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 does not exceed the "maximum PV open-circuit voltage."
Otherwise, the inverter/charger may be damaged.
Fully protect against PV reverse polarity, correct the wire connection to resume
the regular operation.
Prevent the battery from discharging through the PV module at night.
In the 110V/120VAC system, when the utility voltage exceeds 132V, it will stop
utility charging/discharging.
In the 220V/230VAC system, when the utility voltage exceeds 264V, it will stop
utility charging/discharging.
In the 110V/120VAC system, when the utility voltage is less than 88V, it will stop
utility charging/discharging.
In the 220V/230VAC system, when the utility voltage is less than 176V, it will
stop utility charging/discharging.
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.
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.
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.
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.
When a short circuit occurs at the load output terminal, the output will be turned
off immediately. The output will then be automatically restored after a delay (the
first time delay for 5s, the second time delay for 10s, the third time delay for 15s).
If the short circuit remains after three times delay, clear the fault and then
restart the inverter/charger to resume work.
