[RE-wrenches] Mounting Enphase when using S-5-PV Clamps

[Bill Brooks]

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.

Mornin,

 

I'm looking at mounting an Enphase M190 system on a standing seam metal roof
and was considering using the S-5-PV clamps (as opposed to just the S-5's
and L-feet), which do not use any mounting rails.  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
