Summary Checklist for Your Choice
Choose the SR or ST-1200W if you want portability, low noise, and minimal investment for camping or caravans.
Choose the ST-2000, ST-3000, or ST-5000 if you have a stationary house/cabin and want to supplement solar panels at night.
Choose the ST-10kW or 20kW if you have heavy agricultural power needs, acreage, and a budget for proper mast engineering.
The vertical axis wind turbines listed on the BushLine Outdoor Equipment catalog are categorized by physical design shapes, which dictate their ideal applications.

No.Wind turbines generate "wild" 3-phase AC power that changes voltage constantly with the wind speed. Connecting it directly to a battery or a standard solar inverter will instantly destroy your equipment. Youmustwire the turbine into a dedicatedWind/Solar Hybrid MPPT Controller with an integrated Dump Load Resistor. The controller converts the power to stable DC to charge your batteries safely.
-
You must match the turbine and its hybrid controller to the exact voltage of your existing battery bank:
- 12V: Best for compact mobile setups like caravans, 4WDs, and camper trailers.
- 24V: Great for medium-sized setups like off-grid sheds, cabins, and motorhomes.
- 48V: The gold standard for full off-grid home systems. Higher voltage means less energy loss through your wires and allows you to use thinner, safer cables.
-
When your battery bank becomes 100% fully charged, it stops accepting power. If a heavy wind storm hits at night when your batteries are full, a turbine with nowhere to send its power will "free-spin" out of control and physically fly apart. A hybrid controller fixes this by automatically diverting that excess power into the dump load resistor, which burns it off safely as heat and acts as an electronic brake to slow the turbine down.
-
No,that is the main benefit of the vertical design. Traditional horizontal "propeller" turbines create a high-pitched, annoying "chopping" noise. Our ST Tulip and Flower series utilise advanced omnidirectional maglev-style bearings, making them virtually silent and completely vibration-free, all you will hear is the wind. They are perfect for suburban blocks, tight caravan parks, and areas close to neighbours.
-
Yes.These turbines have an incredibly low startup wind speed of just 2.0 m/s, meaning the blades will begin rotating in a very gentle breeze. However, please note that physical power generation only starts accumulating once wind speeds consistently clear 4 to 5 m/s.
-
You should connect the wind turbine to a battery bank first, via a dedicated charge controller, rather than directly to an inverter. Connecting a wind turbine directly to a standard inverter will damage the equipment or cause the system to fail.
🔋 The Correct Wiring SequenceTo safely capture and use the power, your setup must follow this exact order:
- Wind Turbine: Generates wild, fluctuating 3-phase AC power as wind speeds change.
- Hybrid/Wind Charge Controller: Converts the unstable AC power into steady DC power. It also protects the turbine from over-speeding by applying an electronic brake during high winds.
- Battery Bank (12V/24V/48V): Acts as a buffer to store the energy. It absorbs sudden power spikes from wind gusts and provides a steady source of energy.
- Off-Grid Inverter: Connects to the battery, converting the stored DC battery power into standard AC power for your household appliances.
⚠️ Why You Cannot Skip the Battery
- Unstable Voltage: Wind speeds change second by second. Without a battery to absorb and smooth out these massive fluctuations, a direct-connect inverter would constantly turn off and error out.
- Turbine Destruction: When a battery is full or disconnected, a wind turbine loses its "load" (resistance). Without that resistance, the blades can spin out of control in high winds and physically destroy the unit. The charge controller uses the battery connection to safely dump excess power and slow the turbine down.
-
Wiring & Installation Requirement:This wind turbine generates 3-phase AC power andcannotbe connected directly to a battery, solar controller, or home inverter. To operate safely, it must run through a dedicatedWind/Solar Hybrid MPPT Controller with an integrated Dump Load Resistor. The dump load prevents the turbine from over-speeding and destroying itself in high winds once your batteries are fully charged.
-
It is almost always caused by one of three common installation errors. Check these variables in order: Checking the Multi-Meter Setting (Most Common Mistake)
- The Issue: The customer is likely measuring the three wires coming out of the turbine using a DC voltage setting on their multimeter.
- The Reality: Wind turbines generate 3-Phase AC power directly from the stator.
- The Fix: Instruct them to switch their multi-meter to AC Voltage (V~). Testing the wires under a DC setting will provide a false, completely inaccurate reading near zero.
2. The Turbine is Stalling Due to Incorrect Wiring
- The Issue: The turbine blades are spinning heavily but turning very slowly or locking up because of an electrical short.
- The Reality: If any of the three AC output wires are accidentally touching each other, or if the controller's internal braking diodes have short-circuited, it creates a magnetic brake. This bogs down the turbine, physically stopping it from spinning fast enough to build voltage.
- The Fix: Have them completely disconnect the turbine from the controller. If the turbine suddenly unbogs and spins much faster when disconnected, the problem is a short circuit in the wiring or a faulty controller.
3. Voltage Drop Caused by Thin Cables
- The Issue: The customer ran thin wiring over a long distance from the tower down to the battery shed.
- The Reality: If they used standard thin solar cables or thin automotive wire over a long distance (e.g., 20+ metres), the natural resistance of the copper wire will choke out the electricity. The energy is lost as heat inside the wire before it ever reaches the meter.
- The Fix: Ensure they are using heavy-duty, minimum 8 AWG or 6 AWG thick cable lines between the mast and the controller house
-
Wind turbines are rated byCumulative Daily Capacity, not instantaneous hourly peak output. Because wind speeds fluctuate constantly second-by-second, a 1200W turbine is designed to yield up to 1200W of total poweraccumulated over a 24-hour periodin optimal conditions (averaging roughly 50W per hour). This constant, steady trickle is exactly what makes vertical turbines perfect for maintaining batteries overnight when solar panels are offline.

Not necessarily — this is one of the most common questions we get, and it's rarely a faulty unit. It's usually a quick settings check, or (on a first-time install) how the wiring and start-up sequence were done. See our full Wind Turbine 0W Troubleshooting & Installation Guide for the complete walkthrough, or contact us and we'll help you sort it out.

Short Answer Wire your bus bar and breakers before and after the controller, then power up in the right order — battery first, then solar, then wind. Getting this sequence right prevents almost all wiring issues, including the common "spinning but 0W" problem. Answer (rich text field, with the link placeholder): Correct installation comes down to isolation and the right sequence: Fit a breaker before the controller (turbine/solar side) and after it (battery side), landing on a DC bus bar Keep the turbine-to-controller cable run to 2–10 metres to limit voltage drop Power up in this order: battery breaker first, then solar, then wind turbine last See our full How to Install & Start Up guide for the complete step-by-step walkthrough and wiring diagram.
