Zhejiang Jiaming Tianheyuan Photovoltaic Technology
浙江佳明天和缘光伏科技有限公司
A Cixi maker of PV junction boxes, connectors and cables inside the wider Jiaming group. Its PV-JM807 box is listed at 1000 V DC with a 6A family row, so the diode and the current definition are the first things to settle with the factory.

Company scope
What the company makes
Zhejiang Jiaming Tianheyuan Photovoltaic Technology (浙江佳明天和缘光伏科技有限公司) supplies parts that go into PV modules: junction boxes, intelligent junction boxes, connectors and cables. Its company page sets the PV business apart from Ningbo Jiaming Metal Products and from the group's new-energy equipment arm. The timeline puts the metal business at 1987 and the PV company at 2005, so 2005 is the founding year that matters to a junction-box buyer.
The shared website also covers valve plants, pressure-pipeline licences and gas customers. Those belong to the metal and valve side of the group. For PV parts, the useful items are the junction-box laboratory described in the PV section and the national standards record, which lists this PV company among the drafting organisations of GB/T 37410-2019. Ask for the laboratory's current scope and for model certificates to sit alongside that record.
PV-JM807 is the catalogue box to start from. Jiaming gives 1000 V DC, contact resistance of 0.5mΩ or less and IP65 for the mated assembly. The family table shows a 6A row, and the product text says a different diode changes the maximum working current. Ask which diode the 6A row assumes and at what temperature it was measured, then judge the box against your own module. Quote on that exact part and its certificate annex; the group's overall size and its market-share statement say little about one junction box.

Settle before quoting
Pin down the PV-JM807 version that matches your module
Voltage and current sit in separate fields
The specification gives 1000 V DC. The family table puts 6A under an unusual current heading, and the feature text says the choice of diode changes maximum operating current. Ask for the diode part number and the rated-current definition with its temperature and test conditions. [2]
Enclosure, lid and cable
IP65 is stated for the mated condition, and cable comes in 2.5mm² and 4mm². Specify the full enclosure, lid, cable exit and connector so the protection rating applies to what you actually install. [2]
Documents to request
Tie the certificate to the exact PV-JM807 bill of materials
Fix the variant
Ask for a controlled outline and terminal drawing, the diode type, cable build and the matching connector pair. Freeze this version before comparing samples or reading the current rating. [2]
Match certificates to the model
The product page carries a TÜV label without a certificate number or model annex. Request current certificates showing holder, factory, variant, materials and test conditions. The GB/T 37410-2019 drafting role is useful background next to them. [2][4]
Trial on your own module
Agree the ribbon connection, box bonding, sealing and any cure step with Jiaming. Run the trial with your real glass or backsheet and your module's electrical design, whatever the general outdoor-use wording says. [2]
Lock the approved build
Agree component and finished-module tests. Keep lot, drawing, material and process records, and require written approval for any substitution that changes the qualified build. [2]
Writing the enquiry
Give Jiaming enough detail to quote PV-JM807 properly
Start from your module's current
Send the module design and the qualification route you follow. Ask whether PV-JM807 suits it or whether a different documented model fits better. The entry is rated 1000 V DC, so ask for another model if you need 1500 V or a high-current box. [2]
Project fit
Match the offering to your project
Module makers buying a defined junction box together with its diode and cable set.
Engineers comparing a 1000 V DC box whose current depends on the diode fitted.
Buyers who want the PV supplier kept apart from the group's valve and equipment businesses.
Confirm before ordering
- Which diode and test conditions sit behind the 6A row, and the exact variant number.
- A current TÜV certificate with model annex, the full drawing with tolerances, and the assembly instructions.
- The plant that will produce your order and the scope of the PV laboratory's test reports.

When was the PV company founded?
In 2005, according to the company timeline. The 1987 date belongs to the metal business. [1]
Do the valve licences on the website cover junction boxes?
They belong to the valve business. Ask Jiaming for the PV component certificates and test reports for the box you order. [1]
Is PV-JM807 rated for 1500 V DC?
The product page gives 1000 V DC. For a 1500 V module, ask Jiaming which of its models is documented for that voltage. [2]
Does the 6A row cover every diode option?
Jiaming says the diode choice changes the current but lists no combinations. Ask for the rating definition that goes with your configuration. [2]
