The inverter detects that the
ground leakage current exceeds
the limitation.
PV input voltage exceeds the
upper limit.
The voltage of bus circuit is too
high
The inverter detects its high
internal temperature
The ground cable is losse or in
poor connection
Internal communication got
failed. Caused by a strong
external magnetic field etc.
Internal storage got abnomal.

1. Restart the inverter.
2. Check whether the PV panels, cables, and
connectors are waterlogged or damaged.
3. Seek help from the installer or manufacture.
Reduce the number of PV panels to make sure
that the open-circuit voltage of each string is
lower than the inverter maximum allowed input
voltage.
1. Check whether the input voltage exceeds the
limit.
2. Restart the inverter.
3. Seek help from the installer or manufacture.
1.Check whether the inverter installation location
is well ventilated.
2.Try to turn it off for a while, and then power it
back on when it cools down.
3.Seek help from the installer or manufacture.
Check whether the ground cable wiring is
cor¬rect.
1. Restart the inverter.
2. Seek for help from the installer or manufacture.

1. Use multimeter to measure the voltage
be¬tween N&PE cable on AC side. If the voltage
is higher than 10V, which means the neutral or
