[RE-wrenches] Strange Question: 1-Panel System

[Jerry Shafer]

Jason,
Just go with the enphase and just the EMU  (Enlighten Monitor) not the
combiner box and let it fly, easy to add later on if so desired, I would
stay away from these off brand products, Ya I know enphase has its issues
too, BTW do you need a dedicated monitor, I have used one that i moved from
site to site instead, it was a little bit of a pain but helped
Fun times
