I am looking to put in a FlexBoss21 for our house. We have seven of the Mitsubishi Mr. Slim AC units. These each have an inverter that takes the 240 to three phase variable voltage variable frequency. Anyone have practical experience with this? The question being can you feed the inverter output of the FlexBoss21 to the inverter driven compressor in the Mr. Slim AC unit? Mr AI gives me both yes and know depending on how I ask the question.
