I am an electrician so I am aware of ampacity and wire sizing however, I don't understand how solar panels move enough current through such small gauge wire. Apparently, each panel has just big enough wire for the current it needs to carry. By the time the system gets to the inverter the wire would need to be huge (see the input terminals on any decent sized inverter). For the record I will be setting up a system to charge my 2013 Leaf during the 8.5 hours it sits dormant at work. Sounds simple enough but it only charges quickly at 240 VAC and needs at least 6KW. The equipment alone will run near $2k so it's more of a prove it can be done thing. The payback would be forever or worse considering most of the local charging stations are free!
