Smk, you can set your Vabs and a time for it, but AFAIK you can't keep the controller in MPPT except when it is in Bulk.
This is true! And should be expected. Morningstar explains it right in the manual. afaik ALL MPPT drop out of MPPT when it is no longer necessary to provide what the battery needs.
Example: If the battery will only accept 50 watts there is no need for the controller to extract 350 watts. There is no way to stay in MPPT. Where would the power go?
It would be like wondering why your 40 amp charger is not extracting the full rated 900 watts from the plug as the battery has tapered to accepting 5 amps.
Put a load on it and they go back to max power or MPPT mode.
