QUICK START GUIDE

STEP 1. Connect the ring lugs ➋ to 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 indicator ➍ should light up solid.

STEP 2. Connect the MC4 style solar connectors ➊ to a 12V solar panel rated no more than 150 watts. As the battery charges, the solar LED indicator ➌ 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.
