This battery-powered roller shade motor kit is designed for electric roller blinds, shades, and other window treatments. It allows for sunrise/sunset automation and includes a wireless blind motor, drive wheels for 38mm tubes, a remote control, an 8.4V charging adapter, and mounting brackets. The kit is compatible with solar charging for continuous power. Installation is straightforward: unclip your blind, remove the chain drive, measure the shade tube's inner and outer diameters to select the correct motor size and drive parts, insert the motor, and set up your controls. This motor can pull shades up to 4kg. Please note that different diameters of Rollerhouse tubes are available and must be ordered separately.
