125kW BESS: Specification and Applications
A 125kW BESS pairs a 125KVA three-phase bidirectional inverter with a 261kWh LiFePO4 battery bank. That combination serves industrial and large-commercial sites: manufacturing lines, cold storage, processing plants, data rooms and multi-building estates that cannot tolerate a supply interruption.
A 125kW BESS is normally deployed alongside rooftop or ground-mount solar and operates in peak-shaving mode during the day, then discharges into evening and night loads. Our 6MW 20MWh storage case shows the same architecture at utility scale.
What a 261kWh BESS can power
Usable energy of about 235kWh covers the critical loads of a mid-size facility through a typical outage window: refrigeration, lighting, IT, security and selected production circuits. At half its rated power the system runs for roughly 3.8 hours between charges.
Paired with solar, the battery shifts daytime generation into the evening peak and keeps critical circuits alive when the grid fails.
How to size storage for your site
Start from the critical load list (kW) and the hours of cover you need — not from the total site load. Energy (kWh) = critical kW × hours, adjusted for depth of discharge and reserve. Our team sizes the battery, PCS and protection against your outage pattern and tariff.
