Product Introduction：
This product is a grid-tied and off-grid energy storage system, serving as an energy solution that can integrate with the grid (diesel generation), photovoltaic power generation, and lithium battery energy storage. It is primarily used in electric vehicle charging stations, industrial and commercial energy storage, buildings, factories, family villas, farms, and other locations. (Off-grid operation requires manual operation; for automatic switching between grid-tied and off-grid modes, an STS needs to be added.)
Functional features:
Flexible and Efficient: Standardized modular design enables flexible configuration, facilitates installation without parallel circulation, and significantly reduces energy loss. Safe and Stable:
Equipped with a three-level fire protection system, it achieves comprehensive protection, balanced management of batteries, and prolongs battery life. Intelligent collaboration: 3S collaboration, EMS closed-loop safety logic, ensures system safety
Precision liquid cooling temperature control design achieves long-term stability, with temperature difference among different cells being ≤3°C
Intelligent switching strategies for different scenarios: peak shaving, capacity management, dynamic capacity expansion, renewable energy consumption, and planned curve response
Local and cloud monitoring are integrated, enabling rapid digital diagnosis and intelligent automatic inspection

Independent energy storage power station
As an independent market entity, it participates in electricity market transactions. It can provide peak shaving (discharging during peak load periods) and frequency regulation (rapid response to grid changes)
Earn service revenue through various auxiliary services such as frequency fluctuation and standby. Multiple similar integrated cabinets can be connected in parallel to quickly build a 10MW/20MWh system
Even power stations of the megawatt-hour level
Microgrid and distributed energy applications constitute the core of microgrid: combined with distributed photovoltaic systems, small wind turbines, diesel generators, etc., they form self-sufficient microgrids for islands, remote outposts, and areas without electricity, providing stable and continuous power. Improve the penetration rate of distributed energy: in urban distribution networks, they alleviate issues such as reverse power flow and voltage violations caused by the large-scale integration of distributed photovoltaic systems.
Photovoltaic/wind power with energy storage: Plan tracking: Assist power stations in operating according to preset power generation curves.
Smooth output: Suppress the randomness and volatility of wind and solar power generation, ensuring that the power output of the plant aligns more closely with the grid dispatching requirements.
Abandoned power consumption: Storing wind and solar power that is abandoned due to insufficient grid consumption capacity, and releasing it when it can be delivered
Industrial and commercial park/factory peak-valley arbitrage: Charging during off-peak periods such as at night or during lunch breaks, and discharging during peak electricity price periods during the day or in the evening, directly saving on high electricity bills. This is its most direct and common profit model. Demand management: Real-time monitoring of enterprise electricity load, when the power consumption is about to exceed the "maximum demand" contracted with the grid, the energy storage system quickly discharges to "cut the peak", avoiding high demand electricity penalty fees. Power quality management: Mitigating issues such as voltage sag and fluctuation, ensuring stable operation of precision production equipment. Emergency backup power supply: In the event of planned power outages or grid failures, seamlessly switching to supply power to critical loads, ensuring production continuity
