A converter in it's simplest form, provides nominal 12 volts DC from 120 volts AC (shore power) for running loads and keeping the house battery full. When you plug in or start the generator, the converter automatically takes over the DC loads.

Some RV converters are built in to the AC breaker power center. Most RV's come with a single stage converter that are inadequate as a proper battery charger.

All deep cycle battery manufacturers require multi-stage battery charging. Some manufacturers like Progressive Dynamics and Iota offer modules to upgrade your converter to a 3-stage charger. 3-stage chargers can charge your battery twice as fast as single stage converters.

For long battery life and faster charging, we recommend 3-stage converter/chargers that are designed to fully maintain your house battery.
