[QUOTE="stuboy, post: 531452, member: 33489"] If your panels are facing the same direction and there is no shading, simply "seriesing" them up will solve all your problems. It used to be even worse with the SMA Sunny Boys as they had a 175v startup but once alive it would run on a much lower voltage, I never really understood that?! Off the top of my head I think your threshold is 120v on the inverter you have? The on off fix is that when you take the panels off line they are not on any load so float up to whatever their no load voltage is, when you crank the switch back over it sees the higher voltage and says ok that's enough I'll switch on now. If this was installed by a "professional" they did a s*** job! They clearly need to go back to school and take a basic course in maths;-) Hope you get it producing like it should :-) Cheers Stuart [/QUOTE]
