I’ll bet. I had to bend 400 MCM Cu in a transfer switch.Getting that 300 MCM Cu cable to make the turn into the 225A breaker was a real challenge!
My bend was a little wider than yours.

Not sure I understand, why does a compost need a heater? Every one I've ever built had an internal temp of 160+ . . . .So how is the crypto mining going? I thought about adding a crypto mining rig as a dump load on sunny days. I decided instead that I'll build a motorized compost tumbler heated with a heat gun on a wifi timer.
I can't speak for the OP of this thread, but on our pole barn, and on my similar pitch metal roof home I used S-5 Versa brackets to attach to the metal roof Then the rail of your choice.I have a pole barn with a metal roof very similar to yours and I'm looking for mounting brackets. Which ones did you use?
Thank you for the feedback. I'm going to read up on all of those options to help me make my decision.I can't speak for the OP of this thread, but on our pole barn, and on my similar pitch metal roof home I used S-5 Versa brackets to attach to the metal roof Then the rail of your choice.
I've used Unistrut (from bigger box stores - I don't recommend due to scarcity of panel clamps etc), low cost Prosolar rails and clamps, and most recently the very low cost Signature Solar Mini Rails.
S-5 makes a large assortments of metal roof hardware mounts. Their VersaBracket is water tight and the most economical.Thank you for the feedback. I'm going to read up on all of those options to help me make my decision.
The next day the POCO came out and killed the power to the house, and moved the cables from the pole into the new meter base and energized the new panel and left. It then took me about 3 hours to mount the transfer switch and run new 3/0 Cu to the sub-panels in the house. Bending 3/0 Cu is no fun at all, although it was not nearly as bad as the 300 MCM feeding the solar sub-panel.

Next I decided to pour a pad and make a "power room" where the service enters the house.

The roll of cable is a 24 strand fiber cable that I ran down to the shop building since I had ditch dug anyway.
20 kW Kubota generator installed and wired:

Last month I decided to ditch all the micro inverters and go 100% SMA SB string inverters. Doing all the ground mounted arrays was easy since I had easy access to the inverters, but the 56 panels on the roof were a different story.
I hauled a pallet up onto the roof, got it level, and the moved the top row of each array section onto it, and then shifted the remaining panels in each row, up one:

Inside the shop, I build a frame to hold all the inverters along with the 225A sub-panel. Here's a shot from when the shop roof arrays were still on micro inverters:

All PV wire going into the inverters are 10 AWG and the A/C output of the inverters going to the sub-panel is 6 AWG. The feeder wire from the solar sub-panel to the converted 400A shop meter base is 300 MCM Cu.
Output when the sun is out:

Quite possibly could be otherwise how is he going to use 300 kwhr per day?He is probably on his yacht off the coast of France enjoying some Wine and the scenery, all purchased from his mined Bitcoins. ?
