Lernen:Ampere-zu-Watt-Rechner

As more and more homes adopt and use solar panel systems, choosing the right solar panel size has become a hot topic. Without an understanding of the meaning of the relevant physical quantities and the formulas used to calculate them, this choice becomes difficult.

In diesem Artikel, we will learn the units of measurement for two common physical quantities, the amps to watts, and the conversion formula for the amps to watts calculator. This can help you better determine the scale of solar panel system required for your home.

What is the ampere (EIN)?

The ampere is the unit of current (ICH) in A circuit, abbreviated as the ampere and symbolized as A. Current is the rate of flow of electric charge per unit time. One ampere (EIN) is equal to one coulomb (Q) per second (s).

It is usually used to describe the amount of current in a circuit. From a microscopic point of view, it expresses the amount of charge that passes through a section of the circuit instantaneously, das ist, the rate at which the current passes through a section.

What is Watt (W)?

Watt is a unit of power, a combination of amperes and volts. It is often used to describe the amount of electricity consumed by an electrical system to complete a job. The larger the watt value, the more electricity the appliance consumes, and the smaller the watt value, the less electricity it consumes.

It is usually used to measure the power of various small and medium-sized household appliances and some components in solar panel systems. Imagine a heating system like an oven. The higher the wattage of the oven, the faster the food will cook.

The importance of convert amps to watts

There are many calculators and converters available on the network, such as ampere-to-watt calculators, ampere-hour calculators, ampere-hour-to-watt calculators, und so weiter.

To ensure compatibility with your home or business power system, it’s important to know the amps, Volt, and watts of your equipment. By mastering two electrical parameters, you can calculate the third, which is essential to ensure the safe and efficient operation of the equipment. Lack of proper conversion can lead to damage to electrical appliances and solar systems.

A faulty power connection can cause circuit failure and is a major cause of early failure of electrical equipment. Precise execution of these conversions is essential to prevent long-term damage to solar systems.

How to convert amps to watts ?

After understanding the basic units of physical quantities, we can begin to learn the formula for converting amperes to watts. Considering the differences in the characteristics of AC (Wechselstrom) and DC (Gleichstrom) circuits, the method of converting amperes to watts is not the same, so the following will explain the conversion formulas of these two different circuits.

Direct current circuit overview

In a direct current circuit, amperes and watts represent different physical quantities, with amperes being a unit of measurement for current, and volt-watts being a measure of power. To convert between the two, we need to introduce an intermediate physical quantity, the volt (v).

Easy conversion with the following formula:

P (W) = I (EIN) x V (v)

In the formula, P is the power in the DC circuit, I is the current in the DC circuit, and V represents the voltage in the DC circuit, namely:

Watt = amperes x volts

In order for you to better understand and apply the formula, the surface is an application example.

Suppose you intend to install a solar power system for your home, the known voltage of the home circuit is 110 Volt, and the total current requirement of your home appliances is 10 Verstärker. The solar panel you need should be able to produce:

10A×110V=1100W

That’s 1100 watts of electricity to meet your power needs.

Ac circuit Overview

Compared with the stable and constant current and voltage of the direct current circuit, the characteristic of the AC circuit is that the current and voltage change periodically according to the law. daher, the formula for converting amperage to wattage of AC circuits may be more complex.

After you understand the simpler DC circuit formula above, the formula for AC circuit amps to watts is described below.

Most of the electrical equipment used in our daily life relies on AC circuits for power supply. Even the direct current emitted by the solar panel system needs to be converted into alternating current by the inverter to power the device.

Ac power is divided into two main categories: single-phase AC and three-phase AC. These two types play an important role in different application scenarios.

Single phase alternating current

A single-phase alternating current (Wechselstrom) is a system in which there is only one AC voltage in the circuit, and the current and voltage generated in the circuit change with time at a specific frequency.

In single-phase AC, the formula for converting amperes to watts is:

P（W）= PF × I（A） × V（v）

Here are some explanations of the above formula:

P stands for the power produced by the electrical system, in watts (W).

V refers to the effective value of the voltage, das ist, the DC voltage in the circuit that can produce the same heating effect. Since the voltage in an AC circuit varies with time, calculating its RMS value helps simplify the calculation of power.

I represents the current in the circuit in amperes (EIN).

PF is the power factor of a single-phase AC circuit, das ist, a value used to measure the phase difference between voltage and current in the circuit. The lower the power factor, the greater the phase difference between voltage and current, which will lead to the reduction of circuit efficiency and the corresponding weakening of system stability.

Three-phase alternating current

Three-phase alternating current is the most commonly used alternating current in practice, which is composed of three alternating current potentials with the same frequency, equal amplitude and 120° difference between phases.

In three-phase AC, there are two ways to calculate the ampere to watt conversion formula:

1. Use voltage between lines (V LL) for calculation:

P= √3 × PF × I × V L-L

Hier, P stands for power in watts (W), PF is the power factor, I is the current in ampere (EIN), and VLL is the voltage between lines, das ist, the voltage between two phases.

2. Use line voltage (V LN) for calculation:

P= 3 × PF × I × V LN

In this formula, VLN is the line voltage, das ist, the voltage between the phase line and the neutral line.

It should be noted that the parameters in these two formulas have the same meaning as those in the single-phase AC formula, das ist, the definition and function of power factor PFPF, current II and voltage VV are consistent in the two calculation methods.
