Step 1: Hook up the battery to the charge controller.

Connect the battery terminal wires to the charge controller FIRST, then connect the solar panel(s) to the charge controller. For detailed reasons, see Should We Connect Batteries First Instead of Solar Panels to Charge Controllers?

You could use our tray cable or any general stranded copper core wire to connect the two. Make sure that you lead the wire into the battery terminal of the charge controller and match the + and – to the battery + and -. Make sure to screw in the exposed wire tightly inside the controller terminal. Then screw on the battery rings to the battery. See Figure 1.

Step 2: Connect your solar panel to your charge controller.

We recommend that you connect the adapter kit to your panel first, then follow the + or – sign coming off of the leads of the panels and match it with the + and – sign on the charge controller. See Figure 2.

Step 3: Hook up your inverter to your battery by using battery ring cables and by matching the + to + and – to -.
