QUICK START GUIDE
STEP 1. Connect the ring lugsto your 12V deep
cycle battery. This controller supports common lead
-acid battery types including AGM/Gel/Flooded.
If your battery has sufficient charge, the battery LED
indicatorshould light up solid.
STEP 2. Connect the MC4 style solar connectors
to a 12V solar panel rated no more than 150 watts.
As the battery charges, the solar LED indicator
should begin to slowly flash.
When you need to disconnect the system, reverse
these previous steps by disconnecting the solar
panel first, then disconnecting the battery.
