The AIMS 1000-Watt pure sine inverter charger is a combination of an inverter, battery charger and AC auto-transfer switch into 1 complete system with a peak DC and AC conversion efficiency of 92%. It is packed with unique features and it is 1 of the most advanced inverter chargers in the market today. It features power factor corrected, sophisticated multi-stage charging and pure sine wave output with unprecedentedly high surge capability to meet demanding power needs of inductive loads without endangering the equipment. The powerful battery charger of this inverter charger is capable of 120-Volt at 35 Amp, and with power factor corrected, it uses 20% to 30% less energy from AC input than a standard charger, avoiding nuisance breaker trips or generator overloads. In response to the increasing demand of more advance battery charging, this model is equipped with Batter Temperature Sensing for increased charging precision. The overloads capacity is 300% of continuous output for up to 20-seconds to reliably support tools and equipment longer. The transformers have been consistently improved for years to achieve the best balance of conversion efficiency, idle consumption and minimum THD. The idle consumption of the line is ultra-low, roughly 1.5% of its rated power. The AC battery priority switch and auto generator start functionally making it ideal to work in either backup power or renewable energy applications.
