AC220V backup power from 12V battery with mains failure

It will mainly depend on the number of opening and closing cycles that will be done over the period... Honestly, look at your oldest motorization that I had in hand was over 30 years old and already had an entry for a backup battery... 12 or 24V. And you freed yourself from everything else

If you are talking about a gate motor, I have a system that has been running on a 24V 2Ah battery (car remote control) with wireless vacuum cleaner charger for over 2 years. the load consumes 1 W max during the necessary time, then 0 the rest of the time

What I meant is that the garage door motorization in Remundo is probably designed to integrate a rescue battery
