Product Introduction

SGPB500L type inverter is a kind of photovoltaic inverter without any transformer inside, which can only be integrated into the power grid through an external step-up transformer. Based on SGPB500L type 1 inverter, the photovoltaic inverter (types 2 and 3) adopts new components and new technology. With smaller size, higher power density, smaller land occupation, and less initial investment, the photovoltaic inverter (types 2 and 3) is suitable to be used indoor.


Product Features

High power density, small size, and light weight;

The maximum conversion efficiency is 99%;

The long lived AC vacuum contactor ensures 25-year reliable operation;

By using advanced control algorithm, it can adapt to complex power grid environment;

Unique airduct design with small power consumption and good heat dissipation;

Advanced islanding effect detection scheme;

It passed the authentication of low voltage and zero voltage ride through.
