Powerwall Lithium Batteries
Wall-mounted 51.2V home storage from 5 kWh to 30 kWh, 6000+ cycles, five-year warranty, IP54 on the wall-hung models.
Four packs covering the whole residential range: 5 kWh and 10 kWh hung on the wall, 15 kWh for a house with a heat pump or air conditioning, and a 30 kWh floor unit on wheels for properties where the solar array has outgrown a wall-mounted battery. All four use grade A 3.2V LiFePO4 cells with a smart BMS that handles overheating, over-charge, over-discharge, short circuit and cell balancing, and all four carry 6000+ cycles and a five-year warranty.

The problem
What This Group Is Built To Solve
Residential storage gets specified backwards. The installer sizes the battery to the inverter rather than to the evening load, the house outgrows it in a year, and expansion means a second system rather than a second module. Sike powerwall packs are all 51.2V, so capacity grows by paralleling modules on the same bus: two 15 kWh units make 30 kWh, four 30 kWh units make 120 kWh, and the inverter and the wiring stay where they are.
Who buys these
Who This Range Is For
Residential Solar Installers
Fitting storage to an existing PV array where the wall space and the inverter are already decided.
Distributors And Brand Owners
Buying wall-mount storage under their own label, with OEM cases and protocol lists to match the inverters they sell.
Off-Grid And Backup Projects
Farms, workshops and rural properties where the grid is unreliable and the battery carries the night.
Why these
What Makes This Range Different
One Voltage Across The Range
Every powerwall pack is 51.2V, so a 5 kWh install and a 30 kWh install use the same inverter settings and the same expansion logic.
Parallel Expansion Rather Than Replacement
Add modules as the load grows. The 30 kWh unit parallels to 60, 90 and 120 kWh; the smaller units stack the same way.
Smart BMS With Cell Balancing
Overheating, over-charge, over-discharge, short circuit and balancing protection on every pack, which is what keeps a six-thousand-cycle claim honest.
Five-Year Warranty And 10+ Year Service Life
The published warranty is five years with a 10+ year service life expectation, on packs rated 6000+ cycles.
Application
Where These Packs Are Used
- Residential solar self-consumption and evening load shifting
- Backup power for homes on an unstable grid
- Off-grid houses and rural properties
- Time-of-use tariff arbitrage where the price spread pays for the battery
- Small commercial premises: shops, clinics and offices
- UPS duty for base stations and communication sites
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.

FAQ
Powerwall Lithium Batteries Questions
How much of the rated capacity can I actually use?
These are LiFePO4 packs specified for deep discharge, and the product pages give 95-100% DOD on the residential range. Practically, an installer sets the inverter to leave a small reserve so the pack never sits at zero, which is also what keeps the cycle count honest.
Can I start with 10 kWh and add more later?
Yes, that is the design intent. All powerwall models are 51.2V and parallel with more units of the same type. Tell the installer at the first fit to leave breaker and cable capacity for the second module and the upgrade takes an afternoon.
Which inverters do these work with?
The packs communicate over the common battery protocols used by mainstream hybrid inverters. Send us the inverter brand and model with your enquiry and we will confirm the protocol before you order rather than after.
What is the difference between wall-mount and the 30 kWh floor unit?
Mounting and scale. The 5, 10 and 15 kWh packs hang on a wall with an IP54 rating. The 30 kWh 600Ah unit is a floor-standing cabinet on wheels, for installs where the wall cannot carry the weight or the capacity has outgrown a wall-hung format.
What certificates do they carry?
CE, UL, MSDS, IEC, UN38.3 and ISO are listed on these product pages. For a grid-connected residential install, ask us which certificate your local authority requires and we will confirm what we hold for that model.
What does the five-year warranty cover?
The pack and its BMS. The published service life expectation is 10+ years at 6000+ cycles. As with any storage battery, keep the installation within the temperature and charge parameters on the datasheet - that is the part that decides whether the pack reaches its cycle rating.
