Description
Solution
GFCI Fault
Excessive leakage current.
1. Restart the inverter.
2. Check if the insulation of the wires in PV,
battery, and AC is damaged.
3. Seek for help from the installer or manu-
facture.
PV Over Voltage
PV over voltage is too high.
1. Reduce the number of PV panels to make
sure the open-circuit voltage of each string
is lower than the inverter max allowed input
voltage.
Bus Voltage Fault
BUS voltage is over-high.
1. Check whether the input voltage is over
the limitation.
2. Seek for help from the installer or manu-
facture.
Inverter Over Tem
-
perature
Temperature anomaly, the tempera-
ture of the interior of the inverter is
excessively high and out of the safe
range.
1. Check if the heat dissipation of the invert-
er is normal.
2. Seek for help from the installer or manu-
facture.
SPI Fault
Internal communication fails. Caused
by a strong external magnetic field
etc.
1. Restart the inverter.
2. Seek for help from the installer or manu-
facture.
E2 Fault
Internal storage anomaly. Caused by
a strong external magnetic field etc.
1. Restart the inverter.
2. Seek for help from the installer or manu-
facture.
GFCI Device Fault
GFCI device anomaly.
1. Restart the inverter.
2. Seek for help from the installer or manu-
facture.
