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
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.
