Company scope
What the company makes
Zhejiang Renhe Photovoltaic Technology (浙江人和光伏科技有限公司) develops and produces junction boxes, connectors, cables and related parts for PV modules. Its contact page gives an address in Cixi. The part covered here is the GF50xy junction box for crystalline-silicon modules. It is a component your module line installs; stringers, box-assembly machines and installation work fall outside this listing.
Renhe publishes four images for the family: a product photo, an outline drawing, a technical data table and a diode table. The two certification columns differ. TÜV lists 4 mm² cable while UL lists 12 AWG, and each column has its own current and diode rows. Keep the column you need on the purchase order.
Renhe describes itself as vertically integrated across its components, with a laboratory of its own. When you quote, ask for current output figures and for the company and product certificates that apply to your part.
Two outside sources add context. China's national standards platform names Renhe among the drafters of GB/T 37410-2019, a standard still valid after its 2025 review. DEKRA announced in June 2024 that Renhe had received CB certificates for junction boxes and connectors. Ask Renhe for the current certificates and the complete model annexes that list your GF50xy variant.

GF50xy PV module junction-box family →
GF50xy is Renhe's potting-sealed junction box for crystalline-silicon modules, rated 1500 V DC in both its TÜV and UL columns. It uses three diodes, with 13–16 A TÜV rows or a 20 A UL row, takes soldered ribbon up to 8 mm… [2]
Specifications & selection questions →What goes into a GF50xy order
Renhe GF50xy: specify the whole box assembly
Diodes and circuit
The family table shows three diodes and several current and diode-type combinations. The table leaves the x and y in the name open, so ask Renhe for the full suffix, the diode maker and designation, and a controlled circuit drawing. [2]
Cable and connectors
TÜV and UL cable sizes appear in separate columns, and connector options are grouped by approval and voltage. Put the supplied connector, the mating connector, cable length and termination in the order, and get the approval that covers that exact pair. [2]
Ribbon, potting and bonding
GF50xy takes soldered ribbon up to 8 mm wide and holds about 28 ml of potting compound. Settle your ribbon geometry, the box bonding surface and the approved sealant and cure process with Renhe. Use the 28 ml as a guide figure and agree your own dosing tolerance. [2]
Certificates and standards
What Renhe's certificates and standards work cover
| Source | What it says | Ask Renhe for |
|---|---|---|
| GF50xy data table | 1500 V DC in both columns, with TÜV and UL certificate numbers. | The current certificate and annex covering your diode, cable and connector. |
| SAMR standards record | GB/T 37410-2019 is current, with Renhe named as a drafter. | Test reports showing your quoted part meets the standard. |
| DEKRA, June 2024 | Renhe received CB awards for junction boxes and connectors. | Present validity, and whether your configuration is listed. |
| Renhe company page | Own laboratory and an integrated supply chain. | Facility details, scope, current output and audit records. |
A standards role, a 2024 award and a catalogue certificate number each answer a different question. Match the certificate annex to your order line. [2][4][5][1]
From component to finished module
Soldering, bonding and potting the GF50xy on your line
Check the physical fit
Work from the outline and terminal drawing for your variant. Confirm ribbon position, exposed length, routing and free space on the module with Renhe, because the body size only gives the footprint. [2]
Approve parts and joining method
Fix the diode and current combination, ribbon, cable and connectors. Ask Renhe for its recommended soldering and bonding instructions, since the general catalogue table carries no temperature settings. [2]
Qualify potting and cure
Use the potting system and backsheet adhesive that Renhe approves. On real boxes, define dose, coverage, cure, void checks and release criteria. [2]
Test and freeze the variant
Agree component and module checks, including polarity, connection quality and environmental and electrical qualification. Record component lots, and require approval before any change to diodes, plastics, connectors or process. [2][5]
Reading the ratings
How far the GF50xy catalogue ratings reach
IP rating and immersion
The table gives IP65/IP68 with a 1 m, 1 h immersion note. For long immersion or offshore sites, ask how enclosure, potting and connectors are qualified. The offshore FT50xy on the same website is a separate product with its own data. [2]
Current depends on the diode row
TÜV rows run from 13 to 16 A, and the UL column has one 20 A row covering several diode types. Quote the exact rating and certificate for the diode you will receive, and agree up front that diode substitutions need your approval. [2]
Project fit
Match the offering to your project
Module makers building a traceable junction-box, cable and connector set.
Buyers who need TÜV or UL configurations kept apart down to the diode and current row.
Plants able to run their own soldering, bonding and potting trials on real modules.
Confirm before ordering
- Full GF50xy suffix, current certificate annexes and the quoted diode and connector set.
- Renhe's approved instructions for soldering, box bonding and potting cure.
- The producing site, plus a production audit if your quality system calls for one.
Renhe's catalogue images, company and contact pages, the SAMR standard record and DEKRA's 2024 notice were all checked in October 2026.
