In early 2022, our company officially launched the off grid energy storage inverter independently developed and produced by OULU.
The off grid energy storage inverter combines the functions of inverter, MPPT solar controller and battery charging to provide uninterruptible power supply for electrical equipment. 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. 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.
Performance:
● pure sine wave solar inverter;
● output power factor 1;
● high photovoltaic input voltage range;
● battery independent design;
● built in 80A MPPT solar charger;
● battery equalization function, optimize battery performance and prolong battery life.
