I have need of a VFD to provide three phase 230v off of single phase 230v. The load will be in the range of 5-7 HP, however, from my experience with the A-B Powerflex series they get derated by 50-65% if run off single phase, depending on model so that's why I put 10HP in the title. I am shopping for one that will power this load and when they get that big, they don't have a simple single phase rating published any more so I am wondering if those that have experience in this area can tell me what the derating is likely to be. The ones I have come across are Saftronics, ABB, Hitachi and there are more, I am not picky. It is a hermetic scroll freon compressor.
