    1. Basic Information 1.1 Product overview and characteristics AU48-H series is a new type of mixed solar energy storage inverting & control all-in-one machine integrating solar energy storage & municipal power charge storage and AC sine wave output. It adopts DSP control and advanced control algorithm to achieve characteristics of high response speed, high reliability and high industrial standard.

  • Page 5: Basic System Introduction

    13.It has the function of mixed load: when the battery is not connected, photovoltaic and commercial power can supply power to the load at the same time (if there is no battery, the commercial power must be connected). When the battery is full, it can also enter the mixed load mode, which can make full use of the photovoltaic energy.
