A battery energy storage system (BESS) is an advanced technology solution that can store energy for later use in a variety of ways. Given that energy supply can fluctuate due to weather, blackouts or geopolitical reasons, battery systems are essential for achieving a continuous supply of electricity to utilities, businesses and homes. No longer an afterthought or an add-on, battery energy storage systems are an essential pillar of any energy strategy, especially any energy strategy that harnesses renewable solar energy. The sun is a fantastic energy engine, but it has an important limitation: without sunlight, you can’t generate electricity. By combining battery energy storage with photovoltaic solutions, batteries can mitigate the intermittency of renewable energy, storing solar energy generated during the day for use at night, ensuring a stable supply of electricity is always available.
Description
DingTalk-SSNJ and energy storage cabinet is an intelligent industrial and commercial energy storage cabinet independently developed by SSNJ and relying on the DingTalk digital plat form and produced by EVFREY. lt adopts a doud-edge-integrated distributed architecture.allowing the power station system to be built in a building block manner, and combined with DingTalk intelligent connection, users can easily and quickly manage equipment in the doud.
Adhering to the design concept of “All-in-One”, SSNJ creatively integrates long-life cells high-efficiency bidirectional balanced BMS, high-performance PCS, active safety system intelligent power distribution system and thermal management system into a single cabinet to form an integrated smart energy block product eBlock, which greatly simplifies installation and operation and reduces costs.
ALL-IN-ONE INTEGRATION
SE233 industrial and commercial intelligent liquid-cooled energy storage cabinet has been
comprehensively upgraded in terms of design concept, safety protection, system management
and operation and maintenance, and can be installed and used outdoors to meet users’ needs for
peak shaving, new energy consumption, backup power and other functions.
- Peak-load Shifting:The energy storage system is used to store electricity during the period when the electricity price is low, and the stored electricity is used during the period when the electricity price is high to reduce the cost of electricity use.
- Photovoltaic Energy Storage:Through the joint application of battery energy storage system and renewable new energy, the randomly varying output power is converted into relatively stable output.
- Back Up Power:When the power is interrupted, the uninter- rupted short-term power supply is carried out for important loads, reducing the economic losses caused by the sudden power loss of the load.
- Integrated solutions to save energy and grow your business
- Virtual Capacity Addition:
OPERATIONAL HIGHLIGHTS
- The integrated smart energy block product eBlock, with the cloud platform and applet monitoring operation, greatly simplifies installation and operation and maintenance.
Advantages of battery energy storage system
- Environmental benefits: Installing a renewable energy battery storage system at a home or business reduces pollution, thereby contributing to the energy transition and combating the effects of global warming.
- Reduced energy costs: Storing low-cost energy and using it during peak hours when electricity rates are higher saves money by allowing users to shift consumption and avoid higher bills. When combined with free solar energy, the savings are even greater.
- Reduced reliance on the grid: Battery storage systems guarantee a continuous supply of energy, even when the grid is unstable due to peak demand or extreme weather.
- “Always on” power supply: The sun is not always “on”. Battery storage systems work 24/7 so any fluctuations in solar supply can be compensated by storing excess power in the system.
- Resilience: Battery storage systems provide emergency backup power during power outages, ensuring business continuity.
