    I mean, the other option is you’re pulling things out of your ass like every other armchair expert on the internet.

    There are several different possible phases for 120 volt

    Like…no. You get 240v 2p incoming with a split bar. 120v is 120v is 120v. Maybe you’re dealing with 3 phase power but a residential building is not. And I have no idea why you’d have an inverter that outputs 3 phase power in a residential building.

      This is a nice little experiment to show you what happens when you try to parallel two inverters that are not synchronized. Just because the voltage matches does not mean they are in the same phase or synced up with their sine waves. You can also just look at the manual for any dedicated off-grid only solar inverter and they will make it very clear that you are not supposed to hook the output up to the mains panel and doing so will void your warranty and damage the unit. But I’m sure that those inverter manufacturers have no idea what they’re talking about /s
