Battery energy-storage systems: commercial cabinets and utility containers
ZeroLine supplies finished lithium iron phosphate (LFP) storage from audited makers in Hubei and across China: 100–261 kWh cabinets for factories, sites and microgrids, 5 MWh-class containers for utility projects, PCS and energy-management systems, and backup batteries. We size the system to your load profile, witness the factory test, ship it as dangerous goods and commission it on site.

FAQ
Questions buyers ask
How much does a battery storage system cost in 2026?
For orientation: all-in-one commercial cabinets typically quote at USD 0.12–0.20 per Wh FOB China, and utility DC blocks lower per Wh. In China, the average winning bid for LFP storage systems in the first half of 2026 was about RMB 0.555 per Wh. Price depends on cell, cooling, PCS, certificates and quantity; we quote the exact system for your site.
Which certificates do the systems have?
Commonly IEC 62619 for cells and battery systems, UN38.3 for transport and IEC 62477-1 for power converters; UL 9540 and UL 9540A where the market requires them; grid-code certificates for the inverter where your utility asks. Each quotation lists the certificates of the exact model.
What warranty comes with the system?
Typically 5 years on the system and 6,000 or more cycles to 70% capacity on the cells, with extended warranties available. Terms are written into the contract.
Can we assemble storage cabinets in our own country?
Yes. Many customers start with finished cabinets, move to assembling racks and cabinets from kits, and then add a Stratavolt module and PACK line. See local manufacturing.
