3KW 3.5KW 5KW 48V ON/OFF GRID SOLAR INVERTER
Product Introduction
Olu on/off grid solar energy storage inverter combines the functions of inverter, MPPT solar controller and battery charging to provide stable power supply for electrical equipment in areas without power, power shortage and power instability. At the same time, it can also connect excess power into the power grid. The product is based on full digital intelligent design and adopts advanced SPWM technology to output pure sine wave and convert DC into AC. it is suitable for AC loads such as household appliances, electric tools, industrial equipment, electronic video and audio. The LCD display design is adopted to display the operation data and operation status of the system in real time. Comprehensive electronic protection function ensures that the whole system is safer and more stable.
