I'm planning on running 2 Bluetti AC300's together in split phase to a transfer switch. The transfer switch will power lights/outlets throughout the my house all of which will be 110v other than my AC. My question is, if I'm not running my AC and only pulling small amounts of wattage (0-2500W) do both inverters run all the time or does only one have to run and the other turns on when it's needed? My guess is if I'm pulling more than what 1 can handle (3000 W) I'd have to manually turn the other AC300 on or I'll set an error code. Any info is greatly appreciated
