51.2V 100Ah module / 5 kWh
Stackable Lithium Batteries
51.2V modules that stack from 5 kWh to 30 kWh, 6000+ cycles, RS232, RS485 and CAN communication.
The stackable range exists for one reason: the household that wants 10 kWh today and 25 kWh in three years, without a second inverter or a second wall. One module is 51.2V 100Ah, or 5 kWh. Stack two for 10 kWh, three for 15 kWh, and on up to six modules and 30 kWh, with a base and a controller carrying the stack. Four products in the range cover the popular capacities directly, including a 200Ah module for installs that want fewer, larger units.

The problem
What This Group Is Built To Solve
Fixed-capacity home storage forces a guess. Size it for today's load and the customer is back in two years; size it for the future and the first invoice is too big to sign. A stack turns capacity into a line item the customer can add later: same footprint, same inverter, same commissioning, one more module.
Who buys these
Who This Range Is For
Solar Installers With Phased Projects
Selling a first phase that the customer can extend without a second site survey.
Distributors Serving Mixed Housing
One SKU that covers apartments and large homes by changing the module count.
Off-Grid System Builders
Where the load grows with the property and the battery has to follow it.
Why these
What Makes This Range Different
5 kWh Per Module, Six Modules Deep
5, 10, 15, 20, 25 and 30 kWh from one part number, stacked rather than rewired.
Three Communication Protocols
RS232, RS485 and CAN on the stackable range, which is what keeps it compatible with mainstream hybrid inverters.
6000+ Cycles On Grade A Cells
The same cell and BMS specification as the powerwall range, in a format that grows.
Moves Without A Crane
Around 50 kg per module. A stack can be carried in and assembled in place instead of arriving as one immovable cabinet.
Application
Where These Packs Are Used
- Phased residential storage that grows with the household load
- Off-grid homes stepping up from a small starter bank
- Small commercial backup in shops and workshops
- Time-of-use tariff shifting where payback decides the module count
- Solar self-consumption on a hybrid inverter
- Replacement of an ageing lead-acid bank in stages
Applications
Sectors That Specify This Group
Residential Solar Storage
Powerwall, stackable and rack mount 51.2V storage for homes running solar self-consumption, tariff shifting or full off-grid.
Commercial And Industrial Energy Storage
Liquid-cooled 215 kWh and 232 kWh all-in-one cabinets, plus 51.2V modular banks for smaller commercial sites.

How To Size A Home Battery Without Guessing
Working from evening load rather than array size, choosing between 5, 10, 15 and 30 kWh, and leaving an expansion path.
FAQ
Stackable Lithium Batteries Questions
How many modules can I stack?
Up to six, which gives 30 kWh from 5 kWh modules. The published family runs 5, 10, 15, 20, 25 and 30 kWh.
Do all the modules have to be bought at once?
No. That is the point of the format. Add modules later, provided they are the same model and the base and controller are sized for the final stack - tell us the target capacity at the first order and we will specify it that way.
Stackable or wall mount - which should I quote?
Wall mount where the capacity is settled and the wall is free. Stackable where the customer is likely to expand, or where the floor is easier to use than the wall. Both are 51.2V, so the inverter side of the design does not change.
What communication does it support?
RS232, RS485 and CAN are published for this range. Send the inverter model with the enquiry and we will confirm the protocol match.
How heavy is a module?
About 50 kg for the 5 kWh module and about 53 kg for the 200Ah module, per the published specifications. Two people can place one without lifting equipment.
Which certificates apply?
MSDS, UN38.3, CE, ROHS and UL are listed for the stackable range. Ask for the copies covering the exact module you order.
