[RE-wrenches] Tech Support Issues with Sensata

[Bradley Bassett]

Just so you know, AEE Solar still has a bunch of Magnum panels and
controls, no inverters, no support though. At least until they find someone
to take it all. Keep an eye out for other close out stuff too. But, yes
they are still going and working on getting better.
