Pros: More Amps, Display
Cons: Fan - just how noisy is it?
Which is the more reliable unit, please?
since there is no overflow of replies I'll say a few words.
Personally, I would oversize the controller in case I'd want to add more panels later.
With regards to the Outback it would mean going for the FlexMax 80, and with regards to the MS it would mean going for the 60, for about 50 and 100 bucks more, respectively. Not so much more money in the grand scheme of things.
If you would end up adding more panels later, a bigger controller now might save you from buying
another controller later. If you definitely will not add capacity, then why bother.
You can buy a display for the MS for about 80 bucks.
MS are designed and engineered in USA but made in Taiwan
. If it matters. Good quality stuff have come out of Taiwan
for decades, and I reckon MS have QC in place.
Outbacks are all American.
Some folks here have recommendef this vendor in the USA: (I have no connection with them)
Charge controllers from Wholesale Solar
You can also do some comparisons and research
at their web site.
If you are in the USA I would give them a call. They should be very helpful and knowledgeable.
A person here on the forum I have become to respect very much for his knowledge on solar
(and many other subjects) is Noelex77, you might want to try to pm him for a comment.
You could also try a Google
search, just type in "Cruisersforum Outback MPPT" for example and you should get some info.
As to your question "which is more reliable" I think you won't get a definite answer on any forum. Instead, a lot of opinions. My opinion based on what I have read is that the MS might be a bit more reliable. But I have never owned one. So that's all it is, just an opinion.
If I was you I'd think really hard about the tiniest detail you want from a controller and then get the one that ticks most of the boxes. Both of these are very, very good.
