These are categorized into three main types depending on your project requirements: Top integrators: these are companies like Sungrow, Tesla, and Fluence that design complete, scalable turnkey systems combining batteries, power conversion, and software controls. Tier-1 cell manufacturers: these are giants like CATL, BYD, and LG Energy Solution that supply the underlying LFP and NMC cell chemistry and modules. Specialized solution providers: these are integrators like Sunpal that deliver tailored commercial, industrial, and utility-scale systems to maximize ROI with flexible, high-quality components.

Our 1MW-5MW Battery Energy Storage Systems (BESS) are versatile energy solutions designed for Utility-Scale and C&I (Commercial & Industrial) projects. Powered by advanced Energy Management Systems (EMS) and high-voltage Lithium batteries, they are engineered to maximize ROI and energy security in four key areas:

1. Peak Shaving (Cost Reduction)
This is the most common application for reducing operational expenses.
How it works: The system automatically detects when energy usage hits "peak" rates. It discharges stored energy during these expensive windows and recharges when grid prices are low.
Benefit: This drastically lowers demand charges on electricity bills, making it essential for factories and large commercial facilities.

2. Energy Trading (Arbitrage)
Turn your energy storage into a revenue-generating asset.
How it works: Leveraging the smart optimization capabilities of our EMS, the system can participate in electricity markets. You can buy electricity when prices are negative or low, store it, and sell it back to the grid when prices spike.
Benefit: Creates a new revenue stream through energy arbitrage and participation in ancillary service markets (like frequency regulation).

3. Backup Power (UPS & Resilience)
Ensure your operations never stop, even during grid failures.
How it works: The system features a Control Combiner Current Cabinet with integrated UPS (Uninterruptible Power Supply) technology. In the event of a blackout, the Megarevo MPS Hybrid Inverter switches seamlessly from grid-tied to battery power. With Black Start Capability, the energy storage system can function as an independent voltage source, allowing it to directly start up a local microgrid without relying on the external grid in the event of a complete grid outage or system shutdown — quickly restoring power to critical loads.
Benefit: Provides critical energy security for data centers, hospitals, and manufacturing lines, preventing costly downtime.

4. Microgrid Generation
Create an independent energy island capable of operating without the main utility grid.
How it works: By combining our Sunpal N-type Bifacial Solar Panels with the BESS, you can generate and store your own power. The system’s isolation transformer ensures stable off-grid operation, allowing it to function as the primary power source for remote areas or islands.
Benefit: Achieves total energy independence and supports sustainable, decentralized power networks.

Yes. The system can be integrated with existing PV plants to enhance energy storage capacity and improve power management.

A standard 1MW 2MWh energy storage system has a market reference starting price of approximately $360,000 USD, with the final cost varying based on air-cooling vs. liquid-cooling technology, fire safety configuration, and brand customization requirements.
