Connecting Panels in Parallel
The GS-S-100-Fab36 panel comes with 900mm MC4 leads, one for positive + and the
other for negative -. The connectors plug into the MC4 leads for the Charge Controller,
or in multiple panel systems, plug into the MC4 T Branch connectors. Panels can be
connected in parallel (+ to + and - to -) or in series (+ to -), but never connect more than
two panels in series because this will result in a voltage that is too high for the charge
controller. Below are some diagrams showing parallel connections:
