Connecting solar controller to inverter or converter feeds

This is the was I am getting ready to do mine as well. Electrically it isn't that much different than connecting to the battery. Your connection point is just at a different end of a piece of cable and in my case the inverter cable is fused to 250 amps. The most I have ever seen on the inverter is 160 amps and I am installing a 30 amp controller that will occasionally see 30 amps.
