AMPROTEQ
Liquid-cooled lithium iron phosphate in two architectures. AC integrated systems carry their own converter and deliver 400 V AC. DC blocks hold only the battery and hand 1 120–1 500 V DC to a PCS or an MV skid sized to the connection.
The PCS, liquid cooling, fire detection and suppression, switchgear and the Solaris™ controller ship inside the battery enclosure, integrated and tested before dispatch. The output is 400 V three-phase: land it on the site’s LV board, or step it up on a transformer for a medium-voltage connection.
The entry system: 1 044 kWh of liquid-cooled LFP and a 500 kW PCS at 400 V in a 10 ft container. One slab, one connection, one unit, and a plant grows in 1 MWh steps.
Two megawatt-hours in a 20 ft high-cube, in two builds: 1 MW to carry both tariff peaks on stored energy, or 500 kW for a four-hour discharge from the same battery.
A DC block is the battery and nothing in front of it: liquid-cooled LFP racks, battery management, cooling and fire protection in a 20 ft high-cube, delivering 1 120–1 500 V DC. The conversion is supplied separately, as string PCS or an APEX MV skid, so it is sized to the connection and the duty rather than to the container.
The most specified block for commercial and mid-industrial sites paired with a 1 MWp-class solar array.
Sized for a large industrial site carrying both tariff peaks on stored energy, with headroom for load growth.
Utility density in a standard footprint. Two DC buses, matched one-to-one to an APEX X2500: 2.5 MW and a single MV connection.
The largest block in the range: the replication unit for utility and IPP plants where land and cable routes set the limit.
A 314 Ah lithium iron phosphate prismatic cell — the safest large-format chemistry in commercial service. Serialised, traceable, tested before it leaves the line.
Cells are welded into a series string and clamped in an aluminium housing, with a liquid-cooling cold plate beneath them and cell-level voltage and temperature sensing on top.
Packs stack into a rack and connect in series through a cluster controller with its own contactors, fusing and pre-charge. Each cluster is an independently managed DC source.
A standard 10 ft high-cube. Four clusters on a shared coolant manifold, four bidirectional PCS modules, the isolation transformer and the Solaris™ controller, with the liquid-cooling unit behind the louvered end door. Assembled and burned in at the factory.
Site scope is a plinth, cable trenches, earthing and commissioning. Nothing arrives on your slab as a kit of parts. Separations and clearances follow the installation manual and NFPA 855 guidance.
The block’s 400 V output lands on a factory-tested skid carrying the step-up transformer, ring main unit, protection relays and metering. One skid serves several blocks.
The point of connection is the utility’s; the interface is ours — grid-code studies, reactive capability, ride-through and the connection application, built to NRS 097-2-1.
Half a megawatt in either direction, dispatched every four seconds by Solaris against the tariff calendar, the notified maximum demand and the reserve you hold for the day the grid goes away.
The same chain as the story above, hardware by hardware: 1 040 prismatic cells in twenty liquid-cooled packs, five packs to a cluster, four clusters to the block, with the cooling unit and power conversion in the same container.
Visualisations of the A1000
Cell life is governed by temperature, and by how evenly that temperature is spread. Our integrated liquid-cooling system runs a cold plate through every module layer and holds deviation to 3 °C — against the 12–18 °C typical of forced-air compartments. Toggle the cooling mode and watch the pack.
This is the actual coolant circuit inside our containers. A supply header and a return header run the length of the rack line, with an individually valved branch to every single module position — not a shared plenum, not a compartment full of moving air.
That topology is why the pack holds 3 °C. Every module sees coolant at the same temperature, at the same flow rate, regardless of where it sits in the string. Redundant pumps and frequency-converted drives track the thermal load rather than running flat out, so auxiliary consumption stays low.
A pack ages at the rate of its worst cell, not its average. Compressing the spread from 15 °C to 3 °C is what turns a warranty schedule into something a lender will underwrite.
Coolant enters at 18 °C, passes through a serpentine channel in direct contact with every module, and returns at 23 °C. Frequency-converted pumps track load rather than running flat out.
Against an air-cooled equivalent in the same ambient conditions — and materially lower auxiliary consumption, because you are not conditioning a whole compartment of air.
We use one chemistry and we use it properly. LFP is the safest lithium chemistry in commercial production, the most mature supply chain in the world, and with liquid cooling it delivers the cycle life a twenty-year commercial model needs.
The phosphate cathode is chemically stable at temperatures where other lithium chemistries begin to break down. Higher thermal runaway threshold, no oxygen release, and a far more benign failure mode — which is what your insurer and your fire engineer will ask about first.
To 70% state of health at one full cycle a day and 98% depth of discharge — nineteen years of daily cycling; over 10 000 at 80% depth. Measured, not modelled: the retention lab below is the cell manufacturer’s own tabulated test set, and because we hold the pack within 3 °C the cells actually reach it.
Iron and phosphate rather than scarce, price-volatile metals. That means a cost curve that keeps falling, a supply chain that is not a single point of failure, and a materially cleaner sourcing story for your ESG reporting.
The cell manufacturer’s tabulated 20-year test set, transcribed without adjustment: state of health year by year across ten dispatch duties at 98% depth of discharge, plus 90% and 80% depth at three duties. Not an illustrative shape with a specified end point. Storage is sized with the end of the term in mind, and augmentation is priced into the model from the start.

DC block power is at 0.5C through the paired converter; see converter pairing.
Duration is a commissioning choice, not a different product. The container, the cells and the cooling are identical; only the conversion rating and the dispatch envelope change.

The systems differ in capacity, not in design. Chemistry, DC architecture, protection, cooling, controls and compliance are identical across the range, which is what makes a site upgrade a question of adding blocks rather than requalifying a platform.
