Outback flexmax is a very high end controller, the one big drawback for me on this one is programmer is a must to set many of the settings necessary. I picked the Midnight as no remote programmer is needed, its all on board. Every setting or thing to be monitored can be done from the front panel. Both of these controllers were designed by the same teams, both companies are started by Robin and boB Gudgel, they are also the founders of Trace Engineering.
I see the evolution of design over the years, the Midnight is the latest and best from the Gudgels, Arc Fault and Ground fault built in, no expensive ground fault breaker required as in the Outback. No need to use your phone to program, RJ-45 port for remote monitoring or programming built in , accessible from online,
Do get the built in display, its not elegant, just very practible, no whistles, bells, fancy display.....down to the brass tacks, you can get any data you need or set any variable from here, very valuable when things go to hell
The Midnight lineup is expanding, there are inverters in the chute right now that hopefully be available this year
Yes, they are expensive, but the reliability is not matched anywhere
In all honesty I do need to admit that I am a Midnight beta tester, but that does not bias my opinion of equiptment,
I have always liked the best of electronics, I have a stack of that legendary Bob Carver stereo gear, some over 20 years old and cant be beat no matter the cost, did a whole career in electronics/electrics from DC to 12 Ghz
