The perfect addition to any off-grid system, whether for a caravan or a cabin, the Renogy 3000W Pure Sine Wave Power Inverter acts as a DC to AC converter that allows you to power your household appliances. Unlike modified sine wave inverters, this 3000W inverter is a pure sine wave, capable of producing cleaner, smoother, and more reliable electricity to operate tools, fans, lights, and other electronics without interference. Many off-grid systems require a 12V solar inverter to power everyday electronics and this one includes multiple protections to help things run smoothly and safely. The AC priority function enables the inverter automatically switch from the battery (DC) to the mains (AC) and vice-vercer whenever the utility company takes/loses power!
