The NTS-3200-148UN is a highly reliable, off-grid true sine wave DC-AC power inverter designed to convert a 48Vdc input into a clean AC output. It delivers 3000W of continuous power with a typical efficiency of 91% and can handle a surge power of up to 6000W. The output voltage is selectable between 100, 110, 115, and 120Vac via a DIP switch, producing a true sine wave with less than 3% total harmonic distortion (THD). This inverter operates on a DC input voltage range of 40V to 66V and features a low no-load dissipation of 1.7W in saving mode. It is suitable for a wide range of applications including off-grid solar power systems, vehicles, yachts, and powering home appliances or power tools.
