This program is for energy storage distributors and brand owners who want to sell 48V / 51.2V LiFePO4 energy storage systems under their own label, without guessing what sits behind the label. It covers residential ESS and commercial & industrial (C&I) storage: product labelling, packaging, and a written specification confirmation process that fixes the exact configuration before production is scheduled.
LJY Energy is a China-based LiFePO4 battery supplier and OEM/ODM partner offering customization, project-confirmed specifications and export supply coordination. Every option below is configured per customer project, and the confirmed specification — not a brochure — is the document both sides work to.

Program overview: two ESS tracks
The program runs on the same 48V platform family as our standard 48V LiFePO4 battery series. What changes under your label is the branding, the packaging and the documentation set — the configuration itself is confirmed model by model.
| Track | Typical buyer | Scope | Status |
|---|---|---|---|
| Residential ESS private label | Regional solar/storage distributors and home-energy brands | 51.2V wall-mounted and rack-mounted home storage systems, labelled and packed under your brand | [LJY confirmed] as program scope; models per project |
| C&I ESS private label | Commercial storage integrators and project brands | 51.2V rack systems and cabinet configurations for commercial & industrial projects | [LJY confirmed] as program scope; configuration per project |
| Specification confirmation sheet | Every program customer | A written sheet that fixes model, capacity, BMS and communication settings, label artwork, packaging and document set before an order is placed | [LJY confirmed] process step on every program |
How to read the status tags on this page: [LJY confirmed] = part of how this program runs. [Industry reference] = background information from public industry sources, not an LJY offer. [To confirm] = decided in writing for your project before ordering. Nothing tagged [To confirm] should be treated as a default.
What can carry your brand
- Product labelling: your brand name, model designation and rating label on the unit. Label content must be accurate for the actual configuration — ratings, warnings and traceability marks are not decoration, and artwork is approved by you in writing before printing.
- Packaging: your carton artwork and pallet labelling, inside export packaging specified for lithium batteries (dangerous-goods packing and marks are part of the confirmed specification, not an afterthought).
- Documentation set: user manual and warranty card under your brand, drafted from the confirmed specification. If your market requires documents in your language, say so at RFQ stage — translation is a project item, not a last-minute extra.
- Model naming: your own model numbers can be mapped to the confirmed base configuration, so your catalogue, the specification sheet and the shipped units all refer to the same thing.
The specification confirmation process
- RFQ: you send the fields listed below — market, track (residential or C&I), capacity band, estimated volumes and the documents your market requires.
- Base configuration: we propose a base model from the 48V series and state plainly what is standard, what is optional and what is not offered.
- Specification confirmation sheet: the agreed configuration is written down — electrical specification, BMS and inverter-communication settings, enclosure, label and packaging artwork, document set and inspection points. Both sides sign off on this sheet.
- Sample: a sample unit built to the confirmed sheet. The approved sample becomes the reference for the production run.
- Production and inspection: production is carried out against the sheet; inspection scope (for example pre-shipment inspection and the records supplied with the shipment) is agreed in the quotation, in writing.
This is the same discipline described on our OEM & private label hub page — this page is where that process is applied specifically to energy storage products.
Base configurations and what is confirmed per project
| Item | Program position | Status |
|---|---|---|
| Nominal voltage platform | 48V / 51.2V LiFePO4 (16S class residential and rack systems) | [LJY confirmed] program scope |
| Capacity and model list | Selected from the current 48V series range for your market and track | [To confirm] per project |
| Inverter communication | Protocol and compatibility are matched to your exact inverter model and firmware, and recorded on the specification sheet — “compatible” is only claimed for combinations confirmed this way | [To confirm] per project |
| Parallel expansion | Unit count and wiring arrangement depend on the selected model | [To confirm] per model |
| Certification and market documents | Which certificates exist, which configuration they cover and which party obtains any additional document is stated in the quotation. A certificate belongs to a specific configuration, not to a brand | [To confirm] per model and order |
| MOQ, pricing and lead time | Quoted per project stage (sample, pilot run, production run). No list prices are published for private-label programs | [To confirm] per quotation |
Two private-label lines, one coordination desk
This page covers energy storage only. If your brand sells 12V batteries for RV, marine or caravan applications, that is a separate program with different enclosures, BMS settings and fitment questions — see the 12.8V LiFePO4 private-label program for RV & marine brands. Keeping the two lines separate is deliberate: an ESS buyer asking about inverter protocols and a caravan buyer asking about DIN fitment need different specification sheets, and mixing them produces quotes nobody can compare. Tell us which line you are buying for, and the RFQ goes to the right sheet from day one.
For mixed programs (ESS plus custom packs), the custom battery solutions page and the OEM/ODM RFQ checklist are the starting points.
What to include in your inquiry
- Your market and sales channel (distribution, installation network, project supply)
- Track: residential ESS, C&I ESS, or both
- Capacity band and the inverter brands/models the systems must work with
- Estimated first-order and annual volumes (a range is fine — it sets the program stage, not a commitment)
- Branding scope: label only, or label + packaging + manuals
- Documents your market requires (certificates, test reports, declarations) and who your importer of record is
Send these via the contact form or WhatsApp +86 159 8945 0735. If you are still comparing suppliers, the OEM/ODM RFQ checklist will help you ask every supplier the same questions. Distributors comparing routes to market can also start from our distributor page and the energy storage battery range.
Frequently asked questions
What is the minimum order quantity for a private-label ESS program?
MOQ is confirmed per project and per stage — sample, pilot run and production run are quoted separately. It depends on the base model, the branding scope and the packaging specification, so any number published here would be a guess. Send the RFQ fields above and the quotation states the MOQ in writing.
Who manufactures the batteries?
LJY Energy is a Shenzhen-based LiFePO4 battery supplier and OEM/ODM coordinator, not a factory. Production is carried out by partner manufacturers; the quotation names the producing manufacturer and the party that issues each document, so you always know whose name stands behind which paper.
Which certificates come with private-label ESS products?
Certificate scope is confirmed per model and per order, and recorded on the specification confirmation sheet. A certificate covers a specific configuration — if your market (for example Australia’s CEC listing rules or EU battery regulation duties) requires a document for your exact configuration, raise it at RFQ stage so it is priced and assigned before production, not after.
Can the system work with our existing inverter line?
Compatibility is confirmed per project against the exact inverter model and firmware, and the agreed protocol settings are written onto the specification sheet. We do not claim blanket compatibility with an inverter brand — the combination you will actually install is the combination that gets confirmed.
How long does a program take from RFQ to first shipment?
Lead time is quoted per project once the specification sheet is agreed; artwork approval and sample approval sit on that timeline, so the fastest programs are the ones where the label and packaging files are ready early. The quotation separates sample lead time from production lead time.
Values and options marked [To confirm] are not LJY-verified defaults and are only binding once recorded on your project’s specification confirmation sheet and quotation. Content as of November 2026.
