Hello sir , I’m Mexican American born and raise in Miami Fl ! When I see your videos I see myself a lot in living I have been repairing electrical equipment for over 25 years and still going working 7days a week and nights don’t stop till your done with one or the last repair of the day. ! I have been into solar for about 8 years already but I’ve learned to homework first before jumping in so battery buying has just started I have been trying to reach for some advice?? For you and want to see simply take OFF BIG

Thanks for the note. It is appreciated.

3:53 - You could measure the voltage over the two pins which are driving the fan, so you could see if the controller is sending the voltage to the fan, but the fan is simply not spinning. Normally this fans have 3 pins, +5V/12V/24V/48V, GND and Clock signal. With the clock signal the controller can measure, is the fan still spinning or not. But check the voltage of the fan and what he get from the mainboard. If he get 48V and he is a 12V fan, then he get to much power. I think you overdrive this fan right now. Better you find a matching fan with the right size (hole distance is 90mm or 120mm ?) and matching voltage. Right now he will do the job, but he will not do it for long in this way. If you use a resistor to reduce the power, then you should use possibly 100 Ohm or 200 Ohm. It depends on the current of the fan, the input voltage what the fan should get and the voltage the mainboard sends him. If the board sends 48V, the fan need 12V/0.15A then it is (48V-12V)/0.15A = 240 Ohm The heat what the resistor creates is (48V-12V)*0,15A = 5.4 Watt.

You are right. I didn't think of all the stuff you said. The fan that I bought was 12/24/48v. It should be ok.
