Mine has a cylindrical fan housing about 2ft tall that blows directly into a 14" square MIEV 11 air filter in the roof vent. Mostly for wildfire season in the Summer.
My current plan is to raise it up another 3 ½" on a 65" wide frame. The roof vent spacing works out for four solar panels grouped one and three. With appropriate flapper valves, one mode would blow air underneath for air cooling for the best performance you can get with panels laid flat.
For the microgrid, I'd thought the $1800 Ecoflow Delta, but reviews suggest it's more for tailgate parties than daily charge/discharge. So now I'm 'lurking' about a $600 controller and I don't know what batteries.
