Overview
4-to-1 Y-branch adapter cables for wiring four solar panels in parallel
Rich Solar's RS-Y4 Y-branch adapters combine four solar panel leads in parallel into a single output. The 12 AWG leads are rated 20A and 1000V DC, measure 22 in overall, and carry an IP67 rating.
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.
