APS inverter/charger provides pure sine wave power for all alternative energy needs. This inverter/charger supplies 2000W of continuous 230Vac power. Reliable large transformer design and frequency control powers resistive loads like refrigerators, motors, pumps, compressors and laser printers as well as electronic loads like TV’s, computers, power tool and battery chargers. The 3-stage charging system will properly charge and maintain vehicle's battery or separate battery bank. The charge rate is selectable so you can use variety of battery sizes as well as multiple batteries to fit run time requirements. Versatile inverter/charger system with seamless transfer switching serves as an automotive inverter for RVs, over-the-road trucking, conversion vans, fleet service vehicles, standalone alternative power source for off-grid, alternative energy or export applications and as an uninterruptible power supply (UPS) for items compatible with 10ms transfer time.
