This is a 12V DC battery backup inverter that keeps a sump pump running when the grid goes down. It switches automatically to battery power and delivers 3000W continuous, 6000W peak, as a pure sine wave at 120V AC. A built-in charger tops the battery at up to 30A, and an LCD shows system status. Batteries are not included, so you supply a 12V deep-cycle battery. It suits homeowners who want basement flood protection during outages and who can wire a dedicated battery bank. Against plug-and-play backup pumps, it is more flexible and more powerful, but it needs more setup and a separate battery.
