Overview

Two Ways to Build It

Battery storage only, or batteries and inverter-charger in one rack. Systems scale to 60 kVA, single or three-phase.

More Load, Same Grid

Stored energy covers the peaks, so you can add EV charging or new equipment without a supply upgrade.

Every Source, One Platform

Solar, wind, hydro, generator, grid and hydrogen or methanol fuel cells, all managed automatically.

Storage That Scales

Up to 40 kWh of LiFePO4 in each rack. Add racks in parallel as demand grows.

Eyes On It, Remotely

Touchscreen control on the rack and live monitoring online, as standard.

Indoors or Outdoors

36U racks for plant rooms and garages, or a 36U IP55 galvanised field cabinet outdoors. Air conditioning on request.
