C = xT. AC and DC are electric supply current adaptors. This article will discuss the conversion of DC voltage to AC voltage, DC power, and amp rating. Calculation of AC Single phase Kilowatts to amps I (A) = 1000 x P (kW) / (PF x V (V)), which means that the phase current in amps is calculated by multiplying 1000 by the power in Kilowatts dividing the result by the power factor multiplied by the RMS voltage in volts. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. power factor PF times the line to neutral RMS voltage VL-N in volts (V): Do not use typical power factor values for accurate calculations. terminal velocity of raindrop calculator anon ib . The formulas youll use are the following: AC Watts = (DC Watts * inverter efficiency rate) / 100, AC Amps = (DC Amps * inverter efficiency rate) / 100. Note that when we do this calculation, were making the assumption that theres no resistance in your appliance wiring. The formula for finding an amp is, I=P/V. For example, if your pump is drawing 120 A and you want it to run for 24 hours. Some important things for the conversion of DC amps to AC amps. There are a few steps, but theyre not difficult to understand. The average power P in watts (W) is equal to the energy consumed E in joules (J) divided by time t in seconds (s): P (W) = E (J) / t (s). If P is 2500 watts, the voltage is 220 V, and the power factor is 0.8. You see, "amps" can't flow unless work is being done, and then things are OK already. These can be frustrating, especially when your solar system is your primary source of power. What is the difference between AGM batteries and Gel batteries? Manage Cookies.
