Hello,
So I was in the solar panel section at the market the other day, and I came across an evaporative cooler (swap/desert cooler) that runs on 12v DC.
Very much similar to this one (https://www.alibaba.com/product-deta...838.0.0.ZIyC0v)
But the specs on the one that I found were :
Rated Voltage: DC 12V
Power: 100W
Airflow 2500m3/h
Rated Current,Max: 12A
Water Tank Capacity: 20L
The seller told that he will give me a special price if I buy it with the following:
1) 150w 12v solar panel
2) 100 amp battery ( as he put it "gel battery not car battery")
3) Charge controller
After her did some calculations, he promised me that the unit will run at least 12h a day. And if I want it to run 24h I should get another battery. But what I had in mind was totally different.
My plan is to wire the panel directly to the unit, and whenever the sun is out, the cooling starts. After hearing my plan, he assured me that it will never work, and that I will end up buying the
battery and the charge controller anyway.
My question is: can I run the unit without the battery and the charge control, and only have it run when the sun is up?
for example: Solar panel --------> unit. (direct setup, nothing in between)
Will a 150w 12v panel suffice, or should I get another one and wire them in parallel?
If i get a 250w 18v panel, will the 6 extra volts damage the motor?
PS: This is not the main cooling method for the space.
Kind regards.
