In Stock
Note: This has "MPPT" in the title and listing, but that may not be accurate based on the price point and weight; please verify before purchase. Low-cost 12/24V controller listed at 100 A, with an LCD, two USB ports, manual load switching and 99.0% tracking efficiency. Its 13 mA self-consumption is among the lowest listed, and the warranty is 360 days, suiting buyers wanting a basic budget controller for a small 12V setup. A 100 A rating at 10 oz (280 g) is unlikely, since other 100 A MPPT units listed weigh over 6.6 lbs (3 kg).
