The Somfy RU28 Li-ion Charger (9020812) is a dedicated charging solution for Somfy’s Roll Up 28 and Sonesse 30 Li-ion (v1) motors, ensuring safe and efficient recharging of integrated lithium-ion batteries. This UK plug-in charger is specifically designed for older (v1) Somfy Li-ion motors, making it an essential accessory for maintaining the performance and longevity of your motorised blinds.
With a 1.8-metre supply cable, the charger provides ample reach for most installations. If additional length is required, a compatible 2.4m extension cable is available separately. The charger is easy to use—simply connect it to the charging port on your motor and plug it into a standard mains socket. An LED indicator (on most motors) will show charging status.
The RU28 Li-ion Charger is compatible only with v1 motors that feature two cables at the motor head (one antenna and one charging cable). For v2 motors with a single antenna cable and a built-in charging port, you need the v2 charger. This charger is not suitable for use with NiMH battery packs or other motor types.
Ideal for both home and commercial settings, the RU28 Li-ion Charger ensures your Somfy motorised blinds remain powered and ready for use, with a typical charge lasting up to 11 months of average operation.
We have a range of chargers and power supplies for electric window blinds. We have plug in chargers, solar panels which trickle charge and also plug in power supplies.
