When the grid drops, the useful question is simple: which loads still need to run, and for how long? Capacity printed on a label is not runtime until the appliances have been counted. The S Series gives households, small retailers, mobile vendors, and field teams three portable lithium iron phosphate (LiFePO4) backup options for unreliable-grid and outdoor-use markets.
If you operate the equipment, start with the AC load, the required duration, the charging opportunity you actually have, and how many sockets are in use at once. Those four answers narrow the model; the specification then confirms it.
If you are building a distribution or private-label range, the three models form clear 300W, 500W, and 1000W positions on one chemistry, which keeps the range simple to explain and simple to position. Ask during quote review whether original equipment manufacturer (OEM) or private-label packaging belongs in the commercial scope.
The three models
8.8 kg · AC charge 3–4 h. Volume / entry.
S1000 specification9.0 kg · AC charge 2–3 h. Same size, more power.
S1000 Pro specification16.8 kg · AC charge 2–3 h. Dual socket, sub-15 ms switchover, 550W solar.
S2000 Pro specificationAll three: LiFePO4, 6,000 cycles to 80% state of charge, pure sine 230V 50/60 Hz, ingress protection IP20, −10°C to 40°C, UN38.3 and CE. Specifications come from the Energy Storage business-unit sheet dated 20 August 2026; we reconfirm them before a binding quote.
Portable backup is not site storage
The S Series covers portable, model-level backup. For load-level engineering around a complete site, duration, and duty cycle, start with site-level energy storage projects.
Connects to operations: field kits, pop-up retail, weak-grid warehouses. See Mobility and site power, which names the hardware, software, and services included, with responsibilities agreed per project.
