Step 6: Install Fuses or Close Breakers
Install a properly sized DC-rated fuse in each fuse holder
in the following order:
1. Load circuit
2. Battery circuit
3. Solar circuit
Refer to the fuse table on page 46 for appropriate fuse sizes
If using circuit breakers, close the load breaker first
followed by the battery breaker, then the solar breaker.
Step 7: Confirm Power-up
The SunSaver should begin the power-up LED sequence
when battery power is applied. Observe that the Battery
Status LEDs blink in sequence one time.
If the SunSaver does not power up or a flashing LED error
sequence exists, refer to
Section 5.0 Troubleshooting.
