The 1500 watt 24volt low frequency pure sine inverter charger is three products in one, a combination of an inverter, battery charger and AC auto-transfer switch.
1. The inverter transforms DC (direct current) power stored by batteries into AC (alternating current) electricity that can be used to power tools and appliances of all varieties.
2. A built-in transfer switch, which will automatically detect when you're switching from shore power to battery-bank power.
3. It also has a built-in 25 amp battery charger which uses AC power, like from the grid or from a fuel-powered generator, that can be used to recharge a battery bank as well. The battery-type selector on the top of the unit allows the ability to adjust the voltage provided to the bank.
4. The inverter peaks at 3000 watts with the power to run many tools and appliances with a startup surges, such as a refrigerators, freezers, microwaves and blow dryers. It is perfect for small caravan, motorhome,camping van etc
