This afternoon, I took my battery bank apart piece by piece and made sure all my lugs were securely attached and that all nuts were tight. I then triple checked all the connections with the multimeter and got readings of 13 volts and change. I then checked all the fuses and they were fine.

I didn’t feel that I really did anything and I decided to just give up already and call Xantrex and see if they had any ideas about what could be wrong with the battery monitor.

I came in, turned the solar control monitor back on, then I turned to the battery monitor and in my best Samantha Carter voice, I screamed, “WHY WON’T YOU WORK?!”

At which point I noticed this:

I fixed it!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Now, I doubt it will be super useful in my first week or so off the grid while I figure out how exactly it works and get it calibrated, etc., but this is worthy of a victory dance!
