When batteries are depletd and ther's not enough production or for some reason the demand exceed the production + batteries availability the inverter goes off and switcher automatically turn into grid, and when inverter provide again energy it will switch back autmatically?
There's a point here. Is not possible that it starts to loop like that: switch to grid because the load is too high, inverter recover a normal state because there's not load connected anymore, switch to inverter, but the load is too high, so inverter cut off again and switcher switch to grid and so on again and again in loop?
