Your remodel is beautiful. I really like the built in cabinets and the custom look. I had a shack like that before my last move and I am slowly getting back to where I started. It makes such a difference when you have dedicated, purposefully designed space. Great job.
I think you are asking about the power supply and battery back-up.
I have a Astron RM-60 Power Supply running into a West Mountain Power Gate that charges my gel-cel battery and feeds power to the West Mountain 4012 Rig Runner with Anderson power poles. The PWRgate charges the battery with power from the power supply and automatically switches to battery back-up if the power goes out. Above that is a Andrews Ground bar for grounding the equipment. Also the blue box above the power supply is a solar panel charge controller . Still hooking up equipment and trying not to make a rats nest of all the wires that can be hard as we all now !! Hope that answers you ?'s 73'S
No i have a solar panel but don't have it hooked up yet. Still looking for good place outside to mount them.
Would also like too have a large bank of batteries and some more panels . Maybe some day!! when i win the lottery .
