Greetings all,
I bought a solar powered attic fan that I would like to also run via ultility power. The motor is rated for 36volts DC/13amps(stated on label). The panel is only a 30watt, so I figure 18v at approx 2-3 amps. What are some ideas for attaching to ultility. I have access to a13v/13amp power supply which I get a large pot for or can I just hook up a large rheostat directly to a 15amp outlet?
