Product overview

The product is an intelligent inverter with built-in charge controller designed for large photovoltaic 

power generationsits built-in controller can realize charge management for a battery pack by multiple 

solar arrays to improve charge efficlency and life of the battery pack. Thanks to the DSP control basek 

on SPwM high-trequency carer 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, pasturingaraae 

areas etc.
