The PowerStack is designed for the 250 kW consumer market, which is a portfolio with battery capacity ranging from 500 kWh to 1 MWh, available for 2 hour and 4 hour applications.
Energy storage in the commercial and industrial (C&I) segment is poised to grow over the next decade. It is estimated that by 2030, the annual growth of the global C&I energy storage market will exceed hundreds of billions of US dollars. The United States will be one of the largest incremental markets.
C&I energy storage gains political and economic support
What factors are driving the adoption of the C&I Energy Storage System (ESS) in the United States?
On the one hand, the growing popularity of renewables comes with volatility and intermittency, which leads to potential risks and operational problems for the grid. ESS coupled with renewable energies contribute to grid stability. In addition, power outages caused by natural disasters and imbalances between supply and demand lead to substantial economic losses, and the SSE also plays a role in the increased interest in backup power.
On the other hand, the cost of electricity for C&I demand is relatively high in the United States. Driven by incentives such as time-of-use electricity pricing and favorable updated rules on net metering, ancillary services, federal and state subsidies, the C&I ESS is increasing revenue.
Cost effectiveness, safety, integration, and operation and maintenance (O&M) costs are always top concerns for stakeholders when choosing an ideal C&I ESS. Sungrow, the world’s leading inverter and ESS solution provider, has launched its competitive C&I liquid-cooled ESS, the PowerStack.
Complete energy storage solution
The PowerStack is designed for the 250 kW consumer market, which is a portfolio with battery capacity ranging from 500 kWh to 1 MWh, available for 2 hour and 4 hour applications. The solution combines lithium-ion batteries, a power conversion system (PCS), a battery management system (BMS) and a fire suppression system (FSS), streamlining transport, installation and maintenance. operation and maintenance. The PowerStack has been jointly pre-ordered so that all parameters are set before leaving the manufacturing base, reducing on-site commissioning time and ensuring quick returns for project owners.
Thanks to liquid cooling technology, the PowerStack comes with a lower battery temperature difference, extending battery life and greatly improving charging and discharging efficiency. Compared with the conventional air-cooling design, the liquid cooling system also significantly reduces thermal management power consumption.
Automatic state-of-charge (SoC) calibration and automated coolant refill significantly reduce operation and maintenance (O&M) costs.
Safety is the top priority in battery system technology. Sungrow’s PowerStack offers comprehensive security design at the cell, electrical and system levels. AI-assisted cell monitoring technology performs high-accuracy online calculation of cell status and provides early warnings to prevent thermal runaway. Four layers of overcurrent protection and arc flash protection mitigate electrical hazards. Patented hose connectors, IP65 module design, one-way breather valve and drip catcher ensure system safety in multiple aspects.
Sungrow offers combustible gas detection and venting system as well as water-based suppression system as standard FSS configuration in USA, which meets NFPA855/NFPA69/NFPA15 requirements.
Sungrow is an early entrant into the energy storage space with 3 GWh deployed in 2021. Its liquid-cooled ESS PowerStack exceeds demand for exceptional flexibility and performance. With the growing interest in using ESS to provide value-added services, the solar-plus-storage community in some US states is becoming another rise within the industry. Sungrow is one of the few companies to offer both PV inverter and ESS solutions. The company’s complete solar-plus-storage solution, optimized for C&I markets, will ensure lower electricity pricing and energy security, while helping to tackle the climate crisis.
