Modular Liquid-Cooled Energy Storage System
210kW / 836kWh Modular Liquid-Cooled Battery Energy Storage Cabinet
Galaxy 836L is a modular liquid-cooled commercial & industrial energy storage cabinet that significantly improves energy density per unit area. It integrates high-density lithium battery storage, PCS, an in-house EMS built on Siemens PLCs, high-voltage box, VSG grid-forming, fire safety and intelligent thermal management — delivered as a fully prefabricated, plug-and-play unit.
210 kW / 836 kWh
Why Galaxy 836L ?
Galaxy 836L features an intelligent fire protection system with combustible gas detection, ventilation, and aerosol fire suppression, complying with NFPA-855, NFPA 69 and NFPA 68. Backed by 0 battery degradation in the first year and smart liquid cooling for stable cell performance, this system ensures comprehensive safety and stable operation of the energy storage system.
The in-house EMS is built on Siemens PLCs with PROFINET IRT hard real-time control — µs-level synchronization, jitter under 1µs, and up to 100 cabinets in parallel on a bandwidth-isolated IRT bus. It enables complete remote operations including commissioning, maintenance, upgrades and fault handling, while native FCR support lets customers switch to high-demand frequency regulation via software with zero hardware replacement.
Galaxy 836L is engineered for rapid, hassle-free deployment. Fully prefabricated modules allow easy installation and 3-hour fast commissioning for rapid deployment and quick ROI. Each cabinet weighs less than 7 tons, a 2 m² footprint holds 0.83 MWh, and up to 4 units (3.34 MWh total) ship within a single 40-foot HQ container. An external centralized liquid cooling solution reduces costs and facilitates future maintenance.
690V / 800V output perfectly matches transformerless string PV inverters for seamless system integration. The 800V option eliminates the need for step-up transformers and significantly reduces infrastructure costs. Adopting a VSG grid-forming algorithm, the system provides virtual inertia and damping to suppress resonance and oscillation, making it optimal for weak grids and 800V PV-storage systems.
