connected to shore power and transforms it into direct current to recharge your batteries.
There are two modes of operation associated with an inverter/charger: Inverter Mode:

capacity and age. Other factors such as the battery’s state of charge and temperature can also affect the
length of time your appliances can run.

this application.
