¿Qué potencia en W/h se puede producir con la siguiente configuración a través de las tomas EcoFlow Delta 3 de 1536 Wh?

I would like to know the amount of energy in watts (Wh) that I can produce with the following configuration: a PowerStream800 with two 400W panels (each connected to its respective MPPT), without the PowerStream feeding energy back into the house; and connected to a Delta 3 1536Wh battery, which in turn has its own 400W solar panel connected. How would this system perform when the Delta 3’s battery is fully charged, and the Delta 3’s AC outlet draws a load of 950W? In other words, I want to confirm if, when the battery is fully charged, the energy that can be drawn from the AC outlet would be approximately 1200W.
