Frequently Asked Questions

1. What are the main applications of the 261kWh energy storage system?

It is mainly used for industrial and commercial peak shaving, demand response, backup power for critical facilities, and improving self-consumption of solar energy.

2. Why use liquid cooling instead of air cooling for the battery?

Liquid cooling provides better temperature uniformity (within +/- 3 degree C), extending battery cycle life and enhancing safety during high-power operation.

3. Can multiple units be connected in parallel?

Yes, the system supports multi-cabinet parallel connection on the AC side to scale up to meet larger energy demands.

4. What is the estimated lifespan of the 314Ah LFP cells?

Under standard operating conditions, the cells are designed for more than 6,000 to 8,000 cycles at 80% DOD.

5. Is the system compatible with existing solar inverters?

Yes, our AC-coupled design allows easy integration with any existing PV system without changing the original solar setup.

The system is "plug-and-play" ready, requiring only AC connection and communication commissioning upon arrival at the site.

7. How does the EMS handle complex energy trading?

Our smart EMS supports AI-driven strategies for arbitrage, demand response, and solar forecasting, maximizing the ROI of your 261kWh investment.
