Red,
During this particular run the Tracer never went out of mppt mode, nor bulk charge. The bank was in the high 90's soc, by the end, but was still able to accept the lower (evening hours) amps from the controller. But yes, you're right... I will need to adjust the boost time; but to whatever is appropriate for any given situation, it appears.
My understanding is, once battery acceptance drops below controller output, the controller will drop out of mppt/bulk mode, and go pwm/boost mode. At that time, any extra amps will simply 'circulate' back thru the panels, and amps to the bank will taper. Knowing how long it takes to top up my bank (and the impending weather) should come in handy when choosing a time frame for boost.
I still have the issue of getting to true full, though. Selecting '100% soc' determines when charging stops, and it's getting to that too early. And I doubt going into boost for a while would change that? Perhaps there are other factors that can be programmed in for determining 'full'? I know it gives me another selection choice, but I'm at a loss as to what to do with it?
Thanks for the video links... hopefully I'll find an answer to my question there.
