Description
Decentralized container-level power regulation.
GoodWe GW208.9-BAT-LCD-G10 is a 208.9 kWh liquid-cooled commercial storage container with an integrated bidirectional DC-DC converter and 314 Ah LFP cells, engineered for multi-container parallel scaling up to 1,044 kWh without circulating currents.
Integrated Bidirectional DC-DC Optimization
Built-in DC-DC power stage regulates container voltage dynamically, enabling parallel expansion without master-slave capacity penalties.
208.9 kWh Liquid-Cooled High-Density Storage
Delivers utility-scale storage capacity with 314 Ah prismatic LFP cells in a compact, pad-mounted enclosure.
Precision Closed-Loop Liquid Cooling
Advanced coolant circulation keeps cell-to-cell temperature differentials strictly under 2.5 °C under continuous 0.5C cycling.
Multi-Container Parallel Scaling (Up to 1,044 kWh)
Parallel link up to 5 containers seamlessly without external central combiner switchgear.
More product details
In traditional multi-container battery banks, slight voltage differences between cabinets cause dangerous circulating currents and uneven cell aging. The LCD series integrates an active DC-DC converter into each container.
- Active bidirectional DC-DC converter regulates output voltage independently across a 600–900 V window.
- Allows parallel mixing of containers with different states of health without dragging down system capacity.
- Eliminates external central DC combiner hardware and heavy coupling switchgear.

Extending battery lifespan with active liquid thermal regulation.
Closed-loop liquid coolant channels beneath each 314 Ah cell group maintain uniform thermal distribution, maximizing calendar life and safety. Cell-to-cell temperature variance maintained strictly within ≤2.5 °C under continuous 0.5C charge/discharge rates. Multi-sensor aerosol fire suppression, combustible gas detection, and emergency pressure relief vents. IP55 heavy-duty C4/C5 anti-corrosion rated enclosure for harsh outdoor environments (-30 to +55 °C).
Runs 700 to 1000 V operating voltage
Four 314 Ah packs connect in series at 665.6 V nominal. The 700 to 1000 V window targets high-voltage C&I power conversion.
Holds 93 percent round-trip efficiency
Liquid cooling stabilizes cell chemistry across 10000 cycles at 100 percent depth of discharge. Continuous 0.6P cycling is fully supported.
Fits a 1050 x 2025 x 1565 mm enclosure
Cabinet mass is rated at 2105 kg or less. CAN communication manages battery parameters with the paired hybrid inverter.

What is the main operational difference between the LC and LCD container models?
LCD includes an internal bidirectional DC-DC converter for multi-container parallel scaling. * GW208.9-BAT-LC-G10: Direct DC battery container. Best for single-container installations or systems with external DC-DC PCS units. * GW208.9-BAT-LCD-G10: Features an integrated bidirectional DC-DC converter in each container, regulating voltage independently so up to 5 containers can parallel on a shared bus without circulating currents.
What are the physical dimensions and weight of the LCD container?
Approx. 1030 × 1400 × 2325 mm; ~2,700 kg total weight. The container measures 1,030 mm wide × 1,400 mm deep × 2,325 mm high and weighs approx. 2,700 kg. It is designed for direct outdoor pad mounting on a reinforced concrete slab.
