Flexible Metal Conduit to Protect Inverter Wires

I'm installing a flexible metal conduit called Greenfield Flex. This was suggested by my friend Ben. It turned out to be very easy to work with. It's thin aluminum and could be cut with just a hacksaw.

This is part of my larger off-grid solar project. I'm working to decrease my energy bills and have a back-up plan for grid black-outs.

The conduit connection are going from my SMA Sunny Island inverters, to my 6x6 wire-way. This metal wire-way has some pre-punched knockouts, but I still needed to make some. I made 2" DIA holes for nominal 1.5" conduit. This larger conduit will be for the thick battery cables.

I punched the holes in the wire-way using a hydraulic punk kit from amazon. Link below. It worked surprisingly well.

If I did this again I would buy 6x6 wire-way without any punched holes. I didn't know any better when I bought this, but the wire-way comes with or without knockouts. It could have looked cleaner if I made all the holes myself. O-well, next time.
