HJ-ESS-DESA series ( 215KWh - 1075KWh )
Huijue Group's industrial and commercial distributed energy storage, independent control and management of a single cabinet, has the functions of peak shaving and valley filling, photovoltaic consumption, off-grid backup power, and flexible expansion. Modular design, 100% factory pre-assembled, can be quickly integrated and deployed without affecting production operation / building comfort. Through the unified scheduling management of the EMS system and the automatic inspection system in the cloud, the abnormality of the equipment can be detected in advance to further improve the safety of the energy storage system. Support multi-mode operation to realize energy storage system benefits.
Features
Fast power response, supporting multiple modes such as virtual power plant, grid-connected , and off-grid
All-in-one design greatly reduces transportation, on-site installation time and cost
Local collection, intelligent monitoring, remote operation and maintenance
The standardized interface can connect multiple machines in parallel, which is easy to expand, and the batch manufacturing process is easier to guarantee
Intelligent installation, operation and maintenance, support node self-adaptation, fault indication, etc., reducing on-site and operation and maintenance workload by 70%
No isolation design, improve system efficiency
Independent single cluster battery , no circulating current, reduce power loss
Through the combined use of outdoor inverter control cabinets, distributed
Modular storage capacity of energy storage system to meet large-scale application scenarios
Local / remote upgrade, support broadcast program upgrade, compared with traditional point-to-point upgrade efficiency increased by more than 90%
Application Scenario
Shaving peaks and filling valleys
during peak electricity demand to reduce expensive electricity bills
Improve the stability of power system
by storing electricity and dispatching it when needed
backup power
when the grid is out of power, or use as
backup power in areas without power
peak valley arbitrage
Arbitrage by using peak and valley electricity prices in different time periods
The utilization of renewable energy
the day maximize photovoltaic power usage, while excess power is stored for use at night
Costs for power grid upgrades
Reduce the initial investment in power grid construction under the application of distributed power system scenarios
