In the datasheet you can see parallel operation is not supported yet, but it will be with future hardware revisions.
Although I am happy it’s finally here, my initial thoughts are that for a product that’s been this long in development i expected a littebit more. The ISC is indeed too low for modern panels, and although the max string voltage of 600V is a step in the right direction, this is a voltage expected from a monophase inverter, not a 3-phase, where 1000V is the norm.
