• Suitable cable (See table 2 for recommended cable sizes)

• Correct rated fuse or circuit breaker

1. Connect a fuse or circuit breaker to the positive terminal of the battery, (As near to the battery as possible)

refer to Fig. 8. Leave the fuse out.

2. Connect a cable from the fuse or circuit breaker to the solar controllers’ positive terminal.

3. Connect a cable from the battery’s negative terminal to the solar controller’s negative terminal.

4. Connect both solar panels to the solar controller. Ensure positive to positive and negative to negative.

Refer to Figure 8.

Note: More than two solar panels can be added in parallel by simply repeating steps 4 and 5. Depending on

the number of Solar panels added choose a solar controller, fuse and cabling between the battery and solar

controller that will handle the increased current.
