Yes, self consumption is pretty high at 200W. Thats 4.8kwh per day, so almost a 100Ah battery load. I didn't really have any critical loads on, like a desktop computer, so hard to tell, if the switching would have caused problems. The only sensitive thing was the digital display on the gas stove. Whenever we caused a power outage, during installation and testing, that display would blink and we had to reset the time. But it never blinked, when the automatic switching happened, so I guess the 10ms switching time seems to be accurate and not noticeable.
