DESCRIPTION
Beat the Australian Heat, Naturally
Australian summers are getting hotter — and so are our roof spaces, often reaching 50–70°C. The SolarKing V4 solar-powered roof ventilation fan is designed to pull that heat straight out, keeping your home or business genuinely cooler without running up your energy bill.
Full Control with Wireless V4 Remote
The V4 wireless remote lets you manage every function from the ground: turn the fan on or off, set fan speed (¼, ½, ¾ or full), program timers, and even force the unit on or off outside its automatic 25°C shutdown threshold.
Why the SolarKing Outperforms a Whirlybird
Traditional wind-driven "whirlybirds" only work when it's windy, moving around 100 CBM of air per hour at best. The SolarKing's powerful 35-watt motor — the strongest in its class for residential use — moves over 2,100 CBM per hour, regardless of wind. There's simply no comparison.
Smart, Sun-Powered Operation
The SolarKing only activates once your roof space hits 25°C, so it won't strip away warmth in winter the way whirlybirds do year-round. As the sun sets and the fan powers down, your roof continues cooling naturally, thanks to the heat it already extracted during the day.
How It Works
Think of how the ground floor of a two-storey home stays cooler than the upper level — the upper floor blocks the worst of the heat. The SolarKing does the same for your whole house: it replaces hot trapped roof air with cooler outside air, dramatically reducing the heat pushing down into your living space.
For even better results, pair it with closable ceiling vents positioned near the centre of your home. Open them during a cool change to draw fresh air in through open doors and windows — the SolarKing then pulls it straight through your roof space.
Let the Sun Do the Work
If you're ready to make a real difference to your home's comfort — and cut back on air conditioning costs — the SolarKing harnesses free solar power to do the heavy lifting, so your AC doesn't have to.
What's New in the V4
- All-weather power option: Connect the optional 15V/240V AC power supply to keep the fan running after dark. It automatically switches to backup power when solar input drops, then back to solar once the sun returns — always shutting off below 25°C.
- Constant-speed motor: Prevents sudden speed surges or drops for smooth, quiet operation.
- Last-setting memory: Remembers your remote-set speed even without the optional power supply connected.
- Anti-mould protection: Automatically runs for 15 minutes a day when no power supply is connected, keeping air moving through your roof space.
- Built to last: Electroplated steel body and brackets (rust-resistant), aluminium flashing and fan cap, stainless steel fasteners.
- Premium packaging & warranty: Comes in a heavy-duty gift box, backed by a 3-year warranty.
