Can You Add a Wind Turbine to a Solis System?

Many Irish homeowners are now choosing to combine solar and wind for a more balanced renewable setup — solar in summer, wind in winter.
If you already have a Solis S6-EH1P5K-L hybrid inverter, the good news is that you can integrate a small domestic wind turbine safely and efficiently.

⚙️ What You’ll Need

• Small wind turbine (1–5 kW)
• Wind rectifier (converts 3-phase AC from turbine to DC)
• Wind charge controller (regulates battery charging voltage)
• Battery bank (e.g., Pylontech, Dyness, BYD — same as your PV system)
• Dump load resistor (safely absorbs excess energy when batteries are full)
• Breakers, isolators, earthing, and proper cabling

🔋 How It Connects

Your hybrid Solis inverter handles solar panels on its DC inputs, and the battery bank on its storage terminals.
The wind turbine connects to the battery side, not the solar side.

   Home Loads / Grid

✅ Result: Both solar and wind feed into your battery system. The Solis inverter then manages power to your home or exports excess to the grid.

🧱 Installation Steps

1. Mount the turbine on a tower at least 10 m tall, clear of trees/buildings.
2. Wire the turbine to a rectifier to convert 3-phase AC → DC.
3. Connect DC output to a wind charge controller rated for your turbine voltage (usually 24 V or 48 V).
4. Install a dump load to protect batteries from overcharge.
5. Connect the controller’s DC output to your existing battery bank (the same one used by your Solis inverter).
6. Check system grounding and install surge/lightning protection.
7. Power up and test: The wind controller should show charging voltage when wind speed exceeds cut-in.

✅ DOs and ❌ DON’Ts

✅ DO:

• Use a wind-specific controller, never a solar MPPT.
• Match turbine voltage (24 V / 48 V) to your battery bank.
• Keep turbine tower and cables earthed.
• Include a manual stop switch or brake for safety.
• Monitor performance regularly, especially in winter months.

❌ DON’T:

• ❌ Connect the turbine directly to the Solis PV inputs — this can damage your inverter.
• ❌ Skip the dump load or fuse protection.
• ❌ Install turbines on rooftops — always mount on a dedicated pole.
• ❌ Mix DC voltages from different systems without proper isolation.
• ❌ Ignore wind siting — poor exposure drastically reduces output.

🌍 Why It’s Worth It

• Solar performs best in bright months.
• Wind peaks during darker, stormier seasons.
  By combining both, your energy generation stays consistent all year, and your battery bank stays charged even when solar yield drops.
