Stäubli MC4 Y-splitter set (plus & minus) – PV-K/SPL-Y-6-15/15-15EPP (ES-0050)

Want to put two PV strings in parallel (2→1) or just split one string (1→2) with reliable, original MC4 quality?
Then you’re in the right place with this Stäubli Y-splitter set. We supply this product as a complete set:
1× Y-splitter for the plus (+) and 1× Y-splitter for the minus (-). So you immediately have a correct and symmetrical connection to your PV string(s).

MPN / identification

  • MPN: PV-K/SPL-Y-6-15/15-15EPP/
  • Code: ES-0050
  • Delivery: set consisting of 1× + and 1× – Y-splitter

What do you use an MC4 Y-splitter for?

  • Parallel switching of strings (2→1): merging two strings to one input (e.g. inverter/MPPT or string box).
  • Splitting (1→2): one string to two connections (only use if your design really requires it).
  • Neat and service-friendly: no “tinker coronets”, but click-proof MC4 connections that hold their ground even outdoors.

Technical properties (important in practice)

  • Cable cross-section: suitable for 6 mm² PV cable (as indicated in the type code)
  • Current: 15 A (per branch as per type code)
  • Connector family: Stäubli / MC4 compatible (original quality)
  • Application: DC side of PV installations (outdoor/UV/moisture-resistant – if fitted correctly)

Installation tips (to get it right the first time)

  • Always use as a set: parallel always involves + and –. This is why we supply this as a complete set.
  • Strings must be “equal”: only combine strings with equal panel numbers, same type of panels and same orientation/shade profile. Otherwise you get yield losses and unnecessary equalisation currents.
  • Check reverse current/fuse requirements: parallel strings may require string protection (fuses), depending on number of parallel strings, panel specifications and design rules.
  • Click = click: make sure connectors lock fully (do pull test), and avoid mechanical stress on cables.
  • Work de-energised: DC remains dangerous. Switch off, measure and work cleanly.

What’s in the package?

  • 1× Stäubli MC4 Y-splitter for plus (+)
  • 1× Stäubli MC4 Y-splitter for minus (-)

In short: one complete, professional set to connect PV strings safely and tightly in parallel – exactly how you want to see it on a roof (or in a string box).
