I'm using a 150/85 and set 13.85V Bulk with a 6hr fixed absorb time as I often get heavy cloud during the day, and a tail current set to 14A.
On bright full sun days the mppt goes to float very early like at 36A tail.
On dull days, it behaves its self.
I also have a 100/50 that is set up exactly the same settings.
I usually run it together with the 100/50 over VE smart network where they work well until I get a full sunny day and the 150/85 takes us to Float way to early before reaching the tail current limit!
When I turn off the 150/85 and run the 100/50, it does what I want and cuts off when tail reaches 14A.
Why is my 150/85 going to float early??
