Can watts be different if voltage is the same?
Watts and volts are not independent of each other. Watts cannot exist without volts since they are the product of a combination of volts and amps. In basic terms and using the hydraulic analogy, volts are similar to pressure and watts are similar to rate.
Is DC and AC wattage the same?
In most cases, Watts out DC are 75% to 85% of AC Watts. At 100% efficiency, the AC Watts in are equal to theADC Watts out. Watts x time is the energy that is served.
How do I convert DC watts to AC watts?
You get to AC watts by multiplying the PTC DC wattage by the inverter efficiency. Many inverter efficiencies can run around 95%… so just take the DC rating an multiply by . 95. This will be the lowest number of the three.
Can volts be higher than watts?
The measurement taken in volts is easier as compared to watts because watts is the product of the two quantity i.e., voltage and current. The watt is represented by W….Comparison Chart.

Can you convert AC to DC?
An inverter converts the DC electricity from sources such as batteries or fuel cells to AC electricity. The electricity can be at any required voltage; in particular it can operate AC equipment designed for mains operation, or rectified to produce DC at any desired voltage.
What’s the difference between AC and DC wattage?
Some state incentives specify that they will reimburse a specific dollar amount per AC watt, while others specify a DC watt. (Still, others will award a solar power system owner for every kilowatt hour their system generates, among other methods.)
How many watts are equivalent to 1, 000 watts AC?
1000 Watts is 1000 Joules every second. To provide that power at a lower voltage you increase the current (or vice versa). Power is voltage multiplied by current. 1000 Watts can be 250 volts RMS AC x 4 amps (i.e. 250 x 4 = 1000). 1000 Watts can be 12 volts DC x 83.3 amps (i.e. 12 * 83.3 = 1000).
What’s the difference between PTC and DC Watts?
PTC ratings take into account everything, including loss from wires, etc. You get to AC watts by multiplying the PTC DC wattage by the inverter efficiency. Many inverter efficiencies can run around 95%… so just take the DC rating an multiply by .95. This will be the lowest number of the three. So what should I be quoted in?
What is the power factor of an AC voltage?
The power factor for AC voltage lies between 0 to 1. And the power factor of the DC voltages always remains 1. The polarity of the AC voltage always varies with time, and the polarity of the DC voltage always remain constant. The AC voltage is unidirectional, and the DC voltage is bidirectional.
