Description
The grid voltage
is abnormal.
The grid frequen-
cy is
abnormal.
The inverter GFCI
exceeds
standard.
The BUS voltage
is lower than
normal.
The BUS voltage
is over
maximum value.
Suggested solutions
• Make sure that the grid does not show
any abnormalities or eliminate them if
so.
• Restart the inverter and wait until it
functions normally.
• Check the PV string for direct or indi-
rect grounding phenomenons.
• Check the peripherals of the inverter
for current leakage.
• Check the input mode setting is cor-
rect.
• Restart the inverter and wait until it
functions normally.
