Product Introduction

The non-isolated and two-stage station type photovoltaic grid-connected inverter adopts two-way independent step-up modules and multi-level inverter. The protection degree of this product is IP65 and it is suitable for indoor and outdoor installation.


Product Features

Integrated aluminum body is compact in structure. Heat dissipation on three sides combined with special heat sink design can meet the cooling requirements under harsh conditions;

No-fan natural convection heat dissipation design enhances operation reliability and reduces loss;

Low voltage start and wide operating voltage range increase solar energy utilization;

The two-way MPPT adapts to different PV input conditions and enhances adaptability to complex environment;

Multiple circuit protection and fault automatic detection record increase the reliability of the equipment;

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