The solar roof ventilation fan (also home solar system) here is an amazing day-night-nonstop & smart vent unit that includes a solar battery kit to realize free energy backup even in night time periods, say this HVAC (Heating, Ventilation and Air Conditioning) system is 24 hours and absolutely solar panel powered off-grid!
general electrical & mechanical parameters:
Fan Cover | dia.530mm Round shape, galvanization steeling with outdoor standard powder coating |
Solar Panel | 40W/21V, polycrystalline cells, 495*495*25mm tilting & angle adjustable; serve as main power when sunlight is available |
Wind Guide Cone & Wind Guide Blades | SIPL patented ventilation structure; benefits for a higher air extrction efficiency |
Air Duct | 14'', dia.368mm |
Fan Motor | IP68 brushless DC motor (SIPL patented fan motor) |
Fan Blades | 14'', 7 blades, nylon-fiber-aluminum compound unique fan blades |
Fan Base | 530*530mm Square shape & flat, detachable from fan host, galvanization steeling quality |
Fan Host Size | 530*530*255mm (when solar panel is fixed horizontally) |
Unique Brushless DC Motor:
Our solar attic fan will start and keep running once sunlight is available, own to it is equipped with a best motor. This engine is IP68 waterproof, to assure the fan be suitable to install anywhere:
Patented Ventilation Structure:
Our solar attic fan is an axial flow type roof ventilator, but it is made with a 360-degree swirl turbin air ventilation structure
to guarantee no backward air flow from the exterior. This is essential & beneficial:
Smart System Controller:
When our solar fan is to connect with a solar battery kit for day-night air ventilation, a Smart Controller is assembled to automatically take care of all power supplies from (or shifts between) its solar panel & battery, and you don't need to do anything nor worry about how to have the fan run by solar panel at sunny hours while by battery in sunless periods!
Reliable Product Performance at Easy Installation:
Being a self-contained solar ventilation roof fan, our equipment will work friendly & reliably after you put it onto the building roof. Moreover, own to good product strucure and off-grid solar feature, our solar vent would effectively reduce the possible maintenance trouble for you in future!
Solar Battery System Part:
general electrical & mechanical parameters:
Solar Panel | 30W/16.5V, polycrystalline cells, 415*495*25mm tilting & angle adjustable |
Battery | 9.6Ah*12.8V, high quality lithium storage battery; can be charged full in about 5.4 strong sun hours during day time; can backup the fan for 19.2 sunless hours (discharge only when the fan's PV output is insufficient) |
Dimension | 415*500*67mm (when solar panel is fixed horizontally) |
Cable | include 3m cacle to connect solar battery kit with solar fan |
Given sunlight condition varies in different areas, different solar battery kits are available for you, aiming to have battery be sufficiently charged enough in day-time to backup the fan's night-time rotation:
More Solar Battery Kit # | SN2013011 | SN2015024 | (as per your customization) |
Solar Panel | 20W/16V | 40W/16.5V | > 40W |
Time to Fully Charge Battery | 7.7 strong sun hours | 4 strong sun hours | shorter than 4 strong sun hours |
However, if grid electricity is available in the application site, and you have budget on product cost, you can take AC/DC Power Adapter instead of Solar Battery Kit to also realize the fan nonstop running at night:
