Does anyone have practical experience with AC units that have an internal inverter? We have seven Mr. Slim units from Mitsubishi in the house, this is rather than central HVAC. These have an inverter with power factor correction, from the 240 volt input they produce variable voltage, variable frequency three phase power. They start at 24 Hz and 186 volt and ramp up to 480 volt and I think 60 Hz.
If you ask AI if you can use your FlexBoss21 to run your inverter A/C unit it comes up with a list of reasons this is a problem. If your next question is can you run your inverter based Mitsubishi AC from the FlexBos21 it only talks about load issues.
Has anyone done this or have first hand knowledge that it is supported?
