RV Energy Storage Battery Charging

There are five reliable ways to charge your RV battery: Shore power is a common method of charging an RV battery when you have a power connection at a campground or RV park. When you plug your RV into an AC outlet, the built-in converter transforms the AC power into DC to charge the battery.

An RV solar battery charger is a system that charges your RV batteries with solar power. In fact, this refers to practically any RV solar system you hear about. At their core, every single system has one basic function: to charge your RV batteries.

Unless you plug into a power source (i.e. shore power or generator), your RV batteries supply all the power to your RV. Without a battery charger, your fridge, furnace, lights, and any other electronics will not work. All RVs have chargers that run when plugged into shore power or run a generator.

When you plug your RV into an AC outlet, the built-in converter transforms the AC power into DC to charge the battery. To recharge your RV battery using shore power, connect your RV battery's converter to a 120V AC outlet at a campground or other power source.

The RV can use power directly from the charge controller and the battery at the same time. Also, the batteries will store additional solar charge for use at night or when there is not enough sun to power the RV, like on cloudy days. Charge controllers watch both the voltage of the batteries and solar panels to match the power.

If your RV battery is LiFePO4 model, consider the Redodo 12V 20A LiFePO4 battery charger to make charging easier. It charges 2x faster than an ordinary 10A battery charger and can fully charge a 12V 100Ah LiFePO4 battery in 5 hours. It is recommended to charge your RV battery at a 0.2C charging rate.
