Install new Rogue MPT-3048
I just posted my review of the new controller from Rogue on FB, and since all the design/support/ideas for my system came from here, I thought I would copy my high-level review. I do plan to post pic...

Let me add a little more detail to my test. I was looking for a way to "stress" my setup- since the PV/controller won't do much if the batteries are already charged. Originally I was only going to install one 235W, but didn't want to get into tilting, so added a second one. The company I work for manufactures these, which is partly why I chose this setup- to bad they don't give employee deals.....
Anyway, connecting the coffee maker through the inverter pulls about 115A for the first 8 seconds or so, then drops to 75-80A while the rest of the cup. During the initial 8s (while drawing 115A), the Rogue was putting out the 30A. I should note that the battery voltage drops pretty quickly under this load, and stabilizes around 11.6V. The Inverter isn't to happy at this level, and complains with an error of low voltage, but still works. I was worried that 2 T105's isn't enough capacity for this, and will probably upgrade to 4 next year.
Thought's on if I'm doing harm to the inverter under this condition?
