Start your journey to energy independence today. Join 15,000+ solar enthusiasts breaking free from their energy dependence with this short step-by-step video course that will make you a solar + storage expert. Struggling to understand how solar + storage systems actually work? Looking to build or buy your own solar power system one day but not sure what you need? Just looking to learn more about solar, batteries and electricity? The Ultimate Solar + Storage Blueprint (Mini Course) You can find all of the solar & electrical calculators we have created in order to help you plan, size and install your own solar power system here. You can also make use of our solar load calculator to determine your needs. Once you understand the two variables we’re working with when trying to convert one to another, it becomes much easier than simply rushing into it. The conversion process consists of two straightforward formulae that can be done manually or via an online KVA to Amps calculator. With these values, you can get a better understanding of appliances needed to be powered by your solar system, or better yet, sizing the battery of your DIY solar panel kit.

We eventually end up with 1,101.01A as our three-phase amperage if we plugged in the correct values. We’re still trying to calculate the amperage. Let’s say we have a kVA of 800 again, but our voltage is now 420. This formula states that the three-phase amperage is equivalent to the kVA multiplied by 1,000, dividing that product by 1.73, or the approximate square root of 3, and then multiplying it by the voltage.Īgain, we should use numerical values to show how it works. The three-phase load amperage is a different formula that uses the same variables. If we have a kVA of 800 and a voltage of 230, and we’re trying to calculate the amps, slotting these values into our formula gives us the single-phase amps.

So let’s put this formula to the test and plug in actual values. The formula for single-phase conversion states that multiplying the kVA by 1,000 and dividing that product by the voltage gives you the amperage. This conversion is possible through single- and three-phase loaded circuits, both of which have their own formula. Where some calculators like the inverter amp draw calculator have a single formula to follow, converting kVA to amps is a bit different. If you know two of the values in either of these laws, you can find the current by either multiplying or dividing the values together. Thanks to Ohm’s and Watt’s law, you can easily convert volts to amps or vice versa. This measurement can either be acquired by using an amp meter and connecting it to a point on the circuit, or it can be calculated.ġ A is equivalent to 1 coulomb per second and serves as the base unit of electric current. When you’re using a house amp calculator to see where most of your power is being drawn from in your home, you may notice that the heavier appliances will have ratings in kVA.īut how do we convert this to amperes? More importantly, what are amps and where do we use them in our solar system? What Are Amps?Īn amp is the amount of current flowing from one point to another. To work out kVA, multiply the voltage by the current and divide by 1,000.įor a more practical example with values, let’s say in a given circuit, we have a voltage of 420V, and the current flowing is 32A. These are the same variables you need for a VA to amps calculator. CalculationsĬalculating the kVA of a circuit is a simple formula and you only need to know the voltage and current. In this case, kW is the amount of actual power that does the work, but kVA is merely a fraction of the power that can do the job, while the rest is regarded as the current. However, real power, or kW, will differ from apparent power in AC circuits.
