Up to 1.28MW DC charging for trucks, buses and heavy plant
Drop and Go in a 20ft footprint, in under two minutes
Parallel units without limit for larger sites

Proven

Data centres, modelled

A MAX1500 runs a 1.26MW hall from an existing 500kW supply, bridging the wait for a new connection without diesel.

£200k

a year saved against diesel bridge power

Where it is used: Data centres, truck and bus depots, major infrastructure, utilities, industrial sites

What it does

Everything it can do, and how you can have it

On-grid · Stationary

Battery as a buffer

Charge off-peak or from solar.
Boost peak power above your limit.
Back up the site in under 40ms.
Earn from grid flexibility markets.

Off-grid · Mobile

Battery as a generator

Charge from DC, a MAX or a generator.
Power quietly, zero local emissions.
Top up from a generator if needed.
Save fuel, run hours and emissions.

EV charging

Integrated, grid-tied or off-grid

DC 180, 240, 480, 640kW or 1.28MW (1.28MW on High Power). Two outlets, buffer or direct. DC recharging (125kW) lets MAX top up from any public or depot DC charger.

Drop and Go

Deployed in minutes

Lowered from a standard hooklift truck in under two minutes, or lifted from the top. Permanent, semi-permanent or fully mobile. Classified UN3536 for simple transport.

Power control

Advanced energy and power transfer

PackFlex

Each pack runs through its own inverter, so the system keeps going if one goes offline, and charges and discharges at once.

Standard

SyncFlow

Synchronises with the grid or a generator, transferring loads in under 40ms; peak shaving keeps a site within its limit.

Option

IsoCharge

Isolates sensitive loads from supply disturbances, with no back-feed. MAX carries demand while a small supply recharges it.

Option

IsoPass

Keeps critical loads powered if the system goes offline, routing supply straight to the load. Essential for live broadcast.

Option

PhaseFlex

Turns a single-phase connection into a stable three-phase output, enabling DC fast charging from even a small supply.

Usable capacity at 100% pack state of health; average delivered state of health is 94%. Any single or mixed chemistry can be specified, which affects total capacity; a single-chemistry LFP system reduces capacity by approximately 25%. The platform fee is a single payment covering the first three years from delivery and extends the warranty to 5 years. All specifications are subject to change without notice.
