![]() Since they measure two different units, kW cannot be directly converted to amps. Kilowatts is the measure of power, whereas ampere is used to describe current. That means a 24V 60Ah battery stores more energy compared to 12V 100Ah. In contrast, for the 24V 60Ah battery, the kWh will be 1.44kWh. For example, when we compare a 12V 100Ah battery and a 24V 60Ah, it's better to calculate kWh in each case.įor a 12V 100Ah battery, the kWh will be 1.2kWh. Kilowatt-hour = (100Ah × 12V) ÷ 1000 = 1.2kWhĪh to kWh conversion is vital in comparing batteries of different voltages. In this example, we suppose the battery has 100 amp hours and a voltage of 12V. The first step is to locate its amp-hour and voltage, which are often printed on the battery. Suppose you want to calculate the kilowatt-hour of the battery. If you want to convert Ah to kWh, you'll need to multiply amp hours times volts divided by 1000. If you want to determine which battery capacity will meet your electricity needs, you'll need to convert kWh to Ah. Electrical energy is usually measured in kWh, whereas battery capacity is rated in Ah. ![]() KWh to Ah conversion is of utmost importance when estimating the battery capacity. In contrast, amp-hours is the charge that moves through the source in one hour. Ampere is the rate at which electrons pass through an electrical conductor. ![]() That is, the electrical charge in amp-hours equals the energy in kilowatt-hours times 1000, divided by voltage.Įxample: Let's convert 6kWh at 120V to Ah.Īlthough both amps and amp-hours measure electrical charge, they are different. Since energy usage is generally listed in Wh or kWh, calculating the battery's kilowatt hours will help determine how long the battery can power any device or appliance.Ĭonverting kWh (electrical energy) to Ah (electrical charge) can be done using the below formula. Kilowatt-hour = 20A × 120V × 4H / 1000 = 9.6 kWh.Īmps to kWh calculation is helpful when sizing the power station or battery. Let's say you are running a 20 amps electric device on a standard 120V circuit for 4 hours. The formula to convert amps to kWh is given below: Line-to-Neutral Voltage: Also called phase voltage, it is the voltage between any given phase and neutral. Line-to-Line Voltage: Also called line voltage, it is the voltage between any two given phases. The kilowatt-hour, in this case, is nearly 6kWh. Let's say you have an electric device running on a standard 120V circuit for 5 hours. If you want to convert kWh to Amps, you can use the below formula: It is the amount of power a battery or power station can hold. Milliamp-hour, abbreviated mAh, is a commonly used electric charge unit that describes small battery capacities. One amp-hour charge equals one amp of current transferred in one hour. It is the rate of speed at which electrons flow through a conductor.Īmp-hours, abbreviated Ah, is a term that measures electrical charge or battery capacity. One kilowatt-hour of energy equals one kilowatt of power consumed in one hour.Īmps or amperes is a standard electric current unit. Kilowatt-hour, abbreviated kWh, is a term that measures electrical energy. Watt-hour, abbreviated Wh, equals one watt of power or output expended in one hour. Built with industry-leading BMS technology Multiple output ports to charge appliances ![]() Jackery Explorer 2000 Pro Portable Power Station The Explorer 2000 Pro, for example, has a capacity of 2,160 watt-hours and features various ports, including AC outlets, USB ports, DC outputs, and a 12V carport. Jackery offers a line of portable power stations with high capacity and multiple ports. You can convert kWh to amps using the formula: amps equal to wattage divided by volts. On the other hand, amps measure the amount of current flowing through an electrical circuit. The line to Line voltage Calculation Example: Amps:ĭo not use standard power factor values for exact calculations.KWh stands for kilowatt-hour, and it is a unit of energy. Line to line RMS voltage VL-L in volts (V) divided by 1000: The power P in kilowatts (kW) is equal to the square root ofģ times the power factor PF times the phase current I in amps (A), times the Line to neutral voltage Calculation Example: Neutral RMS voltage VL-N in volts (V) divided by 1000: Power factor PF times the phase current I in amps (A), times the line to The power P in kilowatts (kW) is equal to 3 times the In contrast, between a LINE and another LINE (consuming triple phase) wire, the potential difference is 440V. So, if you measure the potential difference between a LINE wire and a NEUTRAL (consuming single phase) wire you will get 220V. There are 3 LINE wires (current carrying) in a 3-phase supply at 120 degrees out of phase with each other and one single neutral wire.
