Stackable residential systems from 5.12 kWh to 36 kWh, engineered around Grade A LiFePO4 cells and a 5,500 W bidirectional inverter. Supplied direct from our own assembly line to distributors, installers and brand owners — with your logo, your packaging and your datasheet.
Configured price, spec sheet and freight options — in one reply.
We build to the three failure points that decide whether a residential storage line sells — cost per kWh, grid fit, and paperwork at the border.
Cells, BMS, inverter and enclosure are assembled in one facility. You buy the finished stack, not a rebadged import with two margins stacked on top.
230 V / 50 Hz as standard for Europe. Split-phase and other voltage variants are quoted against the actual datasheet for your destination — never assumed.
UN38.3, RoHS and MSDS packs ship with the quotation, so your customs broker and your installer both get what they ask for on the first email.
One control unit on top of four 9,000 Wh battery modules. A five-layer tower that fits a utility room, a basement or a garage wall — and carries a European household through the night instead of just the evening.

Power and capacity ratings are the published figures for each model. Models are configurable — tell us the target retail price and we will propose the matching configuration.
Rigid or flexible, 50 W to 550 W, on the same 22% monocrystalline platform — so the array and the stack are quoted as one system, not two shipments from two suppliers.
Framed monocrystalline modules built on HJT, N-Type or TOPCon cells at 22% panel efficiency — the default for a pitched residential roof or a ground-mount frame.
A 4 mm monocrystalline laminate with 144 cells at 125 × 125 mm, for surfaces where a framed module will not sit flat — curved roofing, balcony rails, vehicle roofs.
The P-6 control unit carries a 60–130 V MPPT input rated 5,000 W with a suggested 5,000 W array. Module count and string layout are set against the inverter you actually order.
Brackets, connectors, cable, enclosures and the crimping kit — quoted on the same order as the modules and the stack, so an installer is not chasing three suppliers for a forty-line bill of materials.
Flat roof, ballasted, sloped metal roof, industrial rooftop and ground-mount systems in anodised aluminium alloy, steel and stainless steel.
IP67 MC4 pairs rated 1000 V and 1500 V, paired with PV1-F and H1Z2Z2-K single-core cable in 4, 6 and 10 mm².
DC combiner boxes and roof cable-entry housings in ABS or PVC with an anti-UV additive, PG11 glands and a single sealed roof penetration.
A solar cable crimper, two connector wrenches, a male and female connector pair and pins in a storage bag — the kit used on every roof.
Nothing proprietary in the chain. Your installers keep their existing PV racking, their existing AC wiring and their existing commissioning routine.
String array sized to the 5,000 W MPPT input, 60–130 V window.
Tracks the array and routes daytime surplus into the battery stack.
4 × 9 kWh modules at 51.2 V, managed by a shared BMS.
5,500 W in and out — AC loads, grid charging, backup output.
Essentials circuit backed up; heavy loads stay on grid by choice.
Volume, configuration and branding differ — the production line does not. Tell us which of these you are and the quotation arrives already structured for it.
Stock a range that covers the whole residential market without carrying five brands.
One platform to learn, one commissioning routine, one spare-parts shelf.
Multi-unit clusters for villas, guesthouses and off-grid properties.
Your logo, your enclosure silk-screen, your datasheet and your packaging.
No hidden minimums, no “contact us for pricing” loop. These are the terms we work to every day.
Certification status is model- and market-specific. We state exactly what is held, and what is pending, before you place an order — so nothing is promised that the paperwork cannot support.
Something not covered here? Send it on WhatsApp — technical questions usually get an answer the same working day.
Ask on WhatsAppOne unit. We would rather you install a single system, test it against your own load profile and then scale, than talk you into a container you cannot sell.
230 V / 50 Hz is the standard configuration for European markets. Split-phase 120/240 V and other variants are quoted on request and confirmed against the actual datasheet for that model before you order — we do not assume a voltage.
3–7 days from deposit, depending on order volume and configuration. Sample orders are prioritised so you can test quickly.
10–15 kWh covers a typical family home with a heat pump. The 36 kWh P-6 stack is for whole-home backup across the night, larger properties, guesthouses and rural sites. Tell us the daily consumption and we will size it.
Yes. OEM / ODM covers enclosure silk-screen, nameplate, manual, datasheet and packaging, typically from 50 units. Below that we can still supply neutral cartons.
UN38.3, RoHS and MSDS documentation is supplied with the quotation, along with cell and pack test reports. CE, UL and grid-code approvals are model- and market-specific — we confirm exactly what is held for your destination rather than listing claims the paperwork cannot support.
A deposit confirms the order; the balance is settled per the agreed terms. Freight is quoted per destination, and we will load a mixed container across models if that is what your market needs.
One email back with the quotation, the datasheet for the exact model, and the freight options to your port. No catalogue PDFs, no follow-up sequence.
