I just use Outback and Schneider because their systems have web portals
that I can monitor, troubleshoot, and advise on. I have never seen anything
decent monitor wise from Magnum. Until 5 years ago they did not have a
charge controller. If I am wrong about Magnum please post a link as I do
not want to post false information. Thx.
