BATTERIES AND CONVERTERS

Herein lies the problem!!! You are quite correct in your formula. The problem is it is the wrong formula. 1800 watts / 100 volts= 18. The problem is to get 18 amps of 120 volts you must do this. Watts = amps x volts. To get 18 amps of 120 volts from 12 volts you must multiply by 10. With this formula you need 180 amps of 12 volts. ................
