Connecting Panels in Parallel
The solar 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 mul-
tiple panel systems, plug into the MC4 T Branch connectors. Panels can be connected
in parallel (+ to + and - to -), but never connect panels in series because this may result
in a voltage that is too high for the charge controller. Below are some diagrams showing
parallel connections:
