Fault
If the fault occurs occasionally, the possible cause
is that the external circuits are abnormal
occasionally. 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, then
check the insulation conditions of PV cable.

Internal faults of inverter, switch OFF inverter,
wait for 5 minutes, then switch ON inverter.
Check whether the problem is solved.
If not, please contact SOFARSOLAR technical
