Warning: The output of these units will be de-rated by about 10% when the battery voltage drops below the
nominal cut off of 20V and 40V.
For other models, the battery type selector position of “9” is customized with special charging algorithm for

Note: The battery type selector of “0” will disable the charger when the battery voltage is over 11.25Vdc for
12V models, 22.5V for 24V models, 45V for 48V models.
Charging depleted batteries
Unlike some other competing inverters that need a qualified DC voltage to activate its charger, the Sigineer
Power pure sine wave inverter/charger allows start up and power bypass with depleted batteries.
As long as qualified AC power inputs, these inverters will charge batteries even when the battery voltage is
0 volt. This is a great feature to wake up lithium battereis.
Charging current for each model
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 when battery voltage is over 11.25Vdc
for 12Vdc models, 22.5V for 24V models, 45V for 48V model.
If the battery voltage is below this level, the inverter will force the charging when AC input is qualified.
