Sorry if this is nonsense, but your existing Radian is your "AC grid source," It can act as the paralleling. AC coupling source. I did this about 20 to 30 years ago, using FX inverters, not Radians, to power a large motor. Can your Radian Mate 3 run in grid zero? Or if not, one inverter runs all the time as a grid source ( grid forming) the second inverter (grid following) runs in Grid-Zero mode, with "off-set" set at 30 Amps. If the load is less than 30 amps, the grid-following inverter carries the load. (The grid-forming inverter supplies the grid signal, and the following inverter carries the load.) When your load exceeds 30 amps, the extra current comes from the grid-forming inverter. The Radian can pass up to 50 or 60 amps from the forming inverter. You can get 50 to 60 amps to the load when you add the forming and following inverters. Errors: this will double your parasitic load, I have not done this so beware. This is not the answer for V2H; other inverters can work in this combination but
