SMSBESS manufactures LiFePO4 lithium battery packs in 5kWh, 10kWh, 15kWh, 16kWh, 20kWh and 30kWh capacities for home energy storage. All variants share the same 51.2V LiFePO4 battery architecture and 8000-cycle A-grade cells, so you can mix capacities in parallel up to 16 units (480 kWh max). The 15kWh / 16kWh / 20kWh sizes are our best-selling residential energy storage battery configurations in EU and AU markets.
"48V LiFePO4 battery" is the industry shorthand. The actual nominal voltage of a 16-cell LiFePO4 battery string is 51.2V (16 × 3.2V). Inverters labelled "48V" all accept the 51.2V LiFePO4 battery range (44V–58.4V), so a 51.2V LiFePO4 battery is fully compatible with any 48V solar hybrid inverter on the market — Deye, Growatt, Victron, SMA, Sungrow, EG4 and others.
A 15kWh lithium battery covers roughly 1–1.5 days of typical residential consumption (10–15 kWh/day) for a 3-bedroom home running essential loads (lights, fridge, router, TV, AC compressor cycling). For full-home off-grid backup or larger AC loads, scale up to a 20kWh or 30kWh lithium battery. Our standing battery line ships pre-wired and parallels in 10 minutes — no electrician for the battery side itself.
SMSBESS is a wholly-owned subsidiary of Zhengzhou Sanhui Electric Co., Ltd. (SZSE: 002857), a publicly listed industrial electric group founded in 1996. We operate our own LFP cell line, BMS line, PCS factory and final assembly — a true vertically-integrated BESS manufacturer, ESS manufacturer and lithium battery manufacturer. 30 GW+ inverters and energy storage battery systems shipped to 150+ countries since founding.
Yes — we hold inventory of 10kWh, 15kWh and 16kWh lithium battery SKUs in our EU warehouse (Germany & Poland) for 7–10 day delivery to most EU countries. Larger 20kWh / 30kWh variants and bulk orders ship 30–45 days from our Shenzhen factory. Talk to our sales team for live stock and freight quotes.
