Somfy 3.2W Solar Panel Instructions Manual

The Somfy 3.2W Solar Panel is designed to power Somfy wireless motorized systems for blinds, awnings, and shades. It provides a sustainable, cable-free energy solution with a 3.2W output, IP65 weatherproof rating for outdoor use, integrated rechargeable battery backup, and compatibility with various Somfy receivers (e.g., Sonesse 30, 40, 50). Below are key sections for safety, features, installation, setup, operation, and troubleshooting.

Features at a Glance

Key components: Solar Panel, Mounting Bracket, Connection Cable, Weatherproof Seal, Status LED.

Installation

Unpack and inspect contents. Ensure all parts are present.

1. Choose Location: Select a south-facing location (Northern Hemisphere) with maximum sunlight exposure, free from shadows.
2. Mount Bracket: Secure the mounting bracket to a wall, roof, or pole using provided screws. Ensure it is stable.
3. Attach Panel: Slide the solar panel onto the bracket and tighten the adjustment knob to desired angle (optimal: 30-45°).
4. Route Cable: Run the connection cable from the panel to the motor/receiver location. Use cable clips if needed.
5. Weatherproofing: Apply sealant around cable entry points if drilling is required.

WARNING! Do not install near heat sources or flammable materials. Ensure mounting surface can support weight.

First-Time Setup

After installation, connect and activate the system.

1. Connect to Motor: Plug the waterproof connector into the solar input port on the Somfy motor or receiver.
2. Initial Charge: Expose the panel to direct sunlight for at least 8 hours to fully charge the internal battery.
3. Check LED Status: Solid green LED indicates full charge; blinking green indicates charging; red indicates error (see Troubleshooting).
4. Test Operation: Use your Somfy remote or switch to operate the motor. It should respond normally.
5. Fine-Tune Angle: Adjust panel tilt seasonally for optimal performance.

CAUTION! Do not connect or disconnect cables in wet conditions. Ensure all connections are secure and dry.

Controls and Connections

The panel has minimal user controls. Primary interface is the Status LED and the connection port.

Status LED Indicators:

• Solid Green: Battery fully charged, panel operational.
• Blinking Green (slow): Charging in progress.
• Blinking Green (fast): Strong sunlight, optimal charging.
• Solid Red: Error - check connection or motor fault.
• Blinking Red: Low battery - requires sunlight exposure.
• Off: No power - check sunlight or physical connection.

Connection Port: Waterproof 2-pin connector. Ensure it clicks securely into the motor's socket.

Connecting to Motors

Compatible with Somfy wireless motors equipped with a solar input.

1. Turn off or disconnect any existing power source to the motor.
2. Locate the solar input port on the motor (usually labeled "SOLAR" or with a sun icon).
3. Connect the panel's cable to the motor port. Twist to lock if it's a threaded connector.
4. Route the cable neatly, avoiding sharp bends or pinch points.
5. The motor should now be powered by the solar panel. The internal battery will charge automatically.

Tip: For new installations, program the motor with your remote before connecting the solar panel.

Charging & Operation

The system operates automatically once connected.

1. Daily Operation: During daylight, the panel charges the internal battery and powers the motor directly.
2. Night/Cloudy Days: The motor runs off the stored battery power.
3. Battery Protection: The system includes over-charge and deep-discharge protection to prolong battery life.
4. Usage Monitoring: Frequent or heavy use may drain the battery faster. Ensure adequate daily sun exposure.
5. Winter Operation: Snow or ice on the panel will reduce output. Gently clear obstructions.

WARNING! Do not attempt to open or repair the panel. No user-serviceable parts inside.

Maintenance & Monitoring

Regular checks ensure optimal performance.

• Weekly: Visually inspect panel for dirt, debris, or shading from new obstructions.
• Monthly: Check cable integrity and connection security.
• Seasonally: Adjust panel tilt angle for changing sun path (steeper in winter, shallower in summer).
• Battery Health: The internal battery has a typical lifespan of 3-5 years. Reduced autonomy indicates replacement may be needed.

Care & Cleaning

Keep the panel surface clean for maximum efficiency.

1. Disconnect the panel from the motor if safe access requires it.
2. Use a soft, damp cloth with mild soapy water to wipe the glass surface.
3. Rinse with clean water and dry with a soft, lint-free cloth.
4. Do not use abrasive cleaners, solvents, or high-pressure water jets.

CAUTION! Clean only when the panel is cool (morning/evening). Do not walk on the panel.
