Alan, watch the Generac installation video(s) on the 'Tube...the weight isn't a factor because each of the up to six batteries is installed one at a time and that doesn't happen until the cabinet is placed and secured. 
If I went that route, it would have been two battery setups (either two Tesla PowerWalls or two Generac battery setups fully loaded) to cover our backup needs. BTW, relative to the transfer switch, the Generac auto transfer switch used with their solar setup is "very similar" to the excellent whole house auto transfer switch that has been part of generator installations for some time now. It can even support both solar/battery and generator for those folks out there that want a power company connection but otherwise want/need to be "off grid" for longer periods of time during an outage.

The most expensive tool is the one you buy "cheaply" and often...
