requirements
of
the
inverter.
3-102
Array 2 DC hard
overcurrent
The PV module operates
the current limit.
Check whether the current
configuration of the
second PV array meets the
requirements of the
inverter.
3-104
PV radiator
temperature
overheating
The PV module stops
working. After the failure
is excluded, the PV
module runs
automatically
1.Check the LCD screen to
show whether the
temperature is too high.
2.Check whether the
machine is in an easily
ventilated place.
3-105
PV DC Busbar
overvoltage
The PV module stops
working. After the failure
is excluded, the PV
module runs automati-
cally.
1. Measurement of open
circuit voltage of PV array.
2. Check whether the
connection mode of PV
module meets the
requirements of the
inverter .
3. Check whether the power
grid voltage is stable.
3-106
Array 1
overvoltage
The PV module stops
working. After the failure
is excluded, the PV
module runs
automatically
1. Operating a DC circuit
breaker to disconnect the
connection of the PV
module to the inverter.
2. Check whether the open
voltage value of the PV
array exceeds the
allowable voltage value.
3. Check whether the
connection mode of PV
module meets the
requirements of the inverter.
3-107
Array 2
overvoltage
3-111
Array bus
grounding fault
When the inverter is shut
down, the inverter is
operated automatically
after
the
fault
is
eliminated
1. Operating the DC circuit
breaker, disconnect the
connection between PV
module and inverter .
2. Check whether the
cathode
or
negative
electrode of the battery is
grounded.
