![]() ![]() If the power factor is not provided, it is common to assume a power factor of 1 (unity) for resistive loads or refer to the specifications of the specific device or system to obtain accurate power factor values. ![]() Please note that the power factor (PF) is an important consideration, as it represents the ratio of real power to apparent power. Learn how to effortlessly convert kilowatt-hours (kWH) to amps using a simple formula (AkWH/V1000). In this example, the load has an approximate amperage of 30.8 amps. To use this formula, multiply the power in kilowatts by 1000 and divide the result by the product of the voltage (V) and power factor (PF).įor example, if you have a load with a power consumption of 7 kW, operating at 240 volts with a power factor of 0.9, you can calculate the amperage as follows: The formula for converting kilowatts to amps is: I (A) 1000 x P (kW) / (3 x PF x V L-N (V)). Converting kilowatts (kW) to amps (A) requires knowledge of the voltage (V) at which the electrical device operates and the power factor (PF) of the load. The formula: Ampere hour Watt hour / Voltage 1kW 1000W Refer this link for more information on how to size a battery bank for solar (photovoltaic) panels or other DC power sources. ![]()
