If you do invert, don't forget the cooling budget. Inverters run HOT!

They can provide scalable inverters for 120 and 208/240. Modular N+1 setups and very flexible.. We have a large 200amp 120vac setup from them. I'd recommend letting your electrician build a parallel setup instead of relying on their modules, however...

The most recent thread on this list was about -48V DC modems but in our case I am rather looking into inverting on the order of 4 kW per rackfrom thesupplied DC into AC equipment. And yes, that's not the mostefficientuse of power, we know it already ;-) . Does anyone operate devices like this that are capable of 2...4 kW power conversion and do you have recommendations, good or bad experience to share? Please reply direct to me and indicate if it's OK to useyour answerin a summary e-mail back to the list.
