current high
2. PV(+) or PV(-) earthed
· inverter enclosure too hot
· temperatrue sensor fault
· PV array's Voc high
· grid voltage out of the
setting range
· PV(+) or PV(- ) earthed
· AC side DC bias high

Correctie Measure
restart the inverter
· check PV input voltage within
450Vdc(up to 3.0kw model),
500Vdc(up to 5.0kw model)
· check AC connector, circuit breaker
well connection
· grid back to the normal, the inverter
will restart automatically
· replace the AC circuit breaker
· check AC connector well
connection
· after seceral retart the fault remains,
replace inverter
1. check the AC output wring and
restart the inverter
2. check PV array wiring
· turn off the inverter still the
temperature down to the normal. Or
install the inverter at a well ventilated
site.
· replace the temperature sensor
· re-design the PV array
configuration
· measure the PV array voltage is the
same as inverter displayed.
· grid back to the normal, the inverter
will restart automatically
· check Country standard setting is
correct
check the resistance between PV(+)
and ground, PV(-) and ground bigger
than 2MΩ.
restart the inverter
· the inverter will restart automatically
· check the AC output wring and
restart the inverter
restart the inverter
· grid back to the normal, the inverter
will restart automatically
· check inverter frequency setting
range correct
