    from £395

    The Sunsquare PSU1 24V 7A Battery Back-Up Panel will operate our Aero Electric range of skylights should you ever lose mains power. It’s a convenient way of enjoying 24/7 functionality of your Sunsquare skylight’s opening features, along with any other automated controls you purchase such as our rain sensor or weather pack.


    It’s extremely unobtrusive during day-to-day operation. The Back-Up Panel has been cleverly engineered to intelligently charge the built-in battery from the normal 230V AC mains supply, only switching to ‘Emergency Mode’ in the event of mains power loss. Put simply, it’s always there when you need it and is yet another way we provide our clients with 100% peace of mind.

    The back-up panel is capable of completing an average of 35 operating cycles (open/close) while running via ‘Emergency Mode’, powered solely by the efficiency battery. This should be enough to guard against even the most serious of mains power failures.


    And once the normal 230V AC mains power returns, the PSU1 panel will automatically revert to normal operation, allowing the battery to be recharged in full. In this day and age, you shouldn’t have to worry about power loss and our state-of-the-art technology allows our clients to enjoy our products day in, day out.
