The Pylontech OPTIM US L260-OMNI is a fully integrated energy storage system (BESS) with on-board PCS (inverter), designed for commercial, industrial and large-scale export applications. Each outdoor cabinet brings together the LFP battery, the PCS and liquid cooling in a compact, ready-to-connect 400 Vac format.
A single cabinet delivers 260 kWh and 125 kW. Connecting up to 6 cabinets in parallel reaches 1560 kWh and 750 kW, with no heavy civil works, for arbitrage, grid services, demand response, peak shaving and backup projects.
Why choose the L260 Omni?
- Integrated PCS: on-board 125 kW inverter, 400 Vac / 50 Hz output, simplified on-grid connection.
- Safe LFP chemistry: depth of discharge (DoD) of 98 % and a service life of more than 8500 cycles.
- Liquid cooling: performance and service life preserved over a range of −25 to 50 °C.
- High efficiency: round-trip efficiency >95 % at 0.5 C and a PCS CEC efficiency of 98 %.
- Designed for outdoor use: IP55 protection rating, aerosol fire suppression, C3 anti-corrosion (C5 optional).
- Modularity: from 1 to 6 cabinets in parallel, from 260 to 1560 kWh.
