SCU Power Converters: Bidirectional power converters

GRES 50-150kw

GRES 50-150kw


GRES (Grid & renewable energy storage system) static generator is an intelligent and modular power supply system, integrating lithium battery and multi-functional bidirectional energy storage converter (MPCS). It includes bidirectional AC / DC converter, bidirectional DC / DC converter, and touch screen. It can be equipped with photovoltaic MPPT to build a microgrid, and can also be equipped with STS static transfer switch to realize seamless switching between on and off the grid. The system can use lithium battery to intelligently combine photovoltaic, utility grid, diesel generator and load together, realize multi energy complementary and strategic intelligent power consumption, and provide users with high-quality energy consumption service with high economy, high reliability and high security.


Integrated system, standard modular power module and battery module;

With photovoltaic system access, easy to set up microgrid;

Replace diesel generator for backup power, and the off grid switching time is less than 10ms;

Multiple working modes:Peak shaving, backup power supply, PV and engergy storage system etc.

It can realize reactive power compensation, harmonic suppression and improve three-phase unbalance;

IP55,safe and reliable operation in outdoor environment;

Easy to install and make maintenance, intelligent charging and discharging strategy;

Can be fixed on the ground or mounted on vehicle, can be loaded and unloaded by forklift and hoisted by lifting ring;

Green energy, low noise, no fuel consumption, zero pollution;

DC, AC multi-layer protection, maximum safety performance design;

Serially designed PCS and battery pack can eliminate circulating current and improve system reliability and maintainability;

Remote monitoring and equipment management, remote troubleshooting and data analysis;
