Somfy 9028922: Precision 15V 1A Li-ion Charger for Zigbee WireFree Motor Systems
The Somfy 9028922 is an optimized 15W power supply engineered for Somfy Zigbee WireFree Li-ion battery packs, providing a 15V DC, 1A fast charge. Its CC/CV algorithm ensures efficient and reliable power delivery while integrated multi-point protection features guarantee superior battery longevity and operational safety for motorized shades and blinds.
Quick Answer
The Somfy 9028922 offers a dedicated and protected 15V 1A fast-charging solution via USB-C for Somfy's proprietary Zigbee WireFree Li-ion motor systems.
✓Dedicated Somfy Zigbee WireFree Li-ion Fast Charge Protocol (15V DC, 1A)
✓Integrated Multi-Layer Electronic Protection (OVP, UVP, OCP, SCP, OTP)
✓Compact Plug-in Form Factor with Passive Cooling and 5-Year Warranty
The Somfy 9028922 is essential for owners of the latest 2024 Zigbee WireFree motorized shades or external Li-ion battery packs. With its dedicated 15V output and 3-meter USB-C cable, it’s specifically engineered to fast-charge Somfy’s professional shading ecosystem, even on high windows. Buy this for guaranteed manufacturer compatibility and reliability. However, avoid it if you have older RTS motors with barrel connectors or standard 5V electronics, as this 15W brick is hardware-specific for Somfy’s high-performance automation line.
✓ Who Should Buy
- •Owners of Somfy Zigbee WireFree motorized shades or blinds requiring a replacement or secondary charger for their Li-ion battery packs.
- •Professionals installing Somfy smart shading systems who need a reliable and compliant charging solution.
- •Users seeking a CE-certified, dedicated charger that ensures optimal battery health and rapid charging for their specific Somfy devices.
✕ Who Should Avoid
- •Individuals seeking a universal USB-C charger for general electronic devices, as this unit is optimized for Somfy's proprietary battery chemistry and voltage.
- •Users who require a charger for e-bikes or other higher voltage/current Li-ion battery applications, as this 15V 1A charger is not suitable.
- •Those needing a charger for outdoor or harsh environmental conditions, as it is designed for indoor, portable use without ingress protection.
Product Overview
The Somfy 9028922 is a purpose-built AC/DC adapter specifically designed to energize the external Li-ion battery packs powering Somfy's Zigbee WireFree motorized shades and blinds. Operating on a standard 230V AC, 50/60 Hz single-phase input, this compact, matte white plug-in unit delivers a stable 15V DC output at a maximum current of 1A, culminating in a 15W rated power. It leverages Somfy's proprietary Zigbee WireFree Li-ion Fast Charge standard, employing a 2-stage Constant Current/Constant Voltage (CC/CV) algorithm to ensure efficient and complete battery replenishment up to 100% State of Charge. The charger integrates a 3-meter built-in USB-C cable for versatile connection, with an optional 20cm extension (9028565) available for extended reach. A clear LED status display indicates charge completion with a solid green light, simplifying user interaction. Designed and certified to CE standards, the 9028922 prioritizes both performance and safety in a fan-less, passively cooled enclosure.

Engineering Analysis
The Somfy 9028922 is engineered with a robust AC/DC power conversion architecture designed for optimal Li-ion battery management within Somfy's Zigbee WireFree ecosystem. It converts a single-phase 230V AC (50/60 Hz) input into a precisely regulated 15V DC output at 1A, achieving a rated power of 15W. The charging intelligence is built upon Somfy's proprietary Zigbee WireFree Li-ion Fast Charge standard, which employs a sophisticated 2-stage Constant Current/Constant Voltage (CC/CV) algorithm. This methodology ensures rapid and efficient energy transfer during the initial CC phase, safely transitioning to a CV phase to prevent overcharging and precisely achieve a 100% State of Charge, thereby maximizing battery lifespan without equalization or trickle charging.
Thermal management is achieved through an efficient passive cooling system, negating the need for active fans and ensuring silent operation and enhanced reliability by minimizing mechanical wear points. This fan-less design, housed within a compact plastic enclosure, is well-suited for its 15W power dissipation under typical indoor operating conditions, further safeguarded by an integrated Over-Temperature Protection (OTP) circuit.
Critical to Li-ion battery safety, the 9028922 incorporates a comprehensive suite of electronic protection features, including Over-Voltage Protection (OVP), Under-Voltage Protection (UVP), Over-Current Protection (OCP), and Short-Circuit Protection (SCP). These safeguards actively monitor and regulate output parameters to prevent damage to both the charger and the connected battery pack. The presence of electrical isolation further enhances user and system safety by preventing direct current flow paths between AC input and DC output circuits. While reverse polarity protection is not explicitly integrated into the charger unit, the closed-loop Somfy system is designed to prevent such misconnections.
