Zhejiang Zhonghuan Sunter PV Technology
浙江中环赛特光伏科技有限公司
Since 2004 this Cixi company has built junction boxes, connectors and cables for PV modules. Its PV-ZH011C-5 split box pairs each current rating with a named diode and comes with three-position drawings, so a quote can name the full assembly from the start.

Company scope
What the company makes
浙江中环赛特光伏科技有限公司 trades as Zhonghuan Sunter and has made PV junction boxes, connectors and cables since 2004. It runs mould making, injection moulding, stamping, automatic assembly and a test laboratory. Production is split between Zhejiang and Vietnam, and a subsidiary makes composite module frames. The website gives group-wide equipment counts and daily output; ask what capacity and lead time apply to your own order.
PV-ZH011C-5 is a split junction box with three separate positions, cabling and a connector pair. Zhonghuan Sunter's technical sheet lists 1500 V DC, four current ratings each tied to a diode, and real dimensions for every box. That gives an engineer enough to open a drawing and configuration discussion straight away.
Jetion's module manual from February 2024 names Zhonghuan Sunter and PV-ZH011C-5 in its junction-box tables, with diode entries for 22A and 25A. It shows the box in use on a module maker's line. For 18A, 30A, a different module or another connector, ask Zhonghuan Sunter for documents covering that combination. The company lists TÜV, UL and other approvals in general terms, so request certificates that name the model and the producing site.

Start with the actual equipment
The entries below cover selected products and series from this manufacturer. Ask for the full catalogue if your project needs other models.
PV-ZH011C-5 split PV junction-box assembly →
PV-ZH011C-5 is a split junction box with left, centre and right positions. The outer boxes carry the outgoing cables and connectors; the centre box is shorter and has its own terminal layout. It is rated 1500 V DC in 18A, 22A, 25A… [2]
Specifications & selection questions →In-house production
Zhonghuan Sunter moulds, stamps and assembles its own boxes
Moulding and contacts
The company runs mould making, injection moulding, stamping and automatic assembly. Ask which polymer, contact material and process controls apply to the revision you order, and how each lot is traced. [1][4]
Zhejiang and Vietnam
Two production locations are described, with combined capacity figures. Ask which plant will build your boxes, who releases them and what that plant is approved to make. Write a capacity figure for this box into the contract. [1][4]
Frame subsidiary
A subsidiary produces composite frames. Junction-box approvals sit with the electrical side of the business, so ask for those separately if you buy both. [1]
PV-ZH011C-5
PV-ZH011C-5 comes in four current versions, each with its own diode
| Version | Zhonghuan Sunter sheet | Jetion manual, February 2024 |
|---|---|---|
| 18A | 25SQ045 diode | No 18A line for this model. |
| 22A | 30SQ045; the diode line also says 20–22A | 30SQ045 for 22A. |
| 25A | 35SQ045 | 35SQ045 for 25A. |
| 30A | 40SQ045 | No 30A line for this model. |
The rated-current line lists 18, 22, 25 and 30A; 20A appears only in the diode row. Ask which version the 20–22A wording refers to. [3][5]
Fit to your module
The outer and centre boxes have different dimensions
Box sizes
Each outer box is drawn at 66.50mm and the centre box at 52.70mm, both 23.90mm wide and 17.10mm high in side view. Lids measure 56.80 by 28.35mm. Ask for the controlled drawing with datums, tolerances and the full installation envelope. [3]
From model name to purchase order
Ask for documents that cover your version and its plant
Choose the electrical version
Send your module voltage and current and ask for the matching diode, temperature conditions and controlled bill of materials. The 30A version needs its own approval documents, since the Jetion manual stops at 22A and 25A. [3][5]
Collect certificate annexes
The website mentions TÜV, UL and other approvals in general. Request certificate numbers, holder, factory, construction and coverage for the version you pick. [4][3]
Agree assembly and tests
Get the approved instructions for module bonding, ribbon connection, sealing and curing. Set the component and module tests and their pass criteria for your materials and process. [3][5]
Trace every lot
Record drawing revision, box positions, polymer, diodes, terminals, cable and connector lots. Agree sample release, lead time, packaging and change notice, with capacity for this box written into the order. [1][3]

Does the Jetion manual cover all four current ratings?
Its diode table lists 22A and 25A for this model. The Zhonghuan Sunter sheet adds 18A and 30A, so ask for documents covering those. [3][5]
Is 20A a fifth version?
The rating line stops at four values. The 20–22A wording sits in a diode row, and Zhonghuan Sunter can clarify it. [3]
How far does IP68 go?
The stated condition is 1m for 1h. Ask the factory about any longer immersion your installation requires. [3]
