Re: Want to move to all 208V for server racks

There's also a telco oriented 48V inverter rack system thats escaping my mind at the moment. It can be setup with A/B 48V strings, and you plug in inverter modules up to IIRC around 8kW. Not parallel capable between racks AFAIK.
48V (and some more when batteries are full) are slightly below the limit of non harmfull voltage.
Thus you have a voltage with less power loss at short transports and a secure voltage. (creating a short is still not a great idea).
Kind regards, Ingo Flaschberger
