Product Introduction

Huijue Group's Industrial and commercial distributed energy storage, with independent control and management of single cabinets, has functions such as peak shaving and valley filling, photovoltaic consumption, off-grid power backup and flexible capacity expansion. Modular design, 100% factory pre-assembled, can be quickly integrated and deployed without affecting production operations/building comfort. Through the unified scheduling and management of the EMS system and the cloud-based automated inspection system, equipment abnormalities can be sensed in advance to further improve the safety of the energy storage system. Support multi-mode operation to realize energy storage system benefits.

Features

1. Fast power response, supporting virtual power plant, grid-connected, off-grid and other modes

2. All-in-one design greatly reduces transportation, on-site installation time and cost

3. Local collection, intelligent monitoring, remote operation and maintenance

4. Standardized interfaces allow multiple machines to be connected in parallel, making it easy to expand and ensure batch manufacturing processes.

5. Intelligent installation and operation, supporting node adaptation, fault indication, etc., reducing on-site and operation and maintenance workload by 70%

6. No isolation design, improve system efficiency, independent single cluster battery, no circulation, reduce power loss

7. Six-layer security protection design, multi-information integration

8. Local/remote upgrade, supports broadcast program upgrade, and improves efficiency by more than 90% compared to traditional point-to-point upgrade

Application

1. Peak shaving and valley filling

Discharge during peak electricity demand to reduce expensive electricity bills

2. Improve the stability of the power system

Smooth out the intermittent output of renewable energy by storing electricity and dispatching it when needed

3. Backup power

Provide power to the load when the power grid is out of power, or use as backup power in areas without power.

4. Peak and valley arbitrage

Arbitrage by using peak and valley electricity prices in different time periods

5. Optimize the utilization of renewable energy

Loads during the day maximize the use of photovoltaic power, while excess power is stored for use at night

6. Reduce investment costs in power grid upgrades and transformations

In the application of distributed power system scenarios, the initial investment in power grid construction can be reduced.
