Charging depleted batteries
The Auto Power Inverter Charger
allows start up and through power with
depleted batteries.
For 12VDC models, after the battery
voltage goes below 10V, if the switch is
still(and always) kept in “ON” position,
the inverter is always connected with
battery whose voltage doesn’t drop
below 2V, the inverter will be able to
charge the battery once qualified AC
inputs.
Before the battery voltage going be-
low 9VDC, the charging can activated
when the switch is turned to “Off”, then
to “ON”.
When the voltage goes below 9VDC,
and the power switch is turned to
“OFF” or disconnect the inverter from
battery, the inverter will not be able to
charge the battery once again, be-
cause the CPU lose memory during
this process

The charging capacity will go to peak in around 3 seconds, this may probably cause a generator
to drop frequency, making inverter transfer to battery mode.
It is suggested to gradually put charging load on the generator by switching the charging switch
from min to max, together with the 15s switch delay, our inverter gives the generator enough time
to spin up.
Changing max charging current
The battery type selector position of “0” will disable battery charger.
The “Charge Current Control” knob will enable the user to control the max charging current from
15% to maximum.
Plug in BTS to get max charging capacity
The inverter charger will output max capacity when the BTS is plugged in. Without BTS, it will
output a max of 25A.
