Hello guys. I'm thinking this is going to be a dumb question for educated electronic people. I live in a 12 volt house. I wired it myself. Panels through PV controller to batteries. Batteries to house fusebox. Fusebox to lights, stereo etcetera. I want to add extra panels to the system. They will only fit on the roof of my house. Not on my battery shed. Can I wire these panels, through a PV controller, into the 12v wires that enter the house. This would mean as I understand it. I will be requesting amps to flow to my house on request from appliances. And at the same time, sending charge back to the batteries along the same wiring. Can I do this.???
