5 to 1 MC4 Compatible Solar Branch Connector 1000V
Last updated: November 2026
Five strings into one output in the widest body of the 1000 V range at 100.8 mm. The 45 A ceiling is the tightest here: five inputs only fit if each string stays at 9 A or below.

Product Overview
About the 5 to 1 MC4 Compatible Solar Branch Connector 1000V
Treasol 5 to 1 MC4-compatible branch connector takes five 1000 V DC strings into one output. 45 A across five inputs averages 9 A each; 96.4 mm body, 100.8 mm wide, IP67.
Key Features
Five inputs on one body, replacing four Y-joints and four home runs.
1000 V DC rated under TÜV and UL.
45 A combined output: 9 A per input when all five are loaded.
Contact resistance below 0.5 mΩ.
PPE housing, UL 94 V-0, Safety Class II.
IP67 to IEC 60529 IPX7: 30 minutes at 1 m depth.
Rated -40 °C to +85 °C ambient.
100.8 mm wide, the widest in the range; MC4-compatible to IEC 62852.
The 5 to 1 is for arrays that want five parallel strings gathered without stacking Y-connectors four deep. It removes four joints and four home runs, but its 100.8 mm width is the widest in the range, so check the space along the rail before committing.
Shared across five inputs, 45 A averages 9 A per string — a narrow window that rules the model out for most 15 A string designs. Where the strings are lower-current, it collects five runs into one at a single point. Electrical ratings are 1000 V DC under TÜV and UL, an 8 kV test voltage and contact resistance below 0.5 mΩ. The PPE housing is UL 94 V-0 and Safety Class II, sealing is IP67 (IEC 60529 IPX7) and the range is -40 °C to +85 °C. Five paralleled strings mean five reverse-feed paths, so string-level overcurrent protection is sized within the array design; the connector does not interrupt current. Check the interface against IEC 62852 (2014 + AMD1:2020).

Compatibility
MC4-compatible PV connection design
5 to 1 MC4 Compatible Solar Branch Connector 1000V 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 1000V
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 1000V 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, removing four Y-joints and four separate home runs. At 100.8 mm it is the widest body in the 1000 V range.
What is the rated voltage?
1000 V DC under TÜV and UL ratings. This is the 5F/M model of the Treasol 1000 V branch connector range.
Five strings on a 45 A output — is that enough?
Only for low-current strings. 45 A shared across five inputs averages 9 A each; five 15 A strings would total 75 A, two thirds over the rating. Add the string currents before choosing this model over the 3 to 1 or 4 to 1.
How much room does the body need?
The body is 96.4 mm long and 100.8 mm wide, the widest in the range, so allow for that along the rail or in the cable tray.
Is it MC4 compatible?
The interface is MC4-compatible. Compatibility depends on the counterpart, so check it against IEC 62852 (2014 + AMD1:2020) and its datasheet.
What does IP67 cover?
IEC 60529 IPX7 covers 30 minutes of immersion at 1 m under the stated conditions, not continuous immersion. Correct mating and cable assembly are required for the seal to hold.
What is the housing material?
PPE, UL 94 V-0 and Safety Class II. PPE resists moisture-driven dimensional change, which helps the 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.
When should a 1500 V connector be used instead?
At the same power a 1000 V circuit carries about 1.5 times the current, so the 45 A ceiling is reached with fewer strings. The Series-2 branch connectors carry 60 A at 1500 V DC.
