the battery voltage is too low. This is a protection mechanism for the battery.
