This 2000 watt 24 volt low frequency AIMS Power inverter charger is three products in one. An inverter that 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. A built-in 30 amp transfer switch, which will automatically detect when you're switching from shore power to battery-bank power. A built-in 30 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. Combine this inverter charger with a deep-cycle battery bank for off-grid home or business, solar, mobile and emergency backup power. This inverter is also available in 12 and 48 volt models. The 2000 watt 12 volt Pure Sine Inverter Charger and 2000 watt 48 volt Pure Sine Inverter Charger are in stock and ready for same-day shipping as well. It's an industrial-grade unit with the ability to withstand surges of up to 6000 watts for 20 seconds, and it achieves this by virtue of its direct connect terminal block. This feature is one of the more sought-after in the inverter industry, allowing users to surpass the 1,500 watt maximum output of a GFCI outlet that would typically be seen on an inverter. This inverter also features a battery-type selector, which helps user regulate the voltage going into the battery bank. This capability can be a big money-saver since treating the battery bank properly will maximize its lifespan. Use this inverter to power tools on a work truck, as it will run most electric chainsaws, portable grinders, shop vacs, and more. Or use it to power appliances in your RV, as it won't produce any annoying noise or pollution.
