Losing attic ventilation once the sun goes down means heat and moisture just sit there, we see it all the time with passive setups.
The 40W panel puts out 19.5V and the lithium battery holds 9.6Ah at 16V, charging in about 5.5 hours of good sun and then it'll keep teh fan running for 23 to 25 hours straight.
1650CFM through a 14-inch duct is enough for most residential spaces, and the smart controller handles the switch between solar and battery automatically—you don't hear it click over, which is nice.
It's CE certified, usually ships with a 3-meter cable attached, and the metal housing holds up fine exposed to weather (though direct salt spray near the coast is probably not its favorite enviroment).
MOQ is typically 50 units or so for custom color or logo on housing, lead time runs about 20 days after order approval but we usually have stock on black standerd housings.
Also, the built-in controller pretty much eliminates extra wiring complexity, so you save a bit on insallation time compared to systems where you're buying separate charge controllers.
You get 23 to 25 hours of continuous discharge from the 9.6Ah lithium battery at 16V, so it runs all night and most of the next day even without direct sun.
We don't have a strict MOQ for this model, so 10 units is fine. Just keep in mind that custom packaging or labeling might have a small minimum if you need that.
It's CE certified, and we can provide the CE declaration and test reports on request. If you need specific certifications for your country, let us know and we'll check what we have.
The standard cable is 3 meters, which works for most roof setups. If you need a longer cable, we can customize it for you—just tell us the length when you order.
It's shipped in a sturdy box with foam padding, and yes, it includes the mounting brackets and hardware for roof installation. No extra packaging fees, but let us know if you need the box branded.
