FAQ
Why is LFP battery technology preferred for C&I energy storage?
LFP batteries offer excellent thermal stability, enhanced safety, longer service life, and lower total ownership costs compared with many other lithium battery chemistries.
Does the system support reactive power control?
Yes. The power factor can be adjusted from -1 leading to +1 lagging, allowing flexible grid support and power management.
Why is liquid cooling superior to forced-air cooling for a 125kW / 261kWh cabinet?
Liquid cooling delivers 20%+ longer battery cycle life, lower auxiliary power consumption, and superior cell temperature uniformity compared to air cooling. The closed-loop glycol liquid cooling system maintains cell-to-cell temperature differentials $\le 2.5^\circ\text{C}$ across all 261kWh LFP battery modules, preventing localized thermal hot spots, minimizing capacity degradation, and keeping total operating noise below 65 dB(A).
What is the system AC-to-AC Round-Trip Efficiency (RTE) for the liquid-cooled ESS cabinet?
The system achieves a high AC-to-AC Round-Trip Efficiency (RTE) of $\ge 90%$ under standard 0.5C charge/discharge rates. High RTE is sustained by combining ultra-low-internal-resistance 314Ah/280Ah LiFePO4 cells, a high-efficiency 125kW silicon-carbide (SiC)/IGBT PCS power conversion system, and energy-optimized liquid-cooling pumps that draw less than 3% auxiliary power during thermal-management cycles.
