Product introduction

Function Introduction

Compared with the traditional off grid inverter system, the biggest difference between the new off grid inverter system and the traditional off grid inverter system is that there is no need for batteries or a small amount of batteries, so as to reduce the initial investment cost, make full use of new energy to generate electricity, and achieve the purpose of reducing the use of grid electricity or diesel generator. The new off grid inverter system consists of solar panels, combiner box, new off grid inverter and other components.

The electric energy generated by solar panels is directly connected to the new-type off grid inverter after converging through the combiner box, and then DC is converted to AC through the new-type off grid inverter for the use of load equipment.

The diesel engine / power grid is connected through the AC input terminal of the new off grid inverter, and it will participate in the inverter after rectification. When the power supply of solar panel is insufficient, it will automatically switch and supplement, and the switching time is Oms.

In the system with a small number of batteries, some solar panels are connected to the controller to charge the batteries. The battery plays a supporting role in the switching process between solar panels and diesel generator, so as to avoid power failure of the system during the switching process.

In some application, the new off grid inverter can also be used in wind power, hydropower and other systems.
