MS TS-60 MPPT Solar Controller Data

We're in boost for just a short time. It doesn't matter if controller is a couple of minutes longer in that mode.

YOU may be, but others don't necessarily use their system the same way you do. Using solar as a power source and not just a battery charger, the controller stays in MPPT a majority of the day.

Been reading your related thread and saw Marc's response - sure is nice to see him responding and clairifing many of the issues.

I did several different tests one running 10 to 15 minutes while the controller switched between operational modes (the unit allows looging of the operational modes as well as many other things not graphed earlier).

How about taking some measurements from your nice new controller and posting them?

During the above graphed tests my battery bank was 99% SOC which makes what your asking is a bit difficult to answer. With a 560watt PV array and a "small" 220amp/hr battery bank. I personally do not have any issues with getting it fully charged even when drawing 20 or 30amps for external loads. Most times in the late afternoon I notice 13.2 to 13.6 battery volts being displayed by the trimetic.

Look at the bettery voltage graph it stays a constant 14.5Vdc (or there about). I guess it was in either MPPT or ABS modes during the above graphed tests. Remember the displayed "Battery Current" is actually load current not the current the battery is receiving - for the above tests I did not log the Trimetric data which shows only the battery I/O current.
