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.

Delivery and Shipping
At Bushline, we believe getting your gear should be easy. That is why we offer Free Standard Shipping to every customer in Australia and New Zealand. No minimum spend, no surcharges.
How Long It Takes
We quote these times from the day you place your order, not from the day we dispatch it. That is the number that actually matters to you, and quoting it any other way just moves the goalposts.
- Most gear: 10 to 14 days from the day you order. Allow up to 3 weeks.
- New Zealand: Same as above. NZ orders run to the same timeframe as Australian ones.
- Large wind turbines: Allow up to 5 weeks. These are heavy, oversized units and they travel on slower freight than everything else.
- Regional & remote areas: Please allow extra time on top of the above.
Dispatch & Tracking
- Pick & Pack: We aim to dispatch within one business day (Monday to Friday). Most orders go out within two.
- Weekends: Orders placed on weekends or public holidays are processed the next business day.
- Tracking: You will get a Shipping Confirmation email with your tracking number as soon as your order ships.
If Your Order Is Running Late
Ring 0400 333 898 or email Support@BushLine.com.au and we will chase the tracking ourselves rather than sending you off to do it. You will get a straight answer on where it is, including if it has not moved.
Need A Large Turbine Sooner?
Expedited freight is available on the big units at extra cost, which brings delivery down to roughly a fortnight. It is quoted per order because it depends on the size of the unit and where it is going. Get in touch before you order and we will price it for you.
Off-grid and hybrid only. Mains in, never out.
A shed with a welder, a compressor and a drop saw in it will overload a small inverter the first time two of them run together. Same story in a cabin — the fridge is no trouble until someone puts the kettle on. The part that gives up is rarely the battery bank. It is an inverter sized for camp lighting being asked to do house work.
This is a hybrid inverter-charger with the solar controller built into the same box. Two ratings: 4.2kW into a 24V bank, or 6.2kW into a 48V bank. Both carry a 120A MPPT controller, a 100A AC charger, pure sine wave output at 220, 230 or 240VAC and two switched AC outputs, so one unit does the work of a separate inverter, solar controller and battery charger. It will run a shed or a cabin off the bank and the array, take a generator or a mains supply in through the AC input to charge that bank when the sun has not done the job, or run straight off the panels in daylight with no battery connected at all.
Read the limits before you buy. We sell and support this one for off-grid and hybrid use only. The AC input takes power in to charge the bank — it is not there to send power back out, and this unit must not be connected to the grid. The reason is set out in full above the spec table and in the Q & A. Any 240V wiring is a licensed electrician's job. Wi-Fi is fitted to two of the four variants, not all four. And your panel string has to sit inside the MPPT's 60–450VDC tracking window, not the 500VDC absolute ceiling: size the string on 450V, not 500V.
What It Solves
- Farm shed on a bank: the welder and the compressor both want to start at once, and the little inverter that ran the lights shuts down every time.
- Daytime-only workshop: you only work in there between smoko and knock-off, so you would rather spend the money on panels than on a battery bank you never use after dark.
- Bush cabin or shack: the fridge has to hold overnight while the kettle, the pump and a power tool come and go through the day.
- Generator running all day: the genset idles away burning fuel to keep the bank up, when it could put 100A in over a short run through the AC input and then be shut down.
- Storm season on the array: summer storms come through most years, and you would rather the surge stopped at the PV arrester than came down the string into your battery bank.
Key Features
- Two ratings, two banks: 4.2kW runs on a 24V bank, 6.2kW runs on a 48V bank. The bank voltage decides the model, so pick the pair together.
- 120A MPPT built in: up to 6,200W of panels on the 4.2kW model and 6,500W on the 6.2kW model, with no separate solar controller to buy or mount.
- String voltage window: the MPPT tracks 60–450VDC and the absolute maximum DC input is 500VDC. In hybrid mode the array has to reach 90VDC to start up and 120VDC before it starts feeding the load.
- Adjustable second output: the secondary load is settable from 20% to 70%, and it drops out on battery voltage — 26VDC on the 24V model, 52VDC on the 48V — coming back at 27VDC and 54VDC. Fridge on the primary, tools on the secondary.
- 100A AC charger: a generator or a mains supply wired to the AC input charges the bank at up to 100A. That is power coming in, not going out, with solar and AC together capped at 120A.
- 94% in battery mode: that is the supplier's DC to AC figure for running the load off the bank, which is the number that matters when there is no mains anywhere near you.
- Pure sine at 240V: nominal output is selectable 220, 230 or 240VAC — set it to 240V for Australian gear. Output range 195–253VAC, power factor above 0.99.
- Runs with no battery: in daylight it will hold a 240V load straight off the array with nothing connected to the battery terminals. Output follows the sun, so it suits tools rather than a fridge.
- Breakers and arrester: AC and PV air circuit breakers and a PV lightning arrester are built in, so a surge on the incoming line or the array is isolated before it reaches your gear.
- Comms and monitoring: RS232, RS485, GPRS and a lithium battery BMS port on all variants. Wi-Fi is a variant option — two of the four are listed with it, two without.
- Size and conditions: 602 x 358 x 113mm, 12.9kg for the 4.2kW and 13.3kg for the 6.2kW, rated −10°C to 50°C and shipped with an anti-dust kit.
Where This Fits
This is one part of the gear that sits between a wind turbine and your battery bank. Here's the whole picture:
- Wind turbines: vertical axis turbines from 1kW to 20kW — quiet enough to put near the house, and they charge overnight when your solar can't.
- Hybrid MPPT controllers: you can't wire a turbine straight to a battery. The controller rectifies the output, manages the charge, and brakes the turbine when the bank is full.
- The rest of the electrical range: bus bars, breakers, isolators, cable, lugs and Anderson plugs.
Every input and output wants a breaker or isolator on it, so you can safely shut down and isolate the turbine before you touch anything. That protects you, and it stops a surge damaging your new turbine or the rest of your power system. Cable sizing depends on your run length, voltage and current — if you're building 12V or 24V, check the sizing against your own run or ask your sparky.
Q & A
Can I connect this to the grid?
No. An inverter connected to the grid in Australia has to comply with AS/NZS 4777.2 and be on the Clean Energy Council approved inverter list. This one is supplied with neither — the data sheet lists CE, RoHS and FC, with no RCM mark and no AS/NZS listing — and your network operator checks that listing before they approve a connection, so the application will not get up. We sell it for off-grid and hybrid use instead: a shed, cabin, homestead or workshop running off a battery bank and solar, with a generator or a mains supply wired into the AC input to charge the bank when the sun has not done the job. Taking power in to charge is a different thing to sending power out, and it is the AC input this unit is sold for. Either way, any 240V work is a licensed electrician's job.
Can I run it off a generator?
Yes, and that is one of the reasons to buy it. The AC input accepts 90–280VAC or 170–280VAC depending on the setting, and the charger will put up to 100A into the bank. The usual pattern is to run the genset hard for a short stretch, get the bank up, and shut it down again, rather than idling it all day. Max AC input current is 24.7A on the 4.2kW and 36.4A on the 6.2kW, so size the genset and its lead accordingly.
Can I run 240V tools off it with no battery bank at all?
Yes, in daylight. The unit will run a 240V load straight off the array with no battery connected. The catch is that when cloud comes over or the sun drops, the output goes with it — there is nothing holding the load up. If you need power after dark, through a cloud bank, or for anything that must not be interrupted, you need a battery on it.
How many panels can I put on it, and what string voltage?
Up to 6,200W of array on the 4.2kW model and 6,500W on the 6.2kW. Size the string so its open-circuit voltage on the coldest morning you get stays under 450VDC, because 60–450VDC is the MPPT's tracking window. The 500VDC figure is the absolute maximum the input is rated to survive, not a working number — do not size to it. The supplier states maximum PV input current as 1/18A on the 4.2kW and 1/22A on the 6.2kW.
Which one do I need, the 4.2kW or the 6.2kW?
Your battery bank decides it as much as your load does. 4.2kW is a 24V unit and 6.2kW is a 48V unit, so if the bank is already built, that is your answer. If you are starting from scratch, add up everything that could realistically run at the same time — a 2.4kW kettle plus a fridge plus a 1.5kW compressor is already past the 4.2kW — and note that the 48V unit moves the same power at half the DC current, which means cheaper battery cable.
Does it come with Wi-Fi?
Only if you order a Wi-Fi variant. There are four: 4.2kW 24V, 6.2kW 48V, and the same two again with Wi-Fi. Two of them have no Wi-Fi module. All four have the RS232, RS485, GPRS and lithium BMS ports.
Does the second output cut off when the battery hits 50%?
No, that is one setting rather than the behaviour. The secondary load is settable from 20% to 70%, and the actual cut-off is a voltage: 26VDC on the 24V model and 52VDC on the 48V, with the load returning at 27VDC and 54VDC. Set it where it suits your bank and your chemistry, not where a sales page tells you.

About the grid-tie rows below: the supplier's data sheet documents a grid-tie mode, and those figures are printed here as published so you can see the whole data sheet. BushLine sells and supports this unit for off-grid and hybrid use only. It is not supplied with AS/NZS 4777.2 certification and it is not on the Clean Energy Council approved inverter list, so it must not be connected to the grid. The AC input is a separate matter — running a generator or a mains supply into it to charge the battery bank is power coming in, not power going out, and that is what the unit is sold to do.

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.
