The AIMS Power PWRIG300024120S is a pure sine wave inverter that converts DC power from batteries into 120V AC household power, supplying 3000 watts of continuous power and 6000 watts of surge power. It features a digital signal processor (DSP) for stable 120V AC output, is suitable for sensitive loads, and has a high surge output capacity for devices with quick startup surges. The inverter has various protection circuits to handle low voltage, sudden power changes, and rapid environmental temperature changes. It also suppresses RF noise produced during conversion.
