[RE-wrenches] Micro inverters not on the roof.

[Larry Crutcher, Starlight Solar Power Systems]

William,
If your Vmp drop is under 2% (my design goal for maximum acceptable loss) I can't see any reason why not.

Friends:
 
I am reworking an existing off-grid system to become a grid-tie with micro-inverters.  With your help, we have already determined that the M-190 inverters will work and we have acquired the 9 of them we need.
 
Since the installation was completed in 1996, the home owner has installed a shade cover over a skylight.  Some of the supporting structure is preventing us from getting under the modules to install the M-190s.  Each module was fed to the equipment cabinet since the combiner was located there.  I have decided it will be much easier to install the M-190s in the equipment cabinet.  We have everything we need there:  The individual PV leads (in 10AWG), the breaker panel and room to mount the inverters.  Can any of you see any reason why the M-190s can’t be installed no on the roof?
 
Thanks in advance,
 
William
