Pair of Solar 3 to 1 Connectors Branch/Splitter, Parallel PV Panel MC4 Connector
Pair of Solar 3-to-1 Connectors Branch/Splitter (Parallel PV Array) MC4
This pair of Quad (4-to-1) T-Branch Solar Connectors is the perfect solution for connecting multiple solar panels together in a parallel configuration. Manufactured by CraigSolar.co.uk, these splitters are made from high-quality, durable materials designed to withstand harsh outdoor environments while keeping your solar array wiring organized and highly efficient.
Engineered for heavy-duty use, these connectors boast an impressive 50A rated current and 1500V rated voltage capacity. Whether you are building an off-grid cabin setup, expanding an RV solar system, or wiring a home power backup, these easy-to-use connectors provide a reliable, low-resistance connection for your photovoltaic panels.
Safety & Installation Warning: Always disconnect or cover solar panels before making electrical connections, as panels produce live voltage whenever exposed to light. Ensure your charge controller and wiring are rated for the combined amperage of a 3-panel parallel setup.
Key Features
- 4-to-1 Branch Design: Seamlessly combines the output of up to four solar panels into a single positive and negative cable run.
- Parallel Wiring Optimized: Perfect for maintaining panel voltage while securely combining the available current.
- High Capacity: Rated for a maximum current of 50A and an impressive 1500V, making it suitable for large-scale or high-output arrays.
- Extreme Weather Resistance: IP67 water-resistant rating ensures complete protection against heavy rain, dust, and environmental exposure.
- Ultra-Low Resistance: Features a contact resistance of <0.5 ohms to ensure maximum power transfer efficiency and minimal energy loss.

Important Installation Notes
- Amperage Limits: When wiring 3 solar panels in parallel, the total system voltage remains the same, but the current (amperage) of all four panels is added together. Verify that your system's wiring, fuses, and charge controller are rated to handle the total combined current output.
- Compatibility: These adapters feature standard solar connector interfaces. Always ensure the locking tabs securely click into place with your existing panel leads to maintain the IP67 weather seal.
