I was curious if anyone had slapped some solar panels on their roof and swapped out a PSU for a DC based one. And or where to find such a thing. It seems highly inefficient to go from DC solar panels -> AC plug, -> DC battery in the UPS, -> AC to the PSU.
Plenty of enterprise equipment has 48V DC power supplies.
My work setup is Mains -> Rectifier shelf -> DC PSUs/Devices
Batteries are hooked into rectifier //
