Discover and Sol-Ark pair well together in closed loop. Minimal fuss with

their AIO.

Large array is fine. If I remember correctly, Dankoff pumps are fairly low

Here's a different take. Just food for thought and not necessarily a
suggestion. Those 1st or 2nd Gen 12V systems were/are for me the most
reliable and trouble free systems. I'd install one and never hear back from
my customer for a decade or more. I regularly see "rats nest" wired

Am I missing something? Schneider has come up with a solution to the
discontinued SCP by using a tablet connected to the Insight's ethernet
port. In doing so, by utilizing that port it seems there is no longer a way
to make a wired connection to the internet.
