Hello,
I have a Victron Multiplus II 48 5000/70-50A and Victron Bluesolar MPPT 150/70 connected to a 20 kWh lithium battery system (offgrid).
Currently I have 12 x 315 Watt Longi panels in 4 strings of 3 panels. I can get the same panels still so I wanted to add 3 more panels.
Panels are 40,6 VOC and 9.94A.
According to my calculations I could add another string, I will stay below the 150V (which will still be the same as with 4 strings, only the Ampere part will be higher if I am correct).
Is my assumption correct that I can safely add the new string?
