Three-Phase Power Pinverter with Built-in Charge Controller
PRODUCT OVERVIEWL:
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 area, etc.
