Background.
Existing customer, the one with the German built kit home. He has a detached double garage. 2x electric garage door openers that can be opened inside or with a key switch outside.
There is no other doors into the garage.
There is a manual way to open the doors but only from the inside.
Last year during the storms, they lost power for 7 days. They could not get their car out of the garage to go anywhere.
What he has asked for is some back up power supply that will allow him to open the doors from the outside in the event of a powercut.
It would need to automatically switch over to the back up when main power drops.
He has also asked if it can be portable. Ie, once the door was opened, could he take the unit into the house and use it there for powering laptop, phone chargers etc.
(This could be a separate unit if it becomes too tricky to make it portable)
Each door opener is rated at 170W, and the garage board also powers lights and general sockets.
What sort of time would they last for? A couple of hours maybe? Enough time to open the door and get the car out?
