ROCKSOLAR 4-to-1 Solar Branch Connectors MMMMF + FFFFM pairA pair of MC4 branch connectors that joins four solar panels in parallel into one positive and one negative lead: four 100 W to 200 W panels on an RV or cabin roof feeding one charge controller. IP67 sealed UV-resistant snap-lock.Panels wired in parallel keep the array at one panel's voltage and add the currents together which is the right layout for a PWM controller a 12 V or 24 V battery bank or any MPPT whose open-circuit limit rules out a series string.
