Frequently asked questions

Which roller shutter does the AM45 battery-solar motor fit?

Calculated with a 60 mm octagonal shaft (winding radius approx. 5 cm), the AM45 battery-solar motor handles these roller shutters depending on torque:

Torque	max. curtain weight	approx. shutter area (PVC, 4.5 kg/m²)
10 Nm	up to approx. 13 kg	up to approx. 2.8 m²
20 Nm	up to approx. 27 kg	up to approx. 6 m²

Guide values based on the formula torque = curtain weight × 9.81 × winding radius × 1.5 (reserve for friction). Aluminium, wooden or security curtains are heavier – then choose the next size up. If in doubt, send us width, height and material and we will size the motor.

Do I need a power cable?

No. The battery is charged via the solar panel; no electrical installation is required.

How long does the battery last?

According to the manufacturer, around 6 months with one up and down cycle per day without recharging.

Can I control the motor via app?

Yes, with the Zigbee version via a suitable gateway. The standard version is operated via radio remote control.
