All-in-one Energy Storage System

GRES is intelligent power supply equipment integrating lithium battery, PV controller and MPCS. Across different application scenarios, lithium battery, bidirectional DC / AC converter, static transfer switch and power management system can be combined as required to conduct grid-connected, off-grid power supply, as well as static reactive power compensation, harmonic suppression. GRES (grid renewable energy storage power supply) can also be connected to power grid, lithium battery or other loads to provide users with green and noise-free power supply. Additionally, the GRES system features easy installation and operation.

Application

To meet industrial and commercial demand management, peak shaving
To conduct peak shaving during high power demand periods and valley filling during off-peak hours
To serve as backup power
Power storage though wind and solar energy, peak and frequency regulation
To form a microgrid system
Integrated design for quick delivery

Features

Safe and reliable

High quality LFP battery cells
Air-conditioning battery system is placed inside to ensure optimal temperature for operation.
IP54-class protection helps ensure stable operation under bad conditions
The lithium battery features a built-in Battery Management System (or BMS) and power control system (or PCS) which ensures safety and long battery life by constantly monitoring battery performance, internal temperature, and other critical elements required in safely functioning battery.

Efficient and Convenient

The integrated system is easy for installation, maintenance and capacity expansion.
It can work with PV and diesel generator for better use of energy supply.
The grid renewable energy storage system is stock available for quick delivery.
Remote monitoring of battery’s current, voltage, temperature, SOC, device status allows users to identify the faults of the system in time.

Lower cost

Grid-connected and off-grid power supply
Peak shaving and valley filling of power consumption
Harmonic suppression is available in the system to promote a more balanced 3-phase power
Smaller size, lighter weight, less space and lower installation cost.
Longer service life, lower failure rate to reduce operation and maintenance cost.
Wind and solar energy is used to help cut the cost of electricity.
