Protection Feature
Instruction
1
PV input current/power limiting
protection
When the charging current or power of the PV array configured exceeds
the PV input rated value, the inverter will limit the input power and charge
at the rated.
2
PV input over-voltage
If the PV voltage exceeds the maximum value allowed by the hardware,
the machine will report a fault and stop the PV boost to output a
sinusoidal AC wave.
3
PV night reverse current
protection
At night, the battery is prevented from discharging through the PV module
because the battery voltage is greater than the voltage of PV module.
4
AC input over-voltage protection
When the AC input voltage of each phase exceeds 280V, the mains
charging will be stopped and switched to the inverter mode.
5
AC input under-voltage
protection
When the AC input voltage of each phase below 170V, the utility charging
will be stopped and switched to the inverter mode.
6
Battery over-voltage protection
When the battery voltage reaches the over-voltage cut-off point, the PV
and the utility will automatically stop charging to prevent the battery from
being overcharged and damaged.
7
Battery under-voltage protection
When the battery voltage reaches the under-voltage cut-off point, the
inverter will automatically stop the battery discharge to prevent damage
from over-discharging the battery.
8
Battery over-current protection
After a period when the battery current exceeds that allowed by the
hardware, the machine will switch off the output and stop discharging the
battery.
9
AC output short-circuit
protection
When a short-circuit fault occurs at the load output terminal, the AC
output is immediately turned off and turned on after 1 second.If the
output load terminal is still short-circuited after 3 attempts, the inverter
must be manually restarted after first removing the short- circuit fault
from the load before the normal output can be restored.
10
Heat sink over-temperature
protection
When the internal temperature of the inverter is too high, the inverter will
stop charging and discharging; when the temperature returns to normal,
the inverter will resume charging and discharging.
