Mount the additional 50-watt solar panel  so that it is facing due South at approximately the same angle as
your latitude. The ideal area has full sun and no shading. If the following connections are made during daylight,
cover all panels with cardboard, cloth, or a similar opaque material so that the panels do not output power.
Connect the In-line MC4 Fuse  to the positive lead
of the new 50-watt solar panel . Disconnect the
MC4 connections of the original panel, and insert
Branch Connecters  into the resulting gap. Use the
16-inch MC4 cables  to connect the 50-watt solar
