EQUIPMENT MODEL
PV-Y30m · Yitong PV-Y30m split junction box
Yitong Tech ↗Three-housing split junction box with three diodes for PV modules. Confirm the model code with Yitong, then set the current option, connector and potting.
Covers the PV-Y30m webpage and the linked drawing, which is labelled PV-YT30m. The ratings are catalogue values; request the certificate annex and module test results with the quote.
General illustration of module assembly equipment, not a photograph of this model. Ask the manufacturer for current photographs and layout drawings of the configuration offered.
START WITH YOUR PRODUCTION TASK
Confirm the model code and drawing revision, choose the current and diode option, then qualify ribbon joints, potting, cable and connector, and the module's electrical and thermal behaviour.
SOURCE-LINKED DATA
Published specifications
Values below are published by the manufacturer, each with the date its source was checked. Ask for the figures that apply to your configuration and material in the quotation.
The manufacturer has not published a complete specification table for this entry. Request the exact offered drawing and operating limits.
01 · Manufacturer information
PV-Y30m or PV-YT30m: settle the code first
The webpage drops the T that appears in the PDF's product-number row and on the housing markings. Treat the two labels as separate until Yitong says they match. Ask for the current ordering code, the controlled drawing revision and the certificate annex that belongs to it.
The drawing shows three housings wired in a three-diode circuit. It lists 20 A and 25 A ratings next to TM3045-20 and TM3045-25 diodes. Pick one current and diode configuration and ask for the operating and test conditions behind it.

Housing sizes, potting amount and connector code
Two housing sizes
The table lists 71.76 × 23.4 × 13.9 mm and 76.96 × 23.4 × 13.9 mm, and the drawings place the housings in different positions. Ask for the full position drawing with spacing and installation rules.
Potting amount left blank
The silicone-gel row reads only “APPr.” with no number. Ask Yitong for the material, fill mass or volume, dispensing path, cure and inspection criteria.
A specific connector code
The optional connector is listed as YT08-1A and 18-01. Order that exact pair with its qualified cable assembly; a similar-looking connector from another brand needs its own mating approval.

Qualify the whole module connection
Fix model and configuration
Settle the model letter and drawing revision, then specify current, diodes, housing material, cable and connector pair, and collect the current certificate annex.
Match ribbon routing
Send the module's output ribbons, polarity, ribbon widths and thicknesses and exit layout. Check the 20 mm terminal spacing and each housing position on your laminate drawing.
Set soldering and potting
Agree the joint process, sealant type and amount, cure, and checks for voids and coverage. The sheet gives no complete gel volume or standard recipe.
Test electrical and thermal behaviour
Agree bypass-diode, insulation, connection and environmental tests on your module with the chosen configuration. A module running above 25 A needs its own assessment beyond the catalogue option.
Keep assemblies traceable
Record lot, diode, cable and connector identities, drawing revision and test data. Review any substitution or process change before releasing production.

What to send with a PV-Y30m enquiry
Model code
Ask whether PV-Y30m and PV-YT30m are the same current product, and request the ordering code with its document revision.
Electrical data
Give module voltage, current, circuit and output polarity. State which current and diode option you are assessing and ask for its qualification conditions.
Mechanical layout
Attach laminate and ribbon-exit drawings, housing positions, cable length and connector pair. The product photo is no guide to cable length.
Potting and certificates
Ask for the fill quantity, approved potting material and process, current certificate number and annex, and the IP test conditions.
Shipment terms
Agree assembly marking, lot records, supplied options and inspection tests. Ask Yitong to quote price, stock and lead time.

PV-Y30m questions to put to Yitong
Are PV-Y30m and PV-YT30m one product?
The webpage and drawing use different labels. Yitong needs to confirm in writing which code to order.
Is the box TUV certified today?
The PDF shows TUV but no certificate number or annex. Ask for both and check that they cover your configuration.
How much potting gel does it take?
The drawing leaves the amount blank. Yitong should state the material, fill quantity and controlled process.
Can I fit a different connector that looks compatible?
Only with a mating approval for that pair. Order the qualified connector pair and cable configuration.
Does IP68 mean any immersion depth or time?
No. Ask for the test conditions and scope that apply to the assembled configuration you choose.
