My solar setup consists of 5 solar panels and 5 separate MPPT controllers: Two 315W panels each with a BlueSolar MPPT 100/30; and three 140W panels each with a BlueSolar MPPT 75/15.
They were installed 9 months ago, all with default settings. During the summer months I had plenty of charging and power. Now in the winter I feel my batteries (820ah wet-cell bank) are not charging fully, and likely need an equalization charge. I would like to set up the automatic equalization - what is the best way to configure 5 separate controllers for this. Do I configure each one individually or is there a way to make one controller the Master and the rest slaves?
The two 100/30 controllers seem to switch together as do the three 75/15's. But the 100/30's switch to FLOAT earlier than the 75/15's. i dont want them to step on each other.
