Different specs for different markets

A 2.4kWh unit that sells in Germany is not the same SKU that sells in Nigeria or the Gulf. Below is how the range splits by job, so you can pick a starting model instead of buying a mixed container.

Why buyers stay

What you get beyond a price list

Factory-direct, with the paperwork to prove it

We buy from Guangdong Boltpower Energy and ship as the exporter of record. You get the factory's data sheets, its ISO certificate, and one contact in Wuhan.

A certification pack per order

CE, RoHS, UN38.3 and FCC documents are collected against the exact SKU and plug type you order — not a generic catalogue PDF.

Plug and voltage set before production

Schuko, UK, IEC C14, 120V or 230V panels are configured on the line, so the unit matches the market it ships to.

Private label without a tooling bill

Logo, housing colour, panel silkscreen, manual and carton change on the existing platform. MOQ applies; a new mould usually does not.

Spare parts and a repair path

Fuses, fans, inverter boards and panels ship with the container, so your service partner is not waiting on one parcel.

Logistics that respect UN38.3

Battery-class packing, MSDS and shipping documents prepared before the container is booked. FOB, CIF or DDP quoted.

Private label

Eight things you can change without new tooling

If a line is not on this list, ask — most changes are possible; the only question is whether they need a new mould.

LogoPanel silkscreen, top label and carton, one or two colours.
Housing colourStandard black or grey; a brand colour on volume orders.
Plug and panelSchuko, UK, IEC C14, 120V or 230V, set per market.
LanguageManual, box and panel text in EN, DE, FR, ES, IT, PL or your copy.
PackagingBrown box, colour box, or a mailer sized for e-commerce.
AccessoriesAC cable, car cable, MC4 adapter, carry bag, dust cover.
Firmware limitsOutput ceiling, charge current and display behaviour for your service network.
Certification scopeAdditional testing for a specific market, quoted per project.
From inquiry to container

Six steps, no mystery in the middle

01

Model and market

You give us the market, the load and the retail price band. We come back with one or two SKUs, not a catalogue.

02

Quotation

FOB, CIF or DDP, with plug type, packaging and certification scope written into the quote.

03

Sample

One unit by express, with the data sheet and the certificate pack for that SKU.

04

Validation

You test the unit, check the panel against your market, and approve packaging artwork.

05

Production

Cells matched, packs assembled, 100% pre-shipment inspection with a photo record.

06

Shipping

UN38.3 packing, MSDS, booking, and documents sent before the vessel sails.

Quality control

Six checks before a unit leaves the line

01

Incoming cells

Capacity, internal resistance and appearance checked by batch before a pack is built.

02

Pack assembly

Spot welding, insulation and BMS wiring inspected against the drawing.

03

Functional test

AC output, USB-PD negotiation, solar input, UPS transfer and display accuracy.

04

Burn-in

Units run under load so early failures happen in the factory, not at your customer's house.

05

Safety and packing

Overload, over-temperature and short-circuit protection verified; UN38.3 packing checked.

06

Pre-shipment inspection

Carton, label, accessories and quantity against the order, photographed before loading.

Compliance

Documents we can put in your hands

ISO 9001:2015Factory quality system, cert. 064-26-Q-1805-R4-01, valid to 14 Oct 2029.
UN38.3 + MSDSBattery transport documents for air and sea, issued per pack model.
CE / RoHSEU declarations and test reports; coverage depends on the SKU and plug type.
FCC / PSEAvailable for US and Japan configurations where the SKU supports it.
Important note. Certification coverage varies by model, by plug standard and by destination market. A CE mark on a 230V Schuko SKU does not automatically cover a 120V version of the same product. Tell us the market and we will confirm which documents apply to the exact unit you are buying — before you print a compliance claim on the box.
How we work together

Five steps from first message to repeat order

01

Requirement

Market, load, quantity, price band and packaging expectations.

02

Quote

Model, Incoterm, MOQ and lead time in one document.

03

Sample

One unit to test, with the documents for that SKU.

04

Order

50% deposit, balance before shipment; inspection photos before loading.

05

Repeat

Spare parts and a fixed spec sheet, so the second container matches the first.

FAQ

Questions importers ask first

Are you a factory or a trading company?
A trading company — Wuhan Longyan Innovation Trading Co., Ltd. (武汉市龙言创新贸易有限公司), registered in Wuhan, Hubei. The factory behind the products is Guangdong Boltpower Energy Co., Ltd. in Tangxia, Dongguan (ISO 9001:2015). We buy from the factory and export as the seller of record. We say it plainly because the same answer appears in the certificate and in the invoice.
What is the minimum order?
One unit for a sample. For production the MOQ is 50 units on industrial models and 100 units on portable models; the best unit price band starts at 300 units. Mixed containers are possible — tell us the split and we quote it as one shipment.
What are the payment terms?
50% deposit on order confirmation, balance before shipment. For a first order we can quote 30/70 against a sample. Payment by T/T; deposit and balance sit on the same proforma invoice.
Which certifications come with the unit?
CE and RoHS test reports, UN38.3 and MSDS for transport, and the ISO 9001 certificate for the factory. FCC and PSE are available for configurations that support them. Coverage is per SKU and per plug type — we confirm the exact list in the quote so you are not relying on a catalogue claim.
Can I put my own brand on it?
Yes. Logo, housing colour, panel silkscreen, manual language, carton design and accessory set all change on the existing platform. Send the artwork and we return a proof before production; a new mould is only needed if you change the enclosure itself.
How long is production and shipping?
Samples ship in 3–7 days by express. Production is typically 25–35 days after artwork approval, depending on model and quantity. Sea freight to Europe is about 30–40 days port to port; we quote FOB, CIF or DDP so landed cost is visible before you commit.
What about warranty and spare parts?
The factory warranty is 12 months against manufacturing defects, with free replacement of defective units. Fuses, fans, inverter boards and panels can ship with the container so your service partner is not waiting on a single parcel. Extended terms are negotiable on volume orders.
Can you ship batteries by air?
Only with UN38.3 test reports and the correct packing instruction, and only on carriers that accept class-9 goods. For most orders sea freight is cheaper and simpler; air is used for samples and urgent replenishment. MSDS and the shipper's declaration are prepared before booking.
