WIRING CONNECTIONS
To protect the battery and solar panel, it is recommended that you place an inline fuse on the
positive wire of both the ‘Solar’ and ‘Battery’ circuits. A 20A fuse is required and should be installed
as close to the battery/solar panel as possible.
The Solar Controller has 4 terminals which are clearly marked ‘Solar’ and ‘Battery’.
There is a (12V) and earth (GND) terminal for each circuit.
Refer to the wiring diagram below.
1. Using the string wires, tightly screw the wires to the “Solar” terminal on the back of the
controller and connect to the solar panel as shown above in Fig 3.
2. Using the string wires, tightly screw the wires to the “Battery” terminal on the back of the
controller and connect to the battery as shown above in Fig 3.
When the connections are completed, the Solar Controller will start working automatically.

Correct Wire Size:
Please refer to the wire size chart below to
determine the minimum size wire needed
for each connection. This will also ensure
you get the best performance out of
your solar regulator.
