Rogue MPPT, 490W and charging mysteries
Now that we were finally all in one place - me, Rogue 3048 and my rig - it was time to have some fun. 1)Battery: old starter, tested beyond dead, plates above the water. No wonder, 8 months in Mex...

The controller won't transition to float based on battery current if it's unable to hold the battery voltage at the absorb setpoint (as appears to be the case with that old battery). It should transition when the timer expires, though, regardless of current...
...The controller may also attempt to see if there's a new MPP during absorb or float if circumstances cause it to bump up against the last measured MPP, but I don't think that's what you're seeing.
Does this mean that it will be doing MPP step-up every 1-2 minutes after it had transitioned into ABS 14.4 and is staying in ABS at 14.4? Is it sweeping constantly because is trying to raise the voltage to 14.6 while already in ABS?
This all is only for me to understand the algorithm better. It doesn't do any of those odd things with a battery in good condition.
