1. Connect the singular end of the branch connector (Duralite part #10) to the solar controller.

2. Place the solar controller (Duralite part #3) on the leg of the main solar kit using the Velcro fastener provided.

3. Connect the expansion cable (Expansion part #4) to the DC port (Duralite part #10) of the expansion panel.

4. Connect the other end of the expansion cable to the branch connector.

5. Repeat if connecting another expansion panel.

You do not need to utilize all 3 connections on the branch connector for the expansion kit to function. Connections are to be made red to red, black to black. You will hear a “click” when the connection has been made properly.
