Product range

Every line on the bill of materials.

A purchase order for a PV installation is never one item. Mounting, hardware, earthing, modules, inverters and batteries are bought for the same site and needed on the same day — and every extra supplier is another set of drawings, another packing list and another delay at the port. We quote the list line by line and load it into one container.

Mounting systems

Five ways to hold a module down, chosen by roof type, wind load and whether the client will accept ballast. The water ballast system is what we are known for, but it is not the answer on a pitched metal roof or a ground-mount site — so we supply the alternatives as well.

Completed water ballast array on an industrial flat roof

Water ballast system

HDPE · 6.3 → 120 kg per unit

Verified at 0.55 kN/m² wind uplift by a CMA/CNAS accredited laboratory
Zero penetrations — no anchor, no waterproofing repair
197 sets per 20GP container

Flat roofPatented

Hot-dip galvanised folded components stacked for container loading

Hot-dip galvanised racking

HDG steel · ground & roof

The conventional alternative when ballast is not accepted
Pitched or flat, anchored or weighted, fixed or adjustable tilt
Quoted against your wind and snow loads, to your section and coating spec

Ground mountPitched roofAnchored

Zn-Al-Mg rails

Zinc-aluminium-magnesium

Held at full 30 × 4.0 mm section — thickness is not thinned to hit a price
Better cut-edge corrosion resistance than plain galvanised in coastal air
Stocked, so short runs ship without a production slot

In stockCoastal

Helical ground screws

Galvanised · no concrete

Ground-mount, carport, fence and walkway foundations
Installed by machine or handheld driver — no excavation, no curing time
1,600 units shipped on a single order

Mill finish · cut to length

Rails and purlins for short-lead projects where steel fabrication is the bottleneck
Cut and drilled to your drawing before shipment

Short lead timeCustom cut

Roof hardware & drainage

The parts that stop a container, not the parts that win the tender. Small, cheap, and the single most common cause of a stalled installation when one box is missing. We keep the fast-moving items on the shelf.

Earthing & balance of system

Earthing is where inspection reports get written. Every item below is the version we actually ship, not a catalogue illustration — the jumpers are pressed onto copper lugs, the earth leads are cut to your length, and the MC4 range carries a 1000 V test report.

Grounding jumpers

Yellow-green · 10 cm

Yellow-green insulated jumper, copper lug crimped at both ends
Bonds module frames across the array — the standard 10 cm link
Sold in bulk bags, counted and packed for site distribution

BulkCopper lug

Extended earth leads

Made to drawing

Cut to your length, not a stock size
Full conductor cross-section — section is not reduced to save copper
Send a drawing or a sample; we return the same part

CustomFull section

Copper lugs & terminals

Tinned copper

Ring and fork terminals sized to the earthing conductor
Supplied loose or pre-crimped onto leads

MC4 fire covers

1000 V / 1500 V

Insulating cover that closes over an unmated MC4 pair
Two voltage classes — specify 1000 V or 1500 V, they are not interchangeable
Batch pricing applies from 1,000 sets upward — for smaller quantities ask for a retail quote

Y and T branch connectors for parallel strings
DC solar cable cut to the lengths on your cable schedule

Inverter & protection

Outdoor inverters fail from sun and rain long before they fail electrically. These are cut-to-model enclosures rather than universal boxes — send the inverter datasheet and we will match the mounting points and airflow.

Aluminium inverter covers

Cut to model

Aluminium enclosure sized to your inverter, not a one-size shell
Shades the unit and sheds rain without blocking ventilation
Mounting points matched to the manufacturer's bracket

Modules, inverters & storage

Everything above the mounting is a brand decision, and it belongs to you. We do not build modules, inverters or batteries — we supply them from the factories already on your approved vendor list, quote them on the same sheet as the hardware, and load them into the same container. One arrival date instead of four is the whole argument.

PV modules

Monocrystalline · N-type TOPCon

Tier-1 module brands quoted against your approved vendor list
Bifacial and monofacial, 54- and 72-cell formats for rooftop and ground
Frame thickness confirmed before the order leaves, so the clamp on the mounting matches the module that arrives

Tier-1BifacialTOPCon

Grid-tied inverters

3–110 kW · single & three phase

String inverters from established brands, with the datasheet and certification pack attached to the quotation
String sizing checked against the module you are actually buying, not a generic table
If the unit sits outdoors, the aluminium cover is cut to that model

On-gridString

Hybrid & off-grid inverters

With or without battery

Hybrid units for sites that will add storage in a second phase
Off-grid units sized against the load profile, not against a headline wattage
AC and DC protection quoted on the same line as the inverter

HybridOff-grid

Battery storage

LFP · 5–100 kWh

Wall-mounted, rack-mounted and cabinet systems
Sized against one night of load and the depth of discharge the client will accept
Ships under the same customs declaration as the mounting and the modules

LFPRackCabinet

A matched kit, not a shopping list

One BOM in, one price out

Send the bill of materials for the whole site; it comes back quoted line by line
Module frame, clamp, rail section and inverter model are checked against each other, not quoted in isolation
One packing list, one commercial invoice, one declaration for the container

MatchedOne container

These items are not manufactured by DINGXIU. The brand and model are named on the quotation, and the datasheet and certification pack for that exact model are attached to it.

Ordering

How a mixed order is quoted and shipped.

Most of what is on this page has no public price list, because most of it is quoted against a specification. Here is what we need from you, and what you get back.

What to sendTo get a usable price: Specification (section, thickness, voltage class, material), quantity, destination port, and whether you need a VAT invoice. Miss one and the number has to be issued twice.
Stock statusBefore you promise a date: Every line is quoted as in stock, in production or being packed. We do not quote a shipment date we cannot confirm — if the stock answer is unclear, we say so and come back.
Mixed containersThe point of using one supplier: Ballast units, rails, clamps, jumpers and covers load into the same container. One packing list, one invoice, one customs declaration, one arrival date instead of four.
Custom partsDrawing in, part out: Earth leads to length, corner brackets to an export drawing, inverter covers to a model number. Send the drawing or the datasheet and we confirm feasibility before quoting.
DocumentsFor your tender file: 1000 V MC4 test report, CMA/CNAS test report for the ballast system, patent certificate 202630294473.0, datasheets, packing lists and commercial invoice. Datasheets and drawings go out as PDF; full test reports are released by email against a project.

Send the bill of materials. We quote line by line.

Mounting, hardware, earthing, modules, inverters, storage — one list, one reply, with stock status against each line.
