Hi,
So I just changed out a 10 year old Morningstar 45 MPPT to Victron 150/70 VeCan.
Problem is that even if I get 35v on the PV side the controller charges at max 15w normally more like 6w.
It's the same connections I had on the Morningstar and it had no issues pulling in 300w in the same conditions. (Connected are 8x250-270w 24v panels in parallel). Battery is a 1000A 12v consisting of 6x2V flooded cells.
Any suggestions what to do to get the Victron to work as expected?
I have a 100/50 Victron also and that is working fine but with that one I have 4x410w panels in two pairs so the voltage is 65-70v.
I can try swapping the 8 connected solar panels to 4 pairs of 2 to push the voltage up to 65-70v also, but it will require quite some work to do, so I'd first like to hear any suggestions on what might be wrong first...
Can't upload pictures to this post for some reason, will try to add in first comment.
