AC Battery Chargers

Many modern off-grid inverters also double as chargers for your deep-cycle battery bank that activate automatically whenever outside AC power is available (like from an AC generator or plugging in at an RV park).

If your inverter doesn't have this feature, you'll want to hook up an AC battery charger to your generator to act as a backup battery charging source when your primary solar/wind/hydro power source isn't keep up.

Since these AC battery chargers are really just AC-DC power converters, they can directly power DC loads that aren't batteries as well.
