Charging way
Charge Stage
Transition Definitions
(1)Boost CC Stage: If A/C input is applied, the charger will run at full current in
CC mode until the charger reaches the boost voltage.
(2)Boost CV Stage: the charger will keep the boost voltage in Boost CV mode
until the T1 timer has run out. Then will drop the voltage down to the float voltage,
when the charging current is lower than 20% setting value.
(3)Float Stage: In float mode, the voltage will stay at the float voltage. If the A/C
is reconnected or the battery voltage drops below 12Vdc/24Vdc/48Vdc, the
charger will reset the cycle above.

13 Overloaded
happens
Overload is not permitted when the inverter
is in battery mode. If overloaded, please turn
off the inverter, then decrease
the load to less than the
rated output power of inverter. Once
achieved,turn the inverter back on.
If overload and the AC input is on, wait for
30s and it will clear away the fault
automatically and work normally
14 Output voltage

Restart the inverter or Contact
our Support Desk.

If AC input is on, cut off the AC input
first and then turn off the inverter,voltage)
disconnect all AC output wiring and turn
on it. If the screen still displays a fault,
please connect our Support desk. If the
inverter works, please check the output
wiring and load, making sure settings do
not cause short circuiting

Read the battery voltage from the screen,
and measure the voltage of battery with
multimeter. If both the voltage readings are
more than 60v, the battery may have an
issue – cease operation in this case.

01 Overload
In Battery mode, the inverter will not permit over-load,
the max working time will depend on the percent of
load. Utility mode, the inverter allow to overload but
the maximum current will be less than 30A.

Read the voltage from the screen and confirm the
voltage ofAC input is about 90-170v. If it is ,means
the voltage ofAC input is low, it should still work normally.
