What make is it and where did you purchase this from?

(Yes, I am still around)

Right at solar noon, I sometimes get that much on a nice days in late June.

My 2619 doesn't have a ton of additional room up front, and adding another panel into the current string would be pushing a lot of voltage (110-120V) into the "150 volt" MPPT. The short period of time near solar noon when converted panel output exceeds the maximum 30A output rating rating on my "13.6 volt" MPPT would also be greatly extended.

I have purchased a 200 watt panel for the rear shell, and a second MPPT unit to run that panel as a separate string. This is a solid-framed panel, too heavy for my front shell but probably OK on the rear (where I still have have several turns of adjustment left on the torsion bar ends.) I actually expect nearly 200w in perfect conditions, the disconnected voltage was all the way up when I set it down on the driveway near 1 pm. I'm waiting on the MPPT from china, it should arrive in 10-30 more days.
