4 Protections
No. Protection Instruction
1
PV limit
current
When the charging current of the PV array exceeds its
rated current, it will be charged at the rated current.
NOTE: When the charging current exceeds the PV array's rated
current, ensure the PV open-circuit voltage no exceed the "maximum
PV open-circuit voltage." Otherwise, the inverter/charger may be
damaged.
2
PV reverse
polarity
Fully protect against PV reverse polarity, correct the
wire connection to resume the regular operation.
3
Night reverse
charging
Prevent the battery from discharging through the PV
module at night.
4
Utility input
over voltage
When the utility voltage exceeds 264V, it will stop utility
charging/discharging.
5
Utility input
under voltage
When the utility voltage is less than 176V, it will stop
utility charging/discharging.
6
Utility input
over current
Utility input current higher than a specified value, the
device will go into protection mode automatically. Press
the over current protection device to resume working
when the utility input current decreases to the expected
value.
7
Battery
reverse
polarity
When the PV array and utility are not connected with the
inverter/charger, reverse battery polarity will not damage
the inverter/charger. It will resume normal running after
the mis-wiring is corrected.
8
Battery over
voltage
When the battery voltage reaches the Over Voltage
Disconnect Voltage point, the inverter/charger will stop
charging the battery to prevent battery damage due to
over charged.
9
Battery over
discharge
When the battery voltage reaches the Low Voltage
Disconnect Voltage point, the inverter/charger will
automatically stop discharging the battery to prevent
battery damage due to over discharge.
