The 1000W Pure Sine Wave Power Inverter is a high-quality solar accessory that is perfect for off-grid systems, including cabins and tiny homes. A power inverter is an electrical device that transforms the DC power stored in batteries into standard household AC power for consumer electronic needs. Think of it as a gateway between the photovoltaic system (solar panels) and the devices and appliances drawing energy from your system.As a pure sine wave inverter, it is capable of producing cleaner, smoother, quieter, and more reliable electricity to operate tools, fans, lights, and other electronics without interference. Many off-grid systems require a 12V solar inverter to run everyday electronics. Most grid-tied systems must use pure sine wave inverters because utilities deliver pure sine waves. | Renogy | | 1000W 12V Pure Sine Wave Inverter | Black | Best Buy
