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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eFull Control with Wireless V4 Remote\u003c\/strong\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWhy the SolarKing Outperforms a Whirlybird\u003c\/strong\u003e\u003cbr\u003eTraditional 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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eSmart, Sun-Powered Operation\u003c\/strong\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eHow It Works\u003c\/strong\u003e\u003cbr\u003eThink 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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eFor 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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eLet the Sun Do the Work\u003c\/strong\u003e\u003cbr\u003eIf 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.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWhat's New in the V4\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-weather power option:\u003c\/strong\u003e Connect the optional 15V\/240V AC power supply to keep the fan running after dark.
