Wall-mounted household energy storage battery

In the era of distributed energy and growing household green electricity consumption, the wall-mounted household energy storage battery is becoming an essential component of modern smart homes. This product is specifically designed for residential applications, adopting a compact wall-mounted form factor that integrates high-performance lithium iron phosphate (LiFePO₄) battery cells with an intelligent battery management system (BMS).

This storage battery works efficiently with residential PV systems, the grid, and household loads. During the day, solar power supplies household loads first, with excess energy stored in the battery. At night or during a grid outage, the battery automatically powers critical loads such as refrigerators, lighting, networking equipment, and security systems. Its core objectives are: increasing self-consumption of green electricity, reducing electricity bills, and providing emergency backup power.

With a minimalist flat design and rounded corners, available in white or grey, the unit blends seamlessly into modern home environments. The entire system has an IP65 rating, offering excellent dust and water resistance for safe installation on indoor walls, in garages, or on enclosed balconies.

Product Features
Safe and Long-Life Battery Chemistry
Automotive-grade LiFePO₄ cells offer superior thermal stability compared to NMC chemistries – no fire, no explosion. Cycle life ≥6000 cycles, calendar life >10 years, significantly reducing total cost of ownership.

Space-Saving Wall Mounting
With a thickness of only approx. 10–15 cm, the unit can be directly mounted on load-bearing walls, occupying zero floor space. Hidden bottom cable routing ensures a clean, minimal cable exposure after installation.

Intelligent Energy Management
A high-precision BMS monitors voltage, current, and temperature in real time, and supports customizable charge/discharge strategies. Via a mobile APP, users can view household energy flow, battery status, and historical data, and enable “low-price charge, high-price discharge” arbitrage under time-of-use tariffs.

Seamless On/Off-Grid Switching
When paired with a hybrid inverter, the system automatically switches to off-grid backup mode within 20 ms after a grid failure, ensuring uninterrupted operation of refrigerators, aquariums, networking equipment, and other sensitive devices.

Modular Expansion
Single-unit capacity typically ranges from 5 kWh to 15 kWh, supporting up to 4 units in parallel for a total capacity of up to 60 kWh. Users can expand gradually based on household demand, avoiding high upfront costs.

Quiet and Eco-Friendly
Fanless natural convection cooling keeps operating noise below 25 dB, completely undisturbed during sleep. All materials comply with RoHS, and the battery is recyclable at the end of its life.

As a national high-tech enterprise with years of deep expertise in the energy storage sector, we possess full-chain in-house R&D and manufacturing capabilities – from cell modules and BMS to complete system integration. The following advantages ensure we are a trustworthy partner for you:

Smart Manufacturing & Quality Control
Our factory employs fully automated cell sorting, laser welding, and aging test lines. Each battery is subjected to charge/discharge, insulation/withstand voltage, communication handshake, and 48-hour high-temperature aging tests before delivery. The outbound defect rate is below 0.2%, far better than industry average.

Flexible Cooperation & Service
We offer OEM/ODM services, including custom appearance graphics, BMS parameters, and communication protocols (CAN/RS485/dry contact). A 24/7 technical hotline and global spare parts warehouses are available. Core components come with an extended warranty of 5–10 years. Installation documentation and video tutorials are fully accessible.

Proven Customer Reputation
Over 30,000 wall-mounted energy storage systems have been deployed in high-standard markets such as Germany, Australia, and Japan – with zero safety incidents. Customer feedback consistently highlights easy installation, user-friendly APP, and seamless off-grid switching.
