Product Features of 100kW Battery Storage

The BESS-M 100-217-120 100kW battery storage system packs storage, power conversion, and protection into one outdoor-ready cabinet:

All-in-one design: a high degree of integration that simplifies transport, installation, and commissioning.
Modular design: optional modules of different sizes, with PCS output of 40kW, 60kW or 100kW and up to 5 PCS in parallel.
Grid-connected and off-grid operation: built-in STS with a switching time of ≤ 10ms.
Optional MPPT solar controller: with 4 MPPTs, 200V–950V range and up to 120kW PV input, the cabinet works as a 100kw solar battery solution.
IP54 fire and explosion-proof housing: aerosol fire module for added safety.
Patented air duct design: dry self-cooling keeps the battery cell temperature difference to 3–5°C.
Wide operating range: -30 ~ 60°C (derating above 45°C) and altitudes up to 4000m (derating above 2000m).
Easy monitoring: 7-inch resistive touch screen; certified to CE, IEC62619 and UN38.3.

Commercial Applications of 100kW Battery Storage

Commercial and industrial sites use 100kW battery storage to store solar energy by day and release it at night, cut diesel runtime, and keep critical loads online. Combined with a diesel generator in a pv diesel generator hybrid system, the battery absorbs short-term load swings so the generator can run in an efficient, stable range.

PV-ESS-Diesel microgrid — PV + energy storage + diesel generator: a tiered, multi-energy microgrid

Applications & Use Cases

Remote and off-grid sites: reliable power where no city grid is available, including an island microgrid for communities, resorts, and infrastructure.
Solar self-consumption: daytime storage and nighttime release to maximize on-site PV use.
Diesel fuel reduction: shorter generator start-up time, lower fuel dependence, and reduced transport and maintenance costs.
Critical load backup: uninterrupted supply during extreme weather and sudden load changes.
Power quality support: real-time frequency and voltage regulation and power smoothing for grid-like stable power.
