BUT,unless it says otherwise, its still a 208volt system, and really likes 208volt.
If you get some crazy voltages, the UPS will handle it. But DO NOT hookup up a 208volt UPS to your home's 240volt power.
If you do, the UPS will trim the voltage from 240+ down to 208volt. If its doing this all the time, the batteries, system and everything will fail prematurely.
Then what do I do for home systems that need a 5000va and have 240volt?
Either a 230volt system OR a step down transformer from 240v to 224v.
But the best idea is to stay away from the high voltage and get two 3000va systems... its cheaper
