The NeoVolta NV 14 Energy Storage System is a fully integrated alternating current (AC) or Direct Current (DC) hybrid (120V / 240V) Residential Energy Storage System. Built with a lithium iron phosphate battery, our solar batteries outperform any competitors made with lithium ion. Our NeoVolta batteries are built with stability in mind and therefore have superior thermal and chemical stability compared to lithium ion batteries, as well as a longer life cycle, and are non-toxic and cobalt-free. With the ability to be stored either indoors or outdoors, as well as capable of being integrated with a generator, the installation process is straight forward and flexible. Thanks to the rapid auto transfer switch, your home will continue to be seamlessly powered when the grid goes down with either your solar or stored energy in the solar battery. Based on a typical house usage of 500 watts, your NeoVolta NV 14 energy storage system can provide up to 28 hours of power during an outage. With a 10 year warranty, our remote monitoring system, and a federal tax rebate, we make the choice easy for you to choose the best solar battery on the market.
