BATTERY ENERGY STORAGE SYSTEMS (BESS)
WS-L5000 + WS-MV5000 — 5 MW / 5 MWh containerized BESS
Country: China · Model: WS-L5000 + WS-MV5000
A 5 MW / 5 MWh containerized BESS made of the WS-L5000 battery container and the WS-MV5000 power conversion unit. The 20 ft container holds 5,016 kWh, and system efficiency reaches 94.5 %. The set connects straight to the medium-voltage grid, so it belongs at a substation, next to a large PV plant or on a factory site.

Description
The batteries in the WS-L5000 are liquid-cooled, which is what lets 5,016 kWh fit into a standard 20 ft footprint without overheating the cells. The WS-MV5000 houses the PCS, rated at up to 99 % efficiency, and the medium-voltage transformer in one unit. No separate transformer kiosk is needed on site, as the cable from the unit runs straight to a 12–36 kV, 50/60 Hz switchgear bay. The gap between 99 % PCS efficiency and 94.5 % system efficiency is taken up by the battery, the transformer and the container auxiliaries, cooling included. The MV5000 enclosure is IP54, and its C5-M corrosion protection is rated for marine and heavily polluted industrial air. The set runs 2-hour or 4-hour discharge applications.
How to choose
Start by deciding which duty the site needs. A two-hour discharge suits peak shaving and ancillary service markets, while four hours suits shifting daytime PV output into the evening. Check your distribution grid voltage against the 12–36 kV range and the transformer version before ordering. When the need is hundreds of kilowatts rather than megawatts, the MC-L522 cabinet with 522.5 kWh and 250 kW or the MC-L430 / MS-L430 with 430.08 kWh and 200 kW makes more sense.
