Excellent for what I have read.
Although I think you shorted some of the Morningstar MPPT 60 controller functionality.
The programming in MSView is very comprehensive to the minute and two decimals on the voltage.
Option to extend absorption as long as you like based on start voltage. Or for very low voltage float can be disabled.
Yes it has a programmable function to restart absorption if voltage sags for a time you can specify. And it accumulates. So if you set 15 minutes and use your microwave for 5 minutes 3 different times it will revert back to absorption.
Many accessories to provide other functions such as drive a relay to start your generator or cut power etc. Can send you an email if voltage sags. Multiple controllers can be linked and sync the programs. And more that I don't recall.
