2 to 1 MC4 Compatible Solar Branch Connector 1500V
Last updated: November 2026
Where two strings already run together, this 2F/M connector merges them at the end of the row: 123 mm tall, 1500 V DC under TÜV and UL, 60 A at the output. That rating is far more than two ordinary strings draw, so current is not the constraint on this model.

Product Overview
About the 2 to 1 MC4 Compatible Solar Branch Connector 1500V
Treasol 2 to 1 MC4-compatible branch connector merges two 1500 V DC strings into one output. Rated 1500 V under TÜV and UL at 60 A, IP68 sealed, in a 123 mm tall body that fits inside a module row.
Key Features
Two inputs merged into one moulded body, instead of a field-made joint.
1500 V DC rated under TÜV and UL.
60 A at the combined output — the widest headroom of the range.
Contact resistance below 0.5 mΩ keeps joint losses and heat low.
PPE housing, UL 94 V-0, Safety Class II: no DC-side earth needed.
IP68: continuous immersion under the stated test conditions.
Rated -40 °C to +85 °C ambient.
MC4-compatible interface, checked to IEC 62852 (2014 + AMD1:2020).
The 2 to 1 is the model to pick when two strings already run close together and only the last stretch needs merging. At 123 mm tall and 85.5 mm long it sits inside most module-row gaps, so the pair can be paralleled at the end of the row rather than pulled back to a combiner as two separate runs.
The 60 A figure applies to the combined output, not to each input, which is why this model carries the most headroom: two strings would have to draw 30 A each before the ceiling is reached, well above typical string currents. Electrical ratings are 1500 V DC under TÜV and UL with a 12 kV test voltage and contact resistance below 0.5 mΩ. The PPE body is UL 94 V-0 and Safety Class II, so no protective earth is needed on the DC side, and it is IP68 sealed across -40 °C to +85 °C. The interface is MC4-compatible; check the counterpart against IEC 62852 (2014 + AMD1:2020) before mating.

Compatibility
MC4-compatible PV connection design
2 to 1 MC4 Compatible Solar Branch Connector 1500V uses an MC4-compatible mating interface. Final compatibility depends on the counterpart connector; check its datasheet and the applicable connector standard before installation.
Connector compatibility
Model: 2 to 1 Branch Connector 1500V
Product Type: Solar Branch connector
Compatibility Type: MC4-compatible solar cable connector
For safety and certification compliance, connectors from the same manufacturer and approved connector combinations should be used within the same PV connection system. Mixing connectors from different manufacturers should only be considered when compatibility has been verified and permitted by the applicable certification requirements.

FAQ
2 to 1 MC4 Compatible Solar Branch Connector 1500V frequently asked questions
Technical answers for product selection, cable matching and PV connection design.
What is a 2 to 1 solar branch connector?
It merges two PV strings into a single output at one point, so one cable instead of two runs back to the combiner. The 2F/M model here is the smallest body in the Series-2 range at 123 mm tall.
What is the rated voltage?
1500 V DC, with both TÜV and UL ratings at that level. It belongs to the Treasol Series-2 branch connector range.
How many strings can the 60 A output carry?
The 60 A limits the sum of the input currents. With two inputs, each string could draw up to 30 A before the ceiling is reached, so this model is not current-limited in practice for ordinary string currents.
Is it MC4 compatible?
The mating interface is MC4-compatible. Compatibility is a property of the pair, so check the counterpart connector against IEC 62852 (2014 + AMD1:2020) and its own datasheet, including dimensions and ratings, before assembly.
What does IP68 mean on this connector?
Under IEC 60529, IPX8 means continuous immersion under conditions the manufacturer states — it is not an open-ended depth rating. The seal also depends on correct mating and cable assembly, so ask for the stated test condition if the installation is exposed.
What is the housing material?
PPE, rated UL 94 V-0 and Safety Class II. PPE holds its dimensions and dielectric strength in humid outdoor service, which matters for a moulded body that has to keep its seal over years.
What is the operating temperature range?
-40 °C to +85 °C ambient.
Why not just use a Y-branch joint?
A Y-joint is two cables spliced together; this is a moulded body with a defined IP rating and a 60 A current path. Where the joint has to stay sealed and inspectable, the moulded part is the more predictable choice.
What does 2F/M mean in the model code?
2F/M denotes a 2 to 1 branch configuration, and F/M identifies the gender arrangement of the connectors. Confirm the exact mating layout on the drawing, or with Treasol, before ordering.
Can Treasol supply OEM versions?
Yes. Send the required configuration, cable specification, technical requirements and estimated quantity to the sales team to discuss OEM options.
