That's a pretty sweet setup, but look at all that real estate being towed! Lots of room for more panels there. A good Anderson connector between the trailer and "home" and you're golden...more golden.
Nice job !
Though I bet it would be nice to have some panel racks that you can tilt when you are stationary - at least if you are every up in the north on these short days of winter.
But guessing you don't have that issue .

You have a good old Heart Interface inverter !
