The solar battery has a capacity of 2.4 kWh. You can convert the 200 amp-hours to kilowatt-hours by simply doing this: Let’s say you have a solar system with a 200 amp-hours (Ah), 12V solar battery, but you want to know the battery capacity in kilowatt-hours (kWh). Example: How to Calculate Kilowatt Hours of a Solar Battery This is what our Ah to kWh conversion calculator and pretty much any other Ah to kWh calculator do. Going by the formula, to convert ampere-hours to kilowatt-hour, multiply Ah & volts then divide by 1000. Power (W) = voltage (V) x electrical current (A) First, since kWh is a measure of electrical energy, we’ll start with its formula:Įlectrical energy (kWh) = power (W) x time (h) ÷ 1000 We’ll start by deriving the conversion formula of ampere-hours to kilowatt-hours. How to Calculate Ah to kWh Conversion Formula However, when it comes to electrical energy, kilowatt-hour (kWh) is preferred. The SI unit of energy, including electrical energy, is Joules (J). It represents the energy used up owing to a given amount of power consumed over one hour. ![]() Kilowatt hours is a unit used to measure electrical energy. Although, in some cases, the metric prefix – milli – may be added to it, changing the unit to mAh. Conversion formula: kWh = Ah × V / 1000 What Is Amp Hour? What Does Ah Mean on a Battery?Īmp-hour (also ampere-hour) represents the amount of electric charge that a power source will discharge within one hour at a given voltage.Īmp-hours (Ah) is used to represent the capacity of most batteries.
