AI-W5.1-B, one 5.12 kWh module for a flat or a backup circuit

A single module, 569 mm tall and 74.5 kg, holding 5.12 kWh with 4.6 kWh of that usable. It is the smallest step into storage and the one that fits under a stair or in a utility room without rearranging anything. Start here if the aim is riding through the evening peak or a short outage on essential circuits, then add modules later on the same footprint.

Modules: 1 x 5.12 kWh · Stack height: 569 mm · Weight: 74.5 kg · Usable energy: 4.6 kWh

AI-W10.2-B, two 5.12 kWh modules stacked to 850 mm for a family home

Two modules in one column: 850 mm tall, 127.5 kg, and 9.2 kWh usable at the recommended 90% depth of discharge. The second module adds no floor area at all, since the cabinet stays 720 mm wide and 255 mm deep. This is the usual size for a house that wants overnight cover for a fridge, lights and one air conditioner rather than a short outage only.

Modules: 2 x 5.12 kWh · Stack height: 850 mm · Weight: 127.5 kg · Usable energy: 9.2 kWh

AI-W15.3-B, three 5.12 kWh modules at 1,131 mm for whole-home backup

Three modules, 1,131 mm tall and 180.5 kg, giving 15.36 kWh nominal and 13.8 kWh usable. At this height the stack is still below eye level and two people can build it module by module. It is the point where a home battery stops being a backup box and starts carrying a full evening of ordinary household use on its own.

Modules: 3 x 5.12 kWh · Stack height: 1,131 mm · Weight: 180.5 kg · Usable energy: 13.8 kWh

Model code: AI-W5.1-B-ESS-W15.3-B

AI-W20.4-B, four 5.12 kWh modules and 20.48 kWh for a large villa

Four modules stacked to 1,412 mm, weighing 233.5 kg, for 20.48 kWh nominal and 18.4 kWh usable. The floor under it has to be solid and level, because the whole mass rests on a 720 by 255 mm footprint. It suits a large house running several air conditioners overnight, or a small business holding its own load through an evening tariff peak.

Modules: 4 x 5.12 kWh · Stack height: 1,412 mm · Weight: 233.5 kg · Usable energy: 18.4 kWh

Model code: AI-W5.1-B-ESS-W20.4-B

AI-W25.6-B, five 5.12 kWh modules, 25.6 kWh in a 1,693 mm column

Five modules, 286.5 kg, standing 1,693 mm tall, for 25.6 kWh nominal and 23 kWh usable. The step from four modules to five adds 281 mm of height and 53 kg, the same increment as every module before it, so an installer can predict the finished column to the millimetre. Pick it where a long stretch of stored energy matters more than floor space.

Modules: 5 x 5.12 kWh · Stack height: 1,693 mm · Weight: 286.5 kg · Usable energy: 23 kWh

Model code: AI-W5.1-B-ESS-W25.6-B

AI-W30.7-B, six 5.12 kWh modules for the full 30.72 kWh stack

The tallest column the AI-W allows: six modules, 30.72 kWh nominal, 27.6 kWh usable, 1,974 mm tall and 339.5 kg. Nothing goes above this in one stack, so check ceiling height and door width before ordering. It suits a house that runs off its own solar most of the year, or a shop shifting a whole day of daytime billing into stored energy.

Modules: 6 x 5.12 kWh · Stack height: 1,974 mm · Weight: 339.5 kg · Usable energy: 27.6 kWh
