This power frequency off-grid solar inverter is the perfect solution for areas where electricity is scarce or unreliable, such as mountain regions, rural areas, military outposts, islands. It takes DC power and converts it to AC power via a full-bridge inverter, and comes in sizes ranging from 5kW to 500kW to fit the power load of any area. Outfitted with a pure sine wave output and advanced protective features, the off-grid solar inverter also boasts a highly efficient performance with a low no-load loss, making it an ideal choice for solar/wind energy and energy storage power station power generation systems.
Product Details
Our solar inverter is designed with user-friendly features, a sophisticated look and simple operation. The clear LCD display and efficient operation create a low noise and non-polluting power source that is ideal for industrial control systems, in civil, train, marine and automotive applications, as well as fire power and other power management systems.
The pure sine wave AC output is also suitable for other scenarios requiring rock-solid AC voltage transfers. With its careful design and construction, our product delivers convenient and reliable power control solutions and meets the highest quality and security requirements of power control systems, while also delivering a dependable and effective power supply for the connected terminals.
