Solar Energy Storage

An intelligent comprehensive energy solution, which realizes the reasonable cooperation between wind, solar, energy storage battery, power grid, and diesel generator, makes scientific use of all kinds of mobile energy storage and provides users with green, low-cost, convenient, and high-quality power services.

What is Solar Energy Storage?

Grid Renewable Energy Storage Power Supply (GRES) is an intelligent and modular power supply equipment integrating lithium battery and PCS, which can have access to new energy, power grid, diesel generator to provide users with green, environmental protection, noise-free, high reliability, and high-security power services such as solar battery storage.

GRES Static Generator Key features

Safe and reliable

High-quality li-ion cell; Intelligent air cooling design, long service life; IP54, safe and reliable operation in outdoor environment; Serially designed PCS and battery pack eliminates circulating current and improves grid connected renewable energy system reliability. Integrated BMS, DC, AC multi-layer protection, maximum safety performance design.

Efficient and Convenient

No air conditioning design, high energy efficiency. Modular design, easy for installation, maintenance and capacity expansion; Easy access to PV and diesel generator; Fixed on the ground or mounted on vehicle, can be loaded and unloaded by forklift and hoisted by lifting ring; Remote monitoring and equipment management, remote troubleshooting and data analysis.

Cost optimization

One investment, multiple benefits: Peak shaving, backup power supply, micro grid building, power quality improving and great application in the solar battery energy storage system, etc. Small size, light weight, less space and installation cost; Long cycle life, low failure rate, reduce operation and maintenance investment; Maximize green energy utilization.
