My 12v 4K/8k inverter is consuming 20 amps and my demand is only
2.08 amps is this normal seams a little inefficient to me, does anyone
know of a more efficient 3k/6k 12v inverter.
RCinFLA said:U.S. power grid residential service cost is based on real power and doesn't charge extra for poor power factor loads so manufacturers don't put in extra cost to improve device power factor. Europe has more regulations on power factor for devices consuming more then 75 watts. One of worst offenders in U.S. are inverter-based refrigerators, touting high efficiency, with very poor power factors in 0.6 -0.7 range. Terrible for powering by a battery based inverter. Manufacturers specifically have different unit design for U.S. versus Europe market as they can save a buck or two on manufacturing cost by not including power factor correction for product targeted to U.S. market.
