We may earn a commission.An air conditioner draws several times its running current for the first moment of every compressor start, and that surge is usually what decides the size of the inverter or generator behind it. A soft starter ramps the compressor up instead, so the start looks much closer to the running load. Micro-Air rates this one for units under 6 tons and claims a 75% cut in inrush. Worth pricing against the inverter and battery it would let you avoid buying, which is often the larger number.
