Last updated: November 2026
The longest body in the range at 144.6 mm, built to take five strings into one output. Sharing 60 A across five inputs averages 12 A each, so string current decides whether the 5F/M fits the array.

Product Overview
About the 5 to 1 MC4 Compatible Solar Branch Connector 1500V
Treasol 5 to 1 MC4-compatible branch connector takes five 1500 V DC strings into one output. Sharing 60 A across five inputs averages 12 A each, and the 144.6 mm body is the longest in the range.
Key Features
Five inputs on one body, replacing four Y-joints and four home runs.
1500 V DC rated under TÜV and UL.
60 A combined output, i.e. 12 A per input when all five are loaded.
Contact resistance below 0.5 mΩ.
PPE housing, UL 94 V-0, Safety Class II.
IP68 sealing under the stated immersion conditions.
Rated -40 °C to +85 °C ambient.
144.6 mm body, the longest in the range; MC4-compatible interface.
Five strings is where layout convenience and current budget start to pull against each other. The 5 to 1 removes four Y-joints and four home runs, and its 144.6 mm body is the longest in the range, so it needs a little more room along the rail than the 3F/M or 4F/M.
The 60 A output is shared across five inputs, which works out to 12 A per string if all five are loaded equally — fine for many string designs, tight for high-current modules. Ratings are 1500 V DC under TÜV and UL, 12 kV test voltage and contact resistance below 0.5 mΩ. Housing is PPE, UL 94 V-0 and Safety Class II; sealing is IP68 over -40 °C to +85 °C. Five paralleled strings also mean five reverse-feed paths, so string-level overcurrent protection remains an array-design decision. The MC4-compatible interface should be matched to the counterpart per IEC 62852 (2014 + AMD1:2020).

Compatibility
MC4-compatible PV connection design
5 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: 5 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
5 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 5 to 1 solar branch connector?
It merges five PV strings into a single output at one point. It removes four Y-joints and four separate home runs, at the cost of a longer body and a tighter current budget.
What is the rated voltage?
1500 V DC under TÜV and UL ratings. This is the 5F/M model of the Treasol Series-2 branch connector range.
Five strings on a 60 A output — is that enough?
Only if the string currents are low enough. 60 A shared across five inputs averages 12 A each; five strings at 15 A would total 75 A and exceed the rating. Add the currents before choosing this model over the 3F/M or 4F/M.
How much room does the body need?
The body is 144.6 mm long overall, the longest in the Series-2 range, so allow for it along the rail or in the cable tray. The drawing gives both views.
Is it MC4 compatible?
The mating interface is MC4-compatible. Compatibility depends on the counterpart, so check it against IEC 62852 (2014 + AMD1:2020) and its datasheet.
What does IP68 cover?
Dust-tight plus protection against continuous immersion under conditions stated by the manufacturer, per IEC 60529 — not an unlimited depth claim, and dependent on correct mating.
What is the housing material?
PPE, UL 94 V-0 and Safety Class II. PPE resists moisture-driven dimensional change, which helps a moulded body keep its seal.
What is the operating temperature range?
-40 °C to +85 °C ambient.
Do five paralleled strings need fusing?
String-level overcurrent protection should be sized as part of the array design (IEC 62548, NEC 690.9 in the US). A faulted string can be back-fed by the other four; the connector carries current but does not interrupt a fault.
What does 5F/M mean?
The code for a 5 to 1 branch configuration with the F/M gender arrangement. Check the drawing for the mating layout before ordering.
