China 10kw 15kw 20kw 30kw 40kw Three Phase Solar Inverter with Built-in Solar Controller for Solar System

10KW 15KW 20KW 30KW 40KW Three phase Solar Inverter with built-in solar controller for solar system

Product overview
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 base 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 generator occasions including families, schools, public lighting, industrial and mining enterprises, frontier defense, sea islands, pasturing areas and more.
