LLCBus voltage is too high and has
triggered hardware protection
ID09- ID26 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.
Boost voltage is too high and has
triggered hardware protection
BuckBoost current is too high and
has triggered hardware protection
The battery current is too high and
has triggered hardware protection
The GFCI sampling value between
the master DSP and slave DSP is not
consistent
If the fault occurs occasionally, the possible
cause is that the external circuits are
abnormal occasionally. HYD-ES inverter
automatically returns to normal operating
status after the fault is rectified.
If the fault occurs frequently and lasts a long
time, check whether the insulation resistance
between the PV array and earth(ground) is
too low, also check the insulation conditions
of PV cables.
The PV current is too high and has
triggered hardware protection
ID14-ID15 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 and has
triggered hardware protection
Input current is not balanced
Check the PV input mode (parallel mode/
independent mode) setting of HYD-ES
inverter. If it’s incorrect, change the PV input
mode.
The grid current sampling error
ID17-ID26 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 error
The auxiliary voltage error
LLCBus voltage is too high
Bus voltage is too high and has
triggered software protection
Battery current is too high
If the fault occurs frequently, please contact
SOFAR technical support.
