SolarKing Wireless V4 Solar Roof Extraction Fan with Remote Control
Standard freight included within Australia, excluding Western Australia and the Northern Territory. A delivery surcharge may apply to WA and NT orders.
Some days the heat in your roof seems to linger long after the afternoon sun has moved on. On other days, your concern may be damp air or condensation in the roof space. The SolarKing Wireless V4 gives you a way to ventilate that space using solar power, with a remote control when you want a say in how the fan operates.
The fan draws air out of the roof cavity while replacement air enters through suitable eave vents or other roof-space openings. It is sometimes described as a solar whirlybird, but unlike a wind-driven whirlybird, it has a motor powered by its own solar panel. It can actively move air on a sunny, still day when the roof-space temperature calls for it.
A wind driven whirly bird only rotates when wind is prevalent and only moves a small amount of air per hour. The Solarking fan on the other hand will start spinning as soon as the sun hits the panel and can exhaust up to 20 x the amount of a standard wind powered whirlybird.
On a typical hot day, you can leave the Wireless V4 to look after itself. Its temperature control normally starts the fan when the roof space is above approximately 25°C and sufficient power is available.
The supplied wireless remote also lets you:
Turn the fan on or off
Select one of four speeds
Override the usual temperature setting when you want ventilation in cooler conditions
Set a 1, 2, 4 or 8-hour timer
Your chosen speed is saved even without the optional power supply connected. The wireless remote works from up to 20 metres away, depending on its position and any obstructions.
If you mainly want automatic summer heat extraction and are unlikely to use these controls, the Standard V4 may be all you need.
Help your roof space release the heat
Sunlight warms your roof, which in turn warms the air beneath it. When that heat builds up above the ceiling, some can pass into the rooms below. The Wireless V4 extracts roof-space air so that outside air can enter and move through the cavity.
With airflow of up to 2,100 m³ per hour, the Wireless V4 helps clear trapped heat from your roof cavity. Good airflow depends on sunlight reaching the panel and fresh air being able to enter and move through the roof space.
A roof fan works alongside ceiling insulation, shading and a well-sealed ceiling. It is not an air conditioner, and the temperature change inside a home will vary. For a broader look at where solar ventilation can help, read our guide to the benefits of solar powered fans in Australia.
Ventilation during cooler months
Roof ventilation can matter for reasons other than summer heat. Moisture from a leak, a poorly ducted bathroom exhaust or humid air entering the cavity can leave roof timbers and other surfaces damp.
The Wireless V4 has an automatic anti-mould function that runs the fan for approximately 15 minutes once a day when the roof space is below its normal temperature setting and solar power is available. This daily cycle does not require the optional mains power supply. You can turn the function off with the remote if you do not want it operating.
That short ventilation cycle helps move air, but the fan does not remove existing mould or fix the source of moisture. If you are seeing condensation or mould, identify leaks and check where bathroom, kitchen and laundry exhausts discharge. Our guide to mould, moisture and condensation in roof spaces explains these causes and where ventilation fits into the solution.
What happens when the sun goes down?
The fan normally uses its own solar panel. If you want to run it after sunset or when sunlight is insufficient, an optional 240 V AC to 15 V DC power supply is available separately. You will need a suitable power point near the fan’s power connection.
The optional power supply takes over automatically when solar power drops, running the fan at up to approximately three-quarter speed. Use the remote to operate it below the normal temperature setting. After-dark operation requires the power supply.
How many fans will your roof need?
There is no dependable answer based on bedroom count alone. One fan can be a sensible starting point for a compact, connected roof cavity with a good path for replacement air. A long roof, separate wings or divided roof sections may need more than one extraction point.
The number of fans you need depends on the size and layout of your roof space, available sunlight and openings for incoming air. Larger roofs or separate roof sections may benefit from additional fans. Use our Solar Fan Calculator for an estimate.

Our old Solartube fan system was old and was not working well. We selected the Solarking V4 C/W remote and AC backup as a replacement and called SatPlus and left a message and the call was returned. All my questions were well answered; I decided to purchase it, then it arrived and I had it mounted on the roof all within less than a week. The installation went straight forward with no difficulties.
Air flow was about 3m/s with 240Vac (full speed) and 3.4 - 3.6m/s (solar only, supply unplugged) and 4.1m/s outside discharge. Speed does increase when on solar only. I can hear the fan humming on solar only but not as much as the refrigerator, dishwasher or oven.
Functionality; Fan On/Off, 4 x fan speeds work on 240ac and solar (can reduce noise with speed), Remote pairing button, 1,2,4,8hr time delay buttons, and a 25C over-ride.
There is no command feedback to the remote, but I don’t think it is needed as I can hear a light hum change in the ceiling. The 240Vac backup system works day during cloud passing, and also night time delay off.
Because I live in Cairns, the fan regularly starts in the morning and I can let it run another 4, 8hrs after sunset or overnight on the tropical nights.
Overall, my experience was exceptional, every question asked was answered thoughtfully and respectfully, ordered, delivered, working in under a week is right up there with the best. To get both service and performance in the one package is commendable. Not overstated or underdelivered.

I would have to say that this has been one of the best purchases I’ve ever made hands down.
Not having Aircondioning due to a house fire and the time of year, trying to get any trades in is next to impossible.
I was going to buy a couple of whirlybirds, but the cost of them is ridiculous compared to the cost of this little gem.
The temperature today is 41 degrees Celsius, without having installed this last night the inside of the house, although it is extremely well insulated, would have warmed up like an oven and held the heat over night, having yet another hot sleepless night, although we are going to need to purchase another two for the house due to the size and the way the roof is pitched, I’m also going to be purchasing another three for the shed, I’m blown away by the performance of this little Rippa and would highly recommended this product, as I already have to everyone I’ve been in contact with already.
I can’t thank these guys enough, I purchased it on Sunday afternoon and it arrived Tuesday morning, that alone blows my mind, I can’t get something out of Melbourne over night, but I can’t get this from Queensland, delivered to my door at Baranduda (a little suburb just out of Wodonga) pretty much overnight.
It has been an absolute pleasure being able to purchase and install this product, I just can’t believe that it was installed within 48hours of making the purchase.
Well done to you guys, this is exactly how you operate a business, it’s great to see and you are setting the standard for every industry in my opinion.
I will be definitely interested to hear what my wife thinks when she gets home from work, I have no doubt she will be dreading it as she normally is due to how hot it can get, but she is in for a huge surprise that’s for sure.
Many thanks again, this has been a game changer!

Records up to 10 programs at once including terrestrial channels. It took me a fare amount of time navigating the settings, but there are handy methods of setting the precise recording times.
I also noticed that the colour of the Hisense TV screen displayed by the UEC channels is softer than the screen displayed by the Hisense channels.
Overall, it is well worth the change over from earlier Altech UEC and then the Humax which both could not allow chase play without jumping out of the recording at the point of starting to watch the program while it was still recording.
Service and delivery was quick. I installed recently and so far, it's working very well. Note, there were a couple bolt and nuts missing for the panel bracket but a Bunnings visit fixed that.
