[QUOTE="Ridge Runner, post: 513238, member: 3775"] Yes you are, If you hook up 4 X 140w panel in series that will give you 560w in total and around the 90v going in to the Controller which it will convert down to suit a 12v system, But because they are in series even on a bad day SAY it is only putting out 45v that's still 45v going in to the controller So it will still put out well over 14v in to the Batteries, I told the Solar Store exactly what I wanted to do and they Told me that the 100/20 Victron and 4 X 140w panels would be the right combination because even on Cloudy days you always get the maximum Input Voltage to the Batteries and that is the exact system They worked out for me because Not only do I want mine for Camping but I want it to work as an Off Grid system to, And their Design Tech Is the smartest Guy I have ever come across when it comes to Solar power His Brain spits out these Numbers faster than I can tell him what I want and before I have the next question ready he has already told me the Answer, Your 100/20 will easily handle 4 140w panels and 4 X 150w will put it right on the edge, Then you can go to 6 panels by splitting them in to 2 banks of 3, etc, The secrete is in how you configure the way the panels go in to the Controller, So Try and keep the panels around 140w each and get 4 of them just to keep it simple, 4 X 150w would be peaking the system when they are all in One String, OK Hope that helps.
