Glitch: Yeah, 100A @ 24V is a lot (I hope so), but I'm charging 6*banks 155ahr batts, but I think I will only get 100A+ peak at a few hours of the day. I have seen 124A read on the 150A shunt when I plugged it all up one time in the middle of the day - and then the controllers settled down...
Thala Dan: The 'rust' nut is actually a lug. But you're right I think I have neglected to keep them clean. However, I have undone nuts/connections that have had corrosion ont he outside, but when undone it's shiny inside.
You're correct though and a good reminder to me. I'll undo them tomorrow after dusk and check them. Sometimes one gets focused too much on the big things and maybe it's the little things that are cuasing the problems.
I'll report back and let you know what I find.
Your 70A shunt looks great, but I still find it hard to understand that those thin strips of metal are meant to allow a full 70A-100A of current @ 24V through them.
So if 80A is input - what A comes out?
