Benn,
If it were me, I would mount rails on the S-5! Clamps so that you can mount the micro-inverters on the rails. It is not good to mount the inverters on the module frames. Although some modules may be able to physically handle it, as you noted, you will probably void the warranty. The weight tests for ac modules are substantial and a typical module has not been evaluated for that dead load weight test. Put the inverters on the rails they were designed for or use a string inverter. Bill.

No rails means no where to properly mount the M190's!?! It was suggested to mount the M190's to each module frame using a fashioned L-bracket, makes sense, but this would require drilling holes in the module frame, and wouldn't that void the module warranty? Also, am i the only one who is wondering if hanging a 4.4 pound inverter off of the module frame will potentially cause some sagging/deformation of the frame over the life of the system? Is this how those "andalay" modules support their inverters? thanks, benn DayStar Renewable Energy Inc. b...@daystarsolar.ca 780-906-7807 HAVE A SUNNY DAY
