Fault Description
Actions
1
PV voltage
error
01-01
Low PV voltage
Check whether the PV panel is connected
properly, damaged, covered with dust, or
blocked by any objects.
01-02
High PV voltage
Check whether the PV panel is connected
properly, and whether the PV voltage is higher
than the maximum working voltage of the
inverter.
01-03
Short circuit of PV panel
Check whether the PV panel is short-circuited.
2
BUS
voltage
error
03-01
Low BUS voltage
This fault usually occurs in the early morning.
Please check the cleanliness of the PV panel
surface.
03-02
High BUS voltage
Check whether the PV panel is connected
properly, and whether the PV voltage is higher
than the maximum working voltage of the
inverter.
03-04
