hello, today I received the charge controller 30A, I have 11 solar panels 50Watts, then hooked 6 solar panels to charge controller that is connected to 3 car batteries 12v used, the panels were connected in parallel to get 12V the remaining 5 panels stayed connected in series to the grid tie inverter, since you need at least a 75v to turn. the grid tie inverter is
German, is still 1 year warranty and is fully automatic.
