Hello,
I have the SCC115110512 ( 150/100 ve can) mmpt.
I have a 48V system. The mppt wit 2 panels in serie works ( +- 65 volts) , but with 3 panels ( 107 volts) it doesn't work.
If I google this mppt it's rated for a 12/24 volts system, but in the setings you can choose 48V. 
They sold me this unit 
as for 12/24/36/48 volts. I had contact with a repair centrum from Victron, and they said it should work on 48 volts. I received a new unit, same problem.
What is going on?
Ps. I'm Running a 3f 5000VA multiplus ESS systeem. My other mppt's are working fine.
I hope someone can help me out here.
My guess is this mppt is not capable for a 48 V system, but Victron is not believing me. I think the SCC115110511 is the one I need.
Has someone the specs of the SCC115110512?
Thanks Bjorn
