Happy New Year All.
I have a CyberPower rack mountable UPS. It is a small business class 1500 W unit, model number OR1500LCDRTXL2U. Been unplugged for a while so not sure about the battery state. Here is a link to the CyberPower webpage for the unit. I have the rails for it, or you can purchase the feet to stand it up.

Easy porch pickup, but it is HEAVY. I can help get it into your vehicle.
