What is true is that in a 13volt (12 volt nominal) DC system, ran through an inverter that is about 80% efficient, the total power useage is approximently 78 watts, which would be a little under 1 amp at 115VAC. As CLLC is perfectly symmetrical, current can flow equally well in either direction, but as it relies on resonance, it works best with similar input and output voltages. For solar panels, DC watts come in two ratings: Calculating the STC rating of solar panels is straightforward, take the number of watts and multiply it by the actual number of solar panels. With the number of watts and inverter efficiency rate, convert DC watts to AC watts using the following formula: AC watts = (DC watts multiplied by inverter efficiency rate) / 100 For instance: The rating of the monocrystalline panel we mentioned earlier is 330.
