The product is an intelligent inverter with built-in charge controller designed for large photovoltaic power generations. Its built-in controller can realize charge management for a battery pack by multiple solar arrays to improve charge efficiency and life of the battery pack. Thanks to the DSP control basek on SPWM high-frequency carrier technology and IGBT power device, it can control the output operation parameters accurately to provide a high quality and reliable pure sine wave AC power supply for precision equipment. It is widely applied to large solar power generation occasions including families, schools, public lighting, industrial and mining enterprises, frontier defense, sea islands, pasturing areas, etc.
+ Excellent performance because of the DSP intelligent control inversion technology;
+ A wide range of applicable loads because of pure sine wave AC output;
+ Visualization of operation status of the equipment through simple LEDs and a LCD;
+ Overall automatic protection and alarms such as output overload protection;
+ Solar array and battery common-anode system input;
+ Intelligent charge control based on programming of charge parameters, which is provided to meet the special needs of different occasions;
+ Settable battery protection parameters, and a function of password protection;
+ A function to accumulate the photovoltaic power generation capacity and the battery capacity;
+ Overall protection: Protection and alarm for reverse connection of the battery poles, battery overcharge, and back charge of the battery at night;
+ Display of the current battery voltage, battery charge current, internal temperature of the case, total photovoltaic power generation capacity (AH), total power consumption by the load, total battery level (AH), photovoltaic current when each solar battery is separately conducted, etc.
