SUNWAY 5.12kWh / 10.24kWh Wall-Mounted Lithium Battery
Description :
The SUNWAY Wall-Mounted Battery powers residential and commercial spaces. You choose between two exact sizes: 5.12kWh (100Ah) and 10.24kWh (200Ah). The system uses stable LiFePO4 cells. You get over 4,000 full charge cycles.
The flat casing mounts flush against the wall. It frees up your floor space completely. The battery stores your excess solar energy during the day. You discharge this power during expensive peak hours. You cut your daily utility bills. It also acts as an emergency backup. It runs your essential loads during grid blackouts.
It connects directly to mainstream hybrid and off-grid inverters. The built-in BMS protects the cells constantly. You can select an optional Bluetooth module for mobile monitoring. The ports use fast plug-and-play connectors. Your technicians finish the installation quickly. The hardware delivers a solid 10-year design life.
Product Advantages and Features
5.12kWh or 10.24kWh Options
You choose between two exact configurations. The 10.24kWh model delivers 9,216Wh of actual usable energy. It handles heavy daily residential loads easily. You size the system perfectly for your customer.
Wall-Mounted Casing
The flat casing mounts directly to the wall. It keeps the floor completely clear. You can install it in tight garages or small utility rooms. The clean design looks great inside modern houses.
4,000 Cycles & 0.5C Rate
It uses stable Lithium Iron Phosphate cells. It operates safely at a standard 0.5C charge and discharge rate. You get over 4,000 cycles at 25°C. The chemistry prevents internal overheating entirely.
Two-Level BMS Protection
The BMS features a strict two-level overcurrent protection system. We built in a 20% electrical design redundancy. The hardware handles sudden high-load surges safely. It stops short circuits before they damage the cells.
CAN & RS485 Integration
The board includes standard RS485 and CAN ports. It talks to most hybrid and off-grid inverters on the market. You plug in the comm cable. The inverter reads the battery parameters instantly.
Optional Bluetooth Module
You can order the battery with an optional Bluetooth module. Homeowners track daily battery health on their phones. Your installers read live voltage metrics directly. It makes on-site diagnostics much faster.
10-Year Design Life
The unit uses natural air cooling. There are no moving cooling fans to break down. The rugged internal hardware requires zero maintenance. You get a solid design life of over 10 years.

FAQs
Q1: Why is the usable energy strictly 9,216Wh on the 10.24kWh model?
We lock the Depth of Discharge (DOD) at 90%. This protects the cell chemistry. It guarantees your 4,000 cycle life. We never inflate our specs. In fact, our measured cell capacity is always 5% higher than the nominal label. You get real, durable power.
Q2: Will the battery shut down if a heavy motor starts up?
No. The internal hardware features a >20% electrical design redundancy. The 200Ah unit runs a recommended 100A continuous current. It also handles a massive 200A surge for 3 seconds. It uses a two-level protection system. The BMS and the physical circuit breaker work together. It absorbs sudden start-up loads easily.
Q3: Can I operate this battery in a freezing outdoor shed?
You can store it safely down to -20°C. But it will not operate below freezing. The strict operating temperature range is 0°C to 40°C. The smart BMS automatically blocks the charging current at 0°C. This prevents permanent lithium plating damage. You must install the unit in a temperature-controlled space.
Q4: How thick is the 200Ah unit, and how much does it weigh?
The physical depth is only 173mm. It hugs your wall very tightly. It takes up almost zero walking space. However, the total weight is 104kg. It is extremely dense. You absolutely need two strong technicians to lift it. You must bolt the heavy-duty bracket directly into solid structural supports.
