The KISAE Abso 2000 inverter/charger converts 12V battery power into pure sine wave AC household power, allowing you to run loads up to 2000 watts. It features a built-in multi-state 55 amp charger to ensure batteries are recharged safely and efficiently as well as an integrated 30A transfer switch with supplementary breaker. This provides for a smooth transition between shore power and battery power, while the automatic AC load sensing feature will prevent tripping the shore power circuit breaker. The KISAE Abso 2000 features pure sine wave output and is ideal for operating motor loads and reducing stress on surge protection circuitry, meaning potentially longer equipment life. Perfect for small microwave ovens, computers, televisions, power tools and more. The KISAE Abso 2000's efficient design and compact dimensions allow for installation in a variety of locations and the detachable digital display can be mounted anywhere for convenient remote control. The Abso 2000 is designed to offer reliable AC power and battery charging to RV's, boats, trucks, homes and cabins.
