This is our second full day with zero solar though our panels are bathed in light. I have not touched my wiring. Nothing has changed yet two days ago we were getting great charging from them and now yesterday and today absolutely nothing.
Help?

Since issues in VRM solar is now completely off line
Hi @Allswell
All your data suggests that the mppt has lost contact with the batteries. The 0.00V min achieved means it isn't even reading Vbat. Maybe a blown fuse, broken wire, etc. It's going through the charge states just trying to drive current into it's own terminals.
It's not VRM.
Looks as if your batteries are too full to accept more charge. This is a 24V system, or am I missing something?
For a 24V system, the voltage is very high, will lead to battery damage.
And now it’s saying it’s in Float but it literally hasn’t done anything all day and yesterday.
Why is this happening after I did nothing at all and all connections are the same as they were this entire time?
Just doesn’t work anymore
Please confirm system voltage and post a screen shot of the MPPT settings.
So @JohnC it turned out it was the 40a fuse on the pos+ line out of the MPPT to the main pos+ on the bank. So I replaced it and it worked as it should. Then a few hours later that fuse went as well.
Solar is offline again.
I cannot figure out what’s wrong here!
