ID28-ID31 are internal faults of HYD-ES
inverter, switch OFF HYD-ES inverter, wait for
5 minutes, then switch ON HYD-ES inverter.
Check whether the problem is solved.
If no, please contact SOFAR technical
support.
The grid current is too high
The output current is too high
The input current is too high
Check whether the input current is higher
than the maximum input current of HYD-ES
inverter, then check the input wiring, if both
are correct, please contact technical support.
Check the PV input mode (parallel mode/
independent mode) setting of HYD-ES
inverter. If it’s incorrect, change the PV input
mode.
The GFCI sampling value between
the master DSP and slave DSP is not
consistent
ID48-ID51 are internal faults of HYD-ES
inverter, switch OFF HYD-ES inverter, wait for
5 minutes, then switch ON HYD-ES inverter.
Check whether the problem is solved.
If no, please contact SOFAR technical
support.
The grid voltage sampling value
between the master DSP and slave
DSP is not consistent
The grid frequency sampling value
between the master DSP and slave
DSP is not consistent
The Dci sampling value between
the master DSP and slave DSP is not
consistent
HYD-ES inverter can’t communicate
with Lithium battery BMS correctly.
Make sure the battery you’re using is
compatible with HYD-ES inverter.
Make sure you’ve selected the correct
battery type. Check the communication cable
between battery & HYD-ES inverter.
It’s recommended to use CAN
communication.
For PYLONTECH US2000 PLUS battery, and
you’re using RS485 communication, the ADD
DIP switch should be all down.
SPI communication is fault
ID53-ID55 are internal faults of HYD-ES
inverter, switch OFF HYD-ES inverter, wait for
5 minutes, then switch ON HYD-ES inverter.
Check whether the problem is solved.
If no, please contact SOFAR technical
support.
SCI communication is fault
