Extending battery lifespan with active liquid thermal regulation.
GoodWe GW208.9-BAT-LC-G10 is a 208.9 kWh liquid-cooled commercial outdoor storage container delivering 665.6 V nominal voltage with 314 Ah automotive-grade LFP cells, engineered for industrial microgrids and megawatt-scale solar farms.
208.9 kWh High-Density Containerized Storage
Consolidates utility-grade storage capacity into a compact outdoor pad footprint (approx. 2,600 kg).
Industrial Closed-Loop Liquid Cooling
Precision liquid coolant circulation ensures uniform thermal distribution (≤2.5 °C variance), extending battery calendar life.
314 Ah Automotive-Grade Prismatic LFP Cells
Large-format cell architecture reduces internal interconnect resistance, lowering heat generation and boosting efficiency.
665.6 V High-Voltage Operating Bus
Seamlessly matches 100 kW to 250 kW commercial and utility-scale central PCS units.
More product details
Air-cooled battery containers suffer localized hot spots during high-rate summer cycling, accelerating cell degradation. The GW208.9-BAT-LC-G10 circulates liquid coolant directly through thermal plates beneath each 314 Ah cell group.
- Maintains cell-to-cell temperature differentials strictly under 2.5 °C across the entire 208.9 kWh container.
- Extends battery calendar life by over 30% compared to conventional air-cooled commercial cabinets.
- Integrated chiller/heater unit maintains optimal 20–25 °C cell temperatures across extreme ambient environments (-30 to +55 °C).

GoodWe BAT-C 208.9-261.2 kWh datasheet (EMEA, EN)Product questions
What is the benefit of 314 Ah liquid-cooled cells over smaller air-cooled cells?
Higher volumetric energy density, fewer internal joints, and superior thermal uniformity. Large-format 314 Ah prismatic cells drastically reduce the total number of series/parallel electrical joints inside the battery, lowering internal contact resistance and failure points. Direct liquid cooling maintains cell temperatures within ≤2.5 °C variance, preventing localized hot spots that cause premature cell degradation in air-cooled racks.
What are the physical dimensions and weight of this container?
Approx. 1030 × 1400 × 2325 mm; ~2,600 kg total weight. The container measures 1,030 mm wide × 1,400 mm deep × 2,325 mm high and weighs approx. 2,600 kg. It is designed for direct outdoor pad mounting on a reinforced concrete slab.
