So I have an extra 100w 18v solar panel and want to build a solar only fan for day time summer use.
I intend to buy a 14 inch Radiator Fan that is rated at 90w and 12v.
I also will get a DC Speed Controller with Reversible Switch rated at 6A DC 10V-60V
My question is should I just run this direct or add in a cheap solar controller ( one that I have CMTD 2420 ) and a Capacitor?
I am just looking for something to buffer the load.
I have a few still good 12v 6 ah batteries, Yet if it dies will it still keep working as it should?
I do have a bad 12v 6ah battery, If I were to hook this up, where should I run the load off the battery or off the charge controller?
