Overview

2-to-1 Y-branch adapter cables for wiring two solar panels in parallel

Standard MC4-compatible solar connectors plug in and come apart without special tools, and tinned copper conductors with TPE / PPO insulation work from -40°F to 194°F. Rich Solar lists them for RVs, campers, off-grid systems and portable solar setups.
