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.
Residential Solar Storage
Powerwall, stackable and rack mount 51.2V storage for homes running solar self-consumption, tariff shifting or full off-grid.
Most residential enquiries arrive with the array already installed and a question about the evening. Sike supplies the battery side of that in three formats on one voltage: wall-mounted packs from 5 to 15 kWh, a 30 kWh floor unit, stackable modules that grow 5 kWh at a time, and 19-inch rack modules for houses with an equipment cabinet. All 51.2V, all 6000+ cycles, all with a five-year warranty on the energy storage range.
Sector pain points
What Goes Wrong In This Sector
Sized For The Inverter, Not The Load
A battery specified from the inverter rating rather than the evening kWh is either too small by the second summer or too expensive to sign off.
Expansion Means A Second System
Fixed-capacity storage cannot grow. The stackable and powerwall ranges parallel on the same 51.2V bus, so the second phase is a module rather than a redesign.
Protocol Mismatch At Commissioning
The battery arrives and the hybrid inverter will not talk to it. Send the inverter model with the enquiry and it gets confirmed before shipping.
Cycle Claims With No Warranty Behind Them
6000+ cycles is the published rating on the residential range, backed by a five-year warranty and a 10+ year service life expectation.
What buyers need
What This Sector Actually Asks For
- A pack that matches the hybrid inverter already specified
- Capacity that can grow without replacing the first purchase
- Documented cycle life and a real warranty period
- CE, UN38.3 and MSDS documentation for import and installation
- A wall or floor format that suits the space the customer actually has
- A supplier who answers a commissioning question the same day

How we work with you
From Enquiry To Repeat Supply
Send The Load Profile
Daily kWh, evening peak, the inverter model and whether the system is grid-tied, hybrid or off-grid.
We Propose A Format And A Capacity
Wall mount, stackable or rack, with the module count and the expansion path spelled out.
Protocol And Documents Confirmed
Communication with your inverter, plus CE, UN38.3 and MSDS for the model you are ordering.
Sample Or First Container
Distributors usually take a sample first. Project buyers go straight to the order with the specification sheet approved.
Support After Commissioning
Settings, monitoring and warranty handled by the same people who quoted the job.

FAQ
Residential Solar Storage Questions
How big a battery does a typical home need?
It comes from the evening load, not the array. A household using 10 kWh a day with most of it after dark is a 10 kWh conversation; one with air conditioning or a heat pump moves toward 15 kWh or a stack. Send us a day of consumption data and we will size it properly.
Can I mix wall mount and stackable units?
They are all 51.2V, but mixing formats in one bank is not the clean way to build it. Pick the format at design time and expand within it. Tell us the final target capacity and we will specify the first phase so it can get there.
Do you supply the inverter as well?
No. We build battery packs. That means we are honest about protocol compatibility rather than pushing a bundle - send the inverter model and we will confirm the match.
What happens in a power cut?
That depends on your inverter's backup capability, not the battery. A hybrid inverter with a backup port will carry the loads it is wired to; the battery supplies the energy for as long as the capacity lasts.
How long will the battery last?
The published rating is 6000+ cycles with a 10+ year service life expectation and a five-year warranty on the energy storage range. Cycling once a day, that rating is the number to plan around.
Can I buy one unit as a sample?
Yes, sample orders are normal before a bulk purchase, and the source site states samples are available for testing. Ask on WhatsApp and we will quote the single unit and the freight.
