Inverters allow you to use 12V Dakota Lithium batteries to power household electronics that require 120V AC (the wall plug in your home). Rated at 1500 watts this professional grade pure sine wave inverter takes DC power (the power that comes from batteries or solar panels) and transforms it into AC power. 1500 watts is the perfect size for most off-the-grid vehicles, including mid sized RVs, boats, Sprinter or camper vans, trailers, job sites for charging power tools, or other off grid applications where you need plug and play power. 1500 watts is a good size to run a medium sized TV, stereo, small kitchen appliances, computers, small heaters, or other home electronics. As a professional grade tool, this inverter provides a pure sine wave, which is compatible with the most sensitive of electronics, including CPAP machines, medical devices, and engineering equipment. Instructions and datasheet available here. For larger power systems >1500 watts we recommend the Victron Multiplus inverter. Please note: the recommenced battery size for this inverter is a 100 Ah Dakota Lithium battery or larger.
