Powerwall Lithium Batteries
10 kWh 51.2V 200Ah Wall Mounted LiFePO4 Battery
The volume seller in residential storage: 51.2V 200Ah, 10 kWh, wall mounted at IP54.
Product Overview
The volume seller in residential storage: 51.2V 200Ah, 10 kWh, wall mounted at IP54. It covers a typical family home's evening consumption with enough margin that the pack is not emptied nightly, and it uses the same LiFePO4 cells, smart BMS and 51.2V bus as every other pack in the range, so an installer who has fitted one Sike powerwall has fitted them all. Rated 6000+ cycles with a 10+ year service life expectation and a five-year warranty.
Key benefits
Why Buyers Choose This Pack
The Size Most Homes Actually Need
10 kWh covers the evening load of a typical household with margin, which is why it is the size most residential quotations land on.
Compact Wall Format
Hangs in a garage or utility room and keeps the floor clear, with an IP54 rating that tolerates dust and splash.
Parallel Expansion On One Bus
Add a second pack for 20 kWh without changing the inverter or rewiring the system.
Five-Year Warranty On 6000+ Cycles
Cycled once a day, the published rating is a decade and a half of service, with a warranty that puts a number behind it.
Application scenarios
Where It Is Used
- Solar self-consumption for a family home
- Evening load shifting on a time-of-use tariff
- Backup for essential circuits during outages
- Small commercial premises such as a shop or clinic
- Off-grid homes with a modest overnight load
- First phase of a system designed to reach 20 kWh
Who it is for
The Buyers This Pack Suits
Residential Solar Installers
Fitting storage to an existing array where the inverter and wall position are already decided.
Distributors And Brand Owners
Carrying the highest-volume residential size under their own label.
Homeowners Cutting Grid Import
Storing the afternoon surplus and using it after dark instead of exporting it cheaply.
Problems it solves
What It Fixes
Evening Import At Peak Rates
Solar without storage exports cheaply at noon and buys back expensively at seven. 10 kWh is usually enough to close that gap.
Floor Space In A Small Plant Room
A wall-mounted pack leaves the floor for the inverter, the consumer unit and the person servicing them.
Capacity That Cannot Follow The Household
Parallel expansion on the same 51.2V bus means the second child, the EV or the heat pump does not force a new system.

Packing and documents
How It Ships And What Comes With It
Packing And Shipping
Packing follows UN38.3 requirements for lithium battery transport, and the carton and pallet arrangement is confirmed with the quotation for your quantity and destination. We do not publish a fixed carton specification here because it changes with order size and freight mode.
Documentation
UN38.3 and the MSDS travel with every lithium shipment, and the certificates listed in the specification table above are supplied for the model you order. Tell us the destination market at the quotation stage so the document set is planned rather than chased after the goods are built. Where a certificate we do not hold is required, we will say so rather than promise it.
Manufacturing
This pack is built at Shenzhen Sike Power Technology Co., Ltd. in Da Peng New District, Shenzhen, with cell grading, assembly, BMS integration, aging test and final inspection carried out in house. Only brand-new grade A LiFePO4 cells and a top-brand smart BMS go into it.

Installation guide
Getting It Right First Time
Step 1
Verify the wall and fixings against the loaded weight, and leave clearance for airflow around the case.
Step 2
Send the inverter brand and model to us so protocol compatibility is confirmed before the pack ships.
Step 3
Set the inverter to hold a small reserve so the pack is not driven to empty daily.
Step 4
Keep the mounting position out of direct afternoon sun to avoid unnecessary thermal load.
Step 5
If 20 kWh is likely later, run cable and breakers for two packs during the first install.

FAQ
10 kWh 51.2V 200Ah Wall Mounted LiFePO4 Battery Questions
Is 10 kWh enough for my house?
For most family homes covering the evening, yes. The honest test is a day of interval data - send it and we will size it rather than quoting a rule of thumb.
Can I add a second pack later?
Yes, in parallel on the same 51.2V bus. Up to fifteen units are published for the wall-mounted range - the practical limit is usually the inverter and the wall.
Wall mount or rack mount at 10 kWh?
Wall mount if the capacity is settled and there is a suitable wall. Rack mount if the property has an equipment cabinet or you want field-swappable modules.
What is the IP rating?
IP54 - dust protected and splash resistant, suitable for a garage, utility room or sheltered external wall.
Which certificates apply?
CE, UL, MSDS, IEC, UN38.3 and ISO are listed for this pack.
What is the warranty period?
Five years, against a published 6000+ cycle rating and a 10+ year service life expectation.
