Wall-Mounted Lithium Battery

Optimized Space Utilization: Ideal for spaces like garages and equipment rooms where floor space is limited. The compact design also allows for more centralized cabling and a tidier environment.

Blends into Home Environments: The exterior design is typically refined—featuring ultra-thin profiles as slim as 130mm and concealed interfaces—which integrates well with modern home decor, resembling a household appliance.

Easy to Install: Can be directly fixed to load-bearing walls without the need for complex cabinet assembly.

Quick Setup: Since they are positioned close to the inverter, the DC-side wiring is shorter, effectively reducing line losses and installation time.

Safe, Reliable, and High Performance

High Safety Standards: Widely use Lithium Iron Phosphate (LiFePO₄) cells, which are chemically stable and highly safe. The built-in intelligent Battery Management System (BMS) provides real-time monitoring and multiple protections against overcharge, over-discharge, overtemperature, short circuits, and more. Some models achieve an IP65 protection rating, offering dustproof and waterproof capabilities.

Long Cycle Life: High-quality cells commonly exceed 6,000 cycle life, with a design lifespan of 10 to 15 years. Additionally, their low self-discharge rate makes them suitable for long-term storage.

Flexible Scalability, Smart and Convenient

Modular Expansion: Support parallel connections with multiple units, allowing flexible capacity expansion as needed—for example, starting from a single 5kWh module and scaling up to 90kWh or even higher.

Smart Connectivity: Equipped with Bluetooth, Wi-Fi, and other functions, enabling convenient system monitoring via mobile apps. They are also compatible with the vast majority of mainstream inverters on the market, ensuring good adaptability.

Cost-Effective and Widely Applicable

High Cost Performance: Due to their relatively simple structure, wall-mounted models are typically 15%–25% cheaper than rack-mounted or stackable types for the same capacity.

Diverse Application Scenarios: Well-suited for residential PV energy storage, small retail stores, backup power, off-grid systems, and similar use cases.

Installation Considerations

Wall Load-Bearing Capacity: Before installation, make sure the wall is a load-bearing wall capable of supporting the battery's total weight, which often ranges from 80 to 120 kg or more.

Heat Dissipation and Planning: Wall-mounted units typically rely on natural convection cooling, so ensure the installation environment has good ventilation. Also, their single-unit capacity and future expandability are relatively limited, making them better suited for scenarios with relatively fixed electricity demands.

Charge Frequently, Not Deeply: The best habit is to "charge whenever convenient, with shallow charges and shallow discharges." Try to keep the charge level between 20% and 80%, avoiding prolonged periods of low charge or full charge.

Avoid Deep Discharge: Try not to drain the battery completely before recharging. Frequent deep discharging puts significant stress on the battery internals and accelerates aging.

Long-Term Storage: If you plan not to use the battery for an extended period (e.g., more than a week), it's best to keep the charge level at around 40% to 60% and store it in a cool, dry place. If storage exceeds 3 months, it is recommended to first fully charge the battery, then discharge it to 40%–60% before storage, to prevent damage from over-discharge.

There is one important nuance to note: For lithium iron phosphate (LiFePO₄) batteries, some manufacturers recommend performing a full slow charge (to 100%) once a week or once a month to calibrate the State of Charge (SOC) displayed by the Battery Management System (BMS), preventing sudden charge jumps. This does not conflict with the daily shallow charge/discharge recommendation.

Suitable Temperature Environment

Lithium batteries are sensitive to temperature, with an ideal operating range between 15°C and 25°C.

Avoid High Temperatures: High temperatures accelerate internal chemical reactions, leading to capacity loss and even potential safety risks. In particular, avoid direct sunlight and storing the battery in enclosed, hot spaces.

Watch Out for Low Temperatures: In low-temperature environments, battery activity decreases, resulting in a temporary reduction in usable capacity. Charging also requires milder conditions. In cold weather, avoid charging the battery below 0°C.

Visual Inspection and Connections

A simple visual inspection once a month is recommended:

Check the battery casing for cracks, bulging, leakage, or other abnormalities.

Inspect connecting cables and terminals for looseness, corrosion, or rust.

Cleaning and Ventilation

Regularly wipe dust off the battery surface with a dry cloth, especially around ventilation openings, to help the battery dissipate heat more effectively.

Ensure the battery is installed in a dry, well-ventilated location and avoid operating it in humid environments.

Safety Reminders

Use Compliant Equipment: Always use chargers and accessories that meet national standards; prioritize original manufacturer products.

Do Not Disassemble: The battery has a precise internal structure. Non-professionals should never disassemble or attempt repairs on their own.

Stop Use Immediately if Faults Occur: If you notice abnormally long charging times, significant range reduction, bulging, leakage, unusual noises, or other irregularities, stop using the battery immediately and seek professional assistance.
