Product Description

20kw single phase solar power inverter with charge controller
96V/192V/220V/384V

Introduction

The product is an intelligent inverter with built-in charge controller designed for large photovoltaic power generations. Its built-in control r 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. 
 

Product Features                                                 

• DSP intelligent control technology,high peformance;
