3.5KW/5.5KW Off Grid Solar Inverter

A 3.5KW/5.5KW Off Grid Solar Inverter is a power device used to convert direct current (DC) power into alternating current (AC) power to meet the power needs of off-grid systems. An off-grid system refers to a system that does not rely on public grid power supply, but generates electricity through independent energy systems (such as solar panels, wind turbines, etc.).

Off-grid inverter control all-in-one machine, supporting mains power and photovoltaic solar energy input; DPS digital control technology, double conversion online design, input PFC technology, input power up to 0.99, high-efficiency inverter topology, higher output efficiency; battery balancing function Optimize battery performance, higher energy storage efficiency; mains/photovoltaic/battery/multi-mode optimal output; support battery cold start; built-in dust filter kit, suitable for harsh environments; support WIFI communication (optional).
