Case: Rural Home Storage Project in Hebei
A household in a rural area of Hebei Province, experiencing unstable grid power, installed a Liwei stackable system with three 5kWh modules (15kWh total) paired with 5kW solar panels. The system stores solar energy by day for use at night. During grid outages, it automatically switches to off-grid mode. Over one year, it solved the power outage issue and generated additional income by feeding surplus power back to the grid, with total annual benefits of about ¥4,000 .
Q1: How scalable is the stackable battery system?
A: It supports multi-module parallel expansion. A single system can integrate up to 60 units, reaching 300kWh total capacity. Expansion only requires adding battery modules without changing inverters, keeping expansion costs low .
Q2: Is maintenance complicated?
A: Maintenance is simple. Each battery module operates independently; a single module failure doesn't affect others. Supports hot-swapping, allowing replacement without system shutdown .
Q3: What applications is it suitable for?
A: Suitable for: 1) Home solar storage systems; 2) Backup power for small shops; 3) Telecommunication base stations; 4) Off-grid power in remote areas; 5) Emergency backup power, etc. .
