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.
Energy arbitrage
Charge in low-price blocks and discharge into evening peaks. 8,000-cycle LFP and liquid cooling built for daily cycling.
Frequency response & ancillary services
Sub-100 ms full reversal and < 200 ms 0–100% ramp at block level, with IEC 61850 plant control.
Renewable firming
Co-locate with solar or wind to shape output, firm capacity and reduce curtailment at the point of interconnection.
Black start & islanding
Block-level black-start capability with DG-backed auxiliaries, subject to the approved single-line design.
