Most wall‑mounted batteries belong to split‑type energy storage. Mounted firmly on load‑bearing walls, they save floor space with slim modern appearance, well‑blended with home decoration. Typical capacity ranges 5‑15kWh, perfect for apartments and compact utility rooms. Paired with external inverters and LiFePO4 cells with smart BMS, they store surplus solar power and supply backup power during grid failure to cut peak electricity bills.

Wall load‑bearing capacity must be checked during installation. Expansion is limited to a small number of parallel units. Widely adopted in residential markets, it suits households with stable power consumption without large‑scale future expansion.
