DC Watts and AC Watts are commonly used in electrical power of a unit of measure, especially those involved in the conversion between AC and DC power circuit will often use these two concepts, want to understand the conversion of DC Watts to AC Watts you need to have an in-depth understanding of the two concepts of DC Watts and AC Watts.
1. What is DC Watt?
DC Watt refers to the electrical power in a DC circuit. As a common example, suppose the electrical power output from your solar panels is 200watt, knowing that the power output from your solar panels is DC, so it’s a DC circuit, it can be shown that the DC wattage of this DC circuit is 200watt.
2. What is AC Watt?
AC watt refers to the electrical power in the AC circuit, for example, the DC power generated by the solar panel is converted to AC power by the solar inverter to supply power to the load, then the circuit between the solar inverter and the load is an AC circuit, assuming that the AC power in the circuit is 180watt, then it can be shown that the AC wattage of this AC circuit is 180watt.
3. What is the conversion efficiency of an inverter and how is it derived?
Inverter is a kind of equipment that converts DC power to AC power, the conversion efficiency of inverter refers to the inverter’s ability to convert DC watts to AC watts, the conversion efficiency of different inverters is different, this is because of the difference in the internal structure of each inverter, the general conversion efficiency of inverters is 80%~99%, of course, if you have a higher demand for electricity, you can choose the conversion efficiency of high Inverter.
It is very easy to know the conversion efficiency of your inverter, you can get it from the instruction manual of your inverter.
4. Calculation of DC to AC Wattage
After obtaining the conversion efficiency of your inverter you can complete the DC watt to AC watt calculation.
As an example, suppose the DC wattage of the DC output of your solar system is 2000watt, the conversion efficiency of your solar inverter is 90%, and the AC wattage of the AC side of your solar system is 1800watt by substituting the above formula.
AC watt to DC watt calculation.
Assuming that the conversion efficiency of your solar inverter is 70%, and your load needs 2000watt of power, then you can utilize the deformation formula: DC(watt) = AC(watt)/ inverter conversion efficiency, and substitute the data to get that you need a solar power system that can output 2857watt of power.
Similarly, using the formula: inverter conversion efficiency = DC(watt)/ AC(watt), you can use the calculated data to choose a suitable solar inverter.
5. How can the DC Watt to AC Watt Conversion Calculator help you?
Obviously, the DC to AC wattage calculator can save you a lot of time by eliminating the calculation process. You only need to enter the power output of the DC side of your solar system and the ratio of DC to AC of the solar inverter to get the AC wattage, and I believe that the DC to AC wattage calculator can be a big help in your life.
