Stackable Home Battery
Battery modules that stack on a base, so capacity grows one module at a time.
- Rating
- 5.1–35 kWh
- Versions
- 5.1 kWh 48 V module · 20/25/30/35 kWh HV · 204–409 V 50 Ah
Best for: Homes and small businesses that expect to expand storage.
- Add capacity module by module
- Low-voltage and high-voltage versions
- Floor-standing, no wall fixing
- LiFePO4 chemistry
A stackable battery starts with a base and one or more modules; more modules are added on top as consumption grows. It suits buyers who want to start small without replacing the battery later.
Low-voltage or high-voltage?
| Version | Voltage | Capacity |
|---|---|---|
| Low-voltage module | 48 V class | 5.1 kWh per module |
| High-voltage stack | High voltage | 20, 25, 30 or 35 kWh |
| High-voltage 50 Ah system | 204 / 256 / 307 / 358 / 409 V | 50 Ah, by number of modules |
Low-voltage stacks pair with 48 V hybrid inverters, common in homes. High-voltage stacks pair with high-voltage hybrid inverters, which run more efficiently at higher power — useful for large homes and small commercial sites.
Tell us your inverter and we confirm which stack it supports.

Frequently asked questions
Can I mix old and new modules?
Modules of the same version can be added later. Mixing very old and new modules can limit the stack to the weakest module, so we advise expanding within the first years.
Low-voltage or high-voltage — which is better for a home?
Low-voltage (48 V class) stacks are the most common and work with many hybrid inverters. High-voltage stacks suit larger homes and small businesses with high-voltage hybrid inverters. Your inverter decides.
How much space does a stack need?
A footprint about the size of the base, with height growing with each module. Leave clearance around it for ventilation and service.
Which certificates do your home storage products have?
It differs by model. Ask for the certificate list of the exact model with your quotation — we send copies, and you can check them with the issuing body. Lithium batteries always ship with a UN38.3 test summary.
Can I order a sample before a larger order?
Yes. Distributors and installers often start with one or two units to test with their inverters and customers. Lithium samples travel by sea or by an air service that accepts dangerous goods, so allow for that in the timeline.
