[RE-wrenches] Micro inverters not on the roof.
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 cid:679355323@23072013-1054 17395 Oak Rd.

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

Re: [RE-wrenches] Micro inverters not on the roof.
I did something similar for my lab at the community college I teach at. Long story short, the lab used modules mounted outside on an awning and all the inverters (string, off-grid and micro) were inside so hookup could be done during poor weather or evening. Worked out nice.
