Overview
4-to-1 Y-branch connectors for wiring four solar panels in parallel
Rich Solar's RS-T4 Y-branch connectors join four solar panels in parallel. They are rated 30A and 1000V DC, fit 10 AWG and 12 AWG wire, and are IP67 waterproof and dustproof.
The plug-and-play design installs quickly without extra tools, and tinned copper contacts give low contact resistance for a reliable, efficient connection. The PPO + PA housing works from -40°F to +194°F.
