Steps: Connect solar system in this order: 1.battery--> 2. PV arrayload--> 3.DC load, and disconnect solar system in the reverse order >3. >2. >1.

Battery must be connected first ! Never connect soalr panel array to controller Without/Before connect battery.

DO NOT connect any inverter/wind/Alternator or Charger into the charge controller directly ! You should connect with battery and add fuse .

The fuse should be installed as close to battery as possible，the suggested distance is about 150mm
