D01
Off-grid Fault
DC Fault
UpsOverPowerFault
PV current over, triggered
by Software logic.
• Power off, power on then restart.
• If those faults occurs continuously and
frequently, please ask help for local
distributors.
PV current over, triggered
by hardware protection
circuit
• Power off, then restart (Ref. Chapter8).
• If those faults occurs continuously and
frequently, please ask help for local
distributors.
• Adjust generator running parameters,
make the output voltage, frequency in
allowed range.
• If this fault occurs continuously and
frequently, please ask help for local
distributors.
0ff-grid load over
• Reduce loads.
• If sometimes overload, it can be
ignored, when generation power enough
can be recovery.
• If those faults occurs continuously and
frequently, please ask help for local
distributors.
D02 GridConflictFault
Grid connected to Back-up
terminal
• Check the off-grid port connection
correct, disconnect both off-grid and grid
ports.
