    advice for beginer

    11p x 3,5 amp nominal = 38,5 amp, so I am short 26.5 amps. The 65 amp controller has to get 65 amps or not ? 10 A high discharge battery is for covering of the different in peak in my understading. That set up = long life battery, best to not exceed 1/2 . So 65 Ams/ 5 Amps =13 p , Am I right...

    advice for beginer
