I'm building a solar powered shop with battery storage. While some of my motors will require 120/240 volts from an inverter, the stepping motors can be powered directly from the batteries.
Does anyone know of a computer that will run LinuxCNC, that can be powered directly from batteries and bootable from micro SD card? If I convert to 110 and run it through a power supply to get back down to 12 and 5 volts, I lose power during both conversions. An SD card would draw less energy than a hard drive.
While I know laptops run off batteries, they're usually an odd voltage, not a multiple of 12.
One of my spindles is powered by a VFD so I hope there's a DC version of it as well.
