[RE-wrenches] Off Grid Optimizers

[drake.chamberlin at redwoodalliance.org]

After doing research, it seems that the optimizers won't do what is
needed for the shading and orientation issues. The modules will be on
the east and west pitches of the roof. 

There is an existing array with a Midnite Solar Classic. There are 4
sub-arrays of 3 modules each , all facing due south  that act
independently. 

The new sub-array has more shading and orientation issues. We may need
to cut more trees, but would rather not. 

Although it seems radical for an off grid system., I'm considering
using microinverters, AC coupled to a Radian. Is this idea totally
crazy?

Thank you,

Drake

 Probably for shading! I cut the trees down to avoid all shading
offgrid.
