## Long description

Pair of MC4 Y solar splitter adapters from Victron Energy, model SCA520500000. This set contains two complementary MC4 Y-connectors (one male-to-2-female and one female-to-2-male) designed to enable parallel connection or convenient branching of photovoltaic cables. The adapters maintain MC4 compatibility for easy integration into existing PV arrays and are intended for use with standard MC4-equipped solar modules and wiring.
Advantages
These Victron Energy MC4 Y adapters provide a straightforward way to split or combine MC4-connected cables without the need for crimping or additional tools. Constructed to preserve secure electrical contact and polarity, the pair supports common rooftop and ground-mounted PV installations while minimizing connection complexity. The matched male and female Y pieces allow flexible routing and reconfiguration of strings during installation or maintenance.
Suitable for
Combining two solar module strings in parallel
Branching a single string to feed multiple microinverters or optimizers
Temporary or permanent cable routing changes during PV installation
DIY solar projects requiring MC4-compatible connectors
Key specifications
Connector type: MC4 Y-adapter pair (one male-to-two-female, one female-to-two-male)
Contact material: corrosion-resistant metal contacts for reliable conductivity
Insulation and housing: UV-resistant plastic suitable for outdoor PV use
Maximum recommended current and voltage: conforms to common MC4 system ratings used in residential and commercial PV (refer to system inverter and cable ratings when designing)
Mounting and installation: inline plug-and-play connectors compatible with standard MC4 cables
How to use
Identify the positive and negative MC4 leads on the PV cables and ensure system DC power is disconnected before making any connections. Plug the male and female MC4 ends of the adapters into the corresponding MC4 plugs on the cables or modules, verifying secure locking clicks. Use the male-to-two-female or female-to-two-male pieces as required to split or combine circuits, making sure polarity is preserved when paralleling strings. After connecting, visually inspect each locking tab and contact point, and restore system DC power only when all connections are secure and properly routed.
Usage recommendations
Use these MC4 Y adapters only with compatible MC4 cables and within the electrical limits of your PV system. Confirm inverter, optimizer, and panel specifications before paralleling strings, and avoid creating unintended reverse-polarity or excessive current paths. For permanent installations, ensure connectors remain accessible for inspection and consider additional protection against mechanical strain and water ingress where necessary.
