The Jackery Y-parallel adapter is exclusively used for connecting two solar panels by parallel on the Explorer 1000 via the Anderson port for faster recharge. If you only have a single solar panel, you can directly plug it into the 8mm input port. You cannot plug three solar panels simultaneously into the 8mm input port and the Anderson port because the Explorer 1000 does not support dual input.
Is the Y-parallel adapter used to connect 1 or 2 solar panels?
