Hebei Mutian Solar Energy Technology Development Co., Ltd. is one of the most reliable manufacturers and suppliers of 15kwh lithium battery in China, also supports customized service. Welcome to buy advanced 15kwh lithium battery in stock from our factory.
Home Energy Storage System
Customers look for energy independence, and your company needs a solution to provide it without a hitch. This self-reliant energy storage device has been made to be the star of your renewable energy inventory.
Unlike conventional battery banks requiring several suppliers, intricate wiring systems, and several inverters, this 15kWh Lithium battery combines all these elements into one compact mobile unit. It has been designed for off-grid uses, commercial power backup, and solar energy use. If your customer base is in wholesale, this product represents a complete solution with assured availability and profitability as well as a wide certification spectrum.
Why This Product Belongs in Your Catalog
Wholesale buyers do not just purchase products-they purchase solutions their customers will trust. This 15kWh Lithium battery solves the three biggest pain points in energy storage:
Installation complexity – All-in-one design eliminates separate inverter and battery sourcing. Your installers save time, and your support team handles fewer compatibility calls.
Safety concerns – LiFePO4 chemistry and intelligent BMS provide peace of mind that end users demand.
Scalability – Parallel capability means one SKU can serve small homes, large villas, and small commercial sites. You reduce inventory complexity while increasing average order value.
Product Advantages That Sell for You
1. True All-in-One Architecture
Battery, inverter, BMS, and monitoring are factory-integrated and tested as one system. No third-party compatibility issues. No mismatched components. Your customers receive a single, validated solution-and you receive fewer technical support tickets.
2. Pure Sine Wave Output
Clean, stable power protects sensitive electronics: medical devices, computers, smart home systems, and industrial controls. This is a key selling point for customers who cannot afford power quality problems.
3. LiFePO4 Safety and Longevity
Lithium Iron Phosphate (LiFePO4) battery technology is the safest alternative lithium chemistry. This is due to it being virtually unaffected by thermal runaway, performing well under high temperatures, and offering thousands of charging cycles. Your clients enjoy long periods of reliability, while you have fewer warranty returns.
4. Modular and Scalable
Different capacity variants can be built up. The same product range is applicable to different segments of the customer market with the exception of the capacity range from powering one room to whole houses and small businesses, which allows you to minimize your stock and increase your market.
5. Smart Connectivity
Thanks to built-in Wi-Fi and Bluetooth technology, a client can remotely control the unit and monitor its use through a mobile application. This makes it possible to do remote diagnostics.
6. Mobile and Aesthetic Design
This compact cabinet features a modern design and is equipped with casters at the base; it is suitable for garages or equipment rooms, yet remains manageable for residential users and installers alike.

Manufacturing Consistency: How We Protect Your Brand
Your reputation depends on every unit performing the same way. We build consistency into every step:
Cell sorting: All cells are subjected to OCV (open-circuit voltage) and IR (internal resistance) evaluations prior to the assembly process, with all non-compliant cells being discarded.
Laser welding: Laser welding is the method of interconnecting modules as opposed to using manual methods of spot welding. This leads to better reliability of electrical connection resistance and strength.
BMS validation: Each BMS system undergoes testing to confirm proper communication, protection levels, as well as balancing functions before being integrated with the battery pack.
Aging test: After assembling the batteries, their performance is assessed during charging and discharging cycles performed in the aging room that is equipped with controlled temperature system.
End-of-line (EOL) test: Before putting the unit into the packaging, it undergoes rigorous testing to check the performance and safety of the device. Data obtained in tests is transferred into the MES system.
Serial number traceability: Each device receives a unique number which will allow identifying individual cell batch, BMS batch, assembly date, and test results of the device. In case of any quality issues arise, it will be possible to trace all the way back.
Why this matters to you: When your customer reports a problem, you will not be left guessing. We can identify the batch, the test data, and the likely cause within hours, not days.
