Battery Input Protection
When the charge current of the configured PV array
exceeds the nominal PV current, it shall be charged at
the nominal current.
t night, since the battery voltage is higher than the PV
module voltage, prevent the battery from discharging
through the PV module.
When the network voltage exceeds 280V (230V model) or
140V (120V model), the network load stops and the
inverter output lights.
When the network voltage is less than 170V (230V/UPS
mode model) or 90V (120V model or APL mode), the
network load will stop and the inverter output will turn on.
When the battery voltage reaches the overvoltage
disconnect voltage point, it will automatically stop the PV
and the battery charging network to prevent the battery
from being damaged by overload.
When the battery voltage reaches the low voltage cut off
voltage point, the battery discharge is automatically
stopped to prevent is damaged due to excessive shock.
When there is a short circuit failure at the charging output
end for more than 1 S, the output AC voltage will turn off
Immediately.
When the internal temperature of the all-in-one machine is
too high, the all-in-one machine will stop loading and
unloading; when the temperature returns to normal, the
all-in-one machine will resume loading and unloading.
3 minutes after overload protection, the output will be
emitted again, and the output will be turned off for 5
consecutive overloads until the machine is turned on
again. For the specific overload level and duration, refer to
the technical parameters table after the manual.
When the photovoltaic polarity is reversed, the machine
will not be damaged.
Prevent the AC battery inverter from feeding back the
bypass AC input.
Built-in AC input over current protection circuit breaker.
When the discharge output current of the battery is
greater than the maximum value and lasts 1 minute,
switch to the charged AC input.
When the battery is connected to the reverse or the
inverter is shorted, the battery input fuse inside the
inverter will blow to prevent damage or fire.
When the external battery port is shorted in the PV or AC
state of charge, the inverter will protect and stop the
output current.
