10 kW Permanent Magnet Wind Turbine Grid-Tied System for a Lakeside Vacation Cabin in Michigan, USA

Abstract: A lakeside vacation cabin in Michigan, USA, relied on grid electricity with high bills and a desire to use clean energy. GREEF Energy customized a 10 kW permanent magnet wind turbine + GREEF smart controller + Solis grid-tied inverter system (battery-free). After six months of operation, the estimated annual generation is about 17,800 kWh, electricity costs dropped by 78%, saving approximately $7,400 per year, enabling self-consumption with surplus power fed into the grid.

1. Project Background & Challenges

The cabin is located in the northern lake region of Michigan, with an annual average wind speed of 6–8 m/s. The owner's annual electricity bill was about $9,500. They wanted to reduce costs and carbon emissions with clean wind power but did not want the expense of battery storage. A safe, compliant, cost-effective grid-tied solution was required.

2. Customized Solution

·         Generator: 10 kW low-speed permanent magnet synchronous generator, starting torque 0.2 N·m, cut‑in wind speed 2.8 m/s.

·         Controller: GREEF PCTC‑10kW intelligent MPPT controller (overvoltage protection, anti‑islanding).

·         Inverter: Solis grid‑tied inverter, UL1741 compliant.

·         System feature: Battery‑free configuration, simple structure, low cost, direct grid connection – self-consumption plus feed‑in.

3. Implementation & Technical Details

The project was completed and grid‑connected in 25 days:

·         Generator with IP65 protection, suitable for the humid lake environment.

·         System topology: Permanent magnet generator → GREEF controller → Solis inverter → cabin load + grid.

Mobile app remote monitoring of generation and grid interaction, constructed strictly to local grid interconnection codes.
