Hi my all in one takes 5 to 10 seconds to switch over from the battery to the mains when it comes back and I have not had any answers from give help. I thought it would have been the 20 milliseconds the same as it switches over to battery with no problem.

TonyHR9 That is probably correct - they system will not cut over right away - it waits for a while to ensure that the grid is stable before moving back to the grid
TonyHR9 Oh, and another thing - I don't think you'll get the 20 milliseconds cutover to backup if the battery is full and solar is generating more power than the house needs (and the AIO is over 80%(?) ) - it will need time to switch off the inverter before cutting over (assuming you do have solar panels that is) as it needs time to switch the inverter off to protect the system - at least that what happens to me - I'll be giving it a try in the winter when that will not be a "problem" 😆
