500 kW / 514 kWh (TOBOR BESS 500). Four paralleled 125 kW PMs on a two-string 314 Ah LFP battery — the typical size for steel, textile and pharma plants cutting maximum demand and diesel hours, and for EV fleet depots on a constrained connection.

Catalogue values. *Cycle capability depends on depth of discharge, C-rate, temperature and end-of-life criterion. Peak PM efficiency is not whole-system round-trip efficiency. Usable energy and runtime depend on permitted DoD, conversion losses and auxiliaries. Final ratings and compliance follow the approved project-specific offer.
Where this size fits.
Peak-demand shaving
Clip maximum-demand peaks with EMS dispatch inside battery limits. Demand-charge savings are sized from your 15-minute interval data.
Solar self-consumption
Charge from surplus rooftop or ground-mount PV and dispatch it into evening and night shifts instead of exporting at low rates.
DG-hours reduction
Carry critical loads through outages and cut generator runtime. Battery capacity is sized to the outage profile and priority loads.
BESS-buffered EV charging
Run TOBOR DC fast chargers on a smaller grid connection — the battery covers the charging peaks, the EMS coordinates both.
