Rated Charging Amperage on Inverter Chargers

Sigineer Power’s inverter chargers are build with very strong battery chargers to recharge your batteries swiftly and safely.

When you are using a generator to recharge the batteries, 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.

Please use a small jeweler’s style flat-head screwdriver to turn the charge current control switch gently to avoid breakage due to over-turning.

To guarantee the best performance of AC charger when the AC input is from a generator, the standby generator should be of at least 150% higher capacity than the inverter.

Warning! Operation with an under-rated generator or generator with unqualified wave form may cause premature failure which is not under warranty.
