It is true that if you insist on making the cutover from inverter derived AC to grid AC without an interruption, you will need some subtle circuitry that can automatically "glide" the inverter into synchrony with the grid before cutting over.
I don't know if Tesla, Bluetti, and EcoFlow devices do this, or just make a step-change in the phase and frequency of the output. That would be an interesting investigation, maybe Matthias Wander can do it?
- rocqua 4y agoFrom what I remember the main problem is code requirements around being able to go from 'isolated' back to being connected to the grid. If you are out of phase when the grid gets back, it gets damaging. So it is difficult to get an approved system that can do it.
