We live in an existing early 1990's built two-story home in the Austin, TX area and we are in the process of replacing 23 cellular window shades with 23 motorized 12-volt roller shades from Graber (the Virtual Cord product). These shades can either be battery powered (8 or 16 Lithium Ion AA which are replaced every 6 to 12 months per shade) or a plug-in (12 volt transformer option.
We have 11 windows on first story and 11 windows on second story. Our windows are simple recessed in drywall, nothing fancy. The bottom sills are made of quartz (leftover material from countertop project). No wood casing. Each window is between 3 and 4" deep. The new motorized shades will be outside mount and sit right on top of the window box. Most every window location has an outlet near / under it.
I would love to find a way to have the majority of our new window shades operate as "plug-in" instead of battery operated.
Any ideas? Suggestions for how to bring power to each window for plug-in operation.
Note: The Single Motor Transformer (pictured below) for the Z-wave shades is 4" (10.2 cm) wide x 2" (5.1cm) deep (not including the plug) and 1 1/2" (3.9 cm) tall. 120V AC to 12V DC. 1.6 amps. The end that plugs into the shade is a micro-USB cable. It is specially design and is not USB standard, so we don't recommend using any other USB cable or extension. The lead is 72" long and it comes with a 96" extension cable included. You can chain a maximum of 2 extension cables if needed (22ft total length).
