## The Ultimate Guide to Volts to Watts Conversion

When buying a solar generator or portable power station, you'll first come across two crucial electrical rating terms — watts and volts. Calculating watts of specific home appliances will help you select a solar generator that generates appropriate power output to keep devices running for long hours.

However, sometimes the power output is given in volts. That's where volts to watts conversion comes in. If you know the volts of an appliance, you can quickly convert them to watts using the formula: P = V × I.

Jackery Solar Generators come in different sizes to meet all the power needs of customers. For instance, if you want a solar generator for off-grid living, you can consider Jackery Solar Generator 2000 Pro. Whether you're a homesteader, an off-grid adventurer, or just want a reliable backup power source, this ultimate guide will help you make sense of the numbers and choose the right size solar generator.

## Volts To Watts

Volts to watts conversion is necessary as it helps you understand how much power an electrical device or appliance consumes. Once you know the wattage of all the home electrical appliances, you can combine them to find the right size of inverter.

Volt is the unit of measure of the electric force responsible for the flow of an electric circuit. One volt is the amount of pressure/force required to flow one ampere current against one ohm of resistance.

On the other hand, watt measures the amount of power consumed by any electrical appliance. It also helps you select a power generator that meets your energy needs. Below we have explained volts and watts and why these electrical ratings are essential in solar power.

### What Is Volt?

A volt is a measure of voltage and represents the potential difference between two points of a conducting wire. It is the speed of electrons when they pass through a specific location in a circuit. One volt is equal to 0.001 kilowatts (kW) or 1000 watts (W) per hour.

If you know the voltage of a device, you can quickly determine the amount of current it draws. Calculating the watts of an appliance will help you figure out how much power will be drawn through any circuit by plugging it into a charging device.

In the solar power system, the solar panels generate electrical energy that can be measured in volts. Understanding volts helps you find a compatible solar system that will charge all appliances efficiently.

### What Is A Watt?

Wattage, in simple words, is the rate of energy used by a device. The unit of power helps us determine how much energy is needed to perform work or generate heat. One watt is equivalent to one joule per second, where a joule indicates a measure of power.

The power output of the solar panels is measured in watts. It represents the maximum amount of energy it can generally produce under ideal conditions, such as when the sun shines directly on the panel at peak intensity.

You can calculate the total power output of a solar power system from the number and size of the solar panels and the amount of peak solar energy that is available.

### Why Are Electrical Ratings Important In Solar Power?

Electrical ratings, including current, voltage and power, are essential when determining the right solar-based system. You'll need to consider the electrical ratings of solar panels, inverters, and battery storage to identify which generator meets your power needs and can deliver power for long hours.

The three electrical ratings – volts, amps, and watts – are interrelated. For instance, if you've two of them, you can easily find the third one using a simple formula or with a watts to volts calculator.

## How To Convert Volts To Watts?

Now that you know what watts and volts are, it's time to understand how to convert them.

Simply put, you can use Watt's Law to convert volts to watts. The law states current is equivalent to the power generated divided by the voltage.

The simple formula to convert volts to watts include:

P (Watts) = A (Ampere) × V (Volts)

Where,

P = Power

A = Current in amps

V = Voltage

### Volts To Watts Conversion Formula

Below we have mentioned some simple formulas that will help you convert volts to watts.

Formula 1: To Convert DC Volts to Watts

The power of an electrical device is equal to voltage times the current if it is a DC circuit.

P (in Watts) = V (in Volts) × I (in Ampere)

Formula 2: To Convert AC Single Phase Volts to Watts

The power is equal to PF (power factor) times the RMS voltage times the phase current in the ampere.

P (in Watts) = PF × I (in Amps) × V (in Volts)

Formula 3: To Convert Volts to Watts using Resistance

Sometimes, you know the resistance of the circuit but not the ampere value. In this case, you can use the below-mentioned formula to convert volts to watts.

P (in Watts) = (V)² ÷ R (in Ohm)

### Volts To Watts Conversion Examples

Let us take three simple examples to help you understand how to use these conversion formulas.

Formula 1: P (in Watts) = V (in Volts) × I (in Ampere)

Example: Suppose you need to convert 120 volts to watts for a DC circuit having 2 amperes of current.

P = 120 V × 2 A = 240 Watts.

So, 120 volts will consume approximately 240 watts of power, given that the amp is 2A.

Formula 2: P (in Watts) = PF × I (in Amps) × V (in Volts)

Example: Suppose you want to convert 240 volts to watts for an AC electric circuit having 10 amps of current and a power factor of 0.9.

P = 240 V × 10 A × 0.9 = 2,160 watts.

So, 240 volts will consume 2,160 watts of power, given that PF is 0.9 and amps are 10.

Formula 3: P (in Watts) = (V)² ÷ R (in Ohms)

Example: Suppose you want to convert 12 volts to watts for a DC circuit having 6 ohms of resistance.

P = (12V)² ÷ 6 Ω = 144 V² ÷ 6 Ω = 24 Watts.

## How To Convert Watts To Volts?

Like volt to watt conversion, you can convert watts to volts using the Watt's Law power formula. It states that current is equal to power divided by voltage.
Here is the mathematical representation of the conversion:
V (in Volts) = P (in Watts) ÷ I (in Ampere)
Where,
V = Voltage
P = Power
A = Current in amps

### Watts To Volts Conversion Formulas

To calculate the volts, here are a few simple formulas.
Formula 1: To Convert DC Watts to Volts
The voltage of the electrical device is equal to the power in watts divided by the circuit's current in amperes.
V (in Volts) = P (in Watts) ÷ I (in Ampere)
Formula 2: To Convert Watts to Volts in an AC Circuit
Unlike DC circuits, you'll need to consider the AC circuit's power factor (PF) during conversion.
V (in Volts) = P (in Watts) ÷ [I (in Amps) × PF]
Formula 3: To Convert Watts to Volts using Resistance
If the resistance of the circuit is known, you can easily convert watts to volts using the below-mentioned formula.
V (in Volts) = √[P (in watts) × R (in Ohms)]

### Watts To Volts Conversion Examples

Different formulas to convert watts to volts can be applied in different scenarios. For instance, if you know the resistance, you can use formula 3. Alternatively, if you know the ampere, you can choose the formula 1 or 2 depending upon the type of current.
Formula 1: V (in Volts) = P (in Watts) ÷ I (in Ampere)
Example: Suppose you want to convert 30 watts to volts using a DC circuit with 5 amps of current.
V (in Volts) = 30 watts ÷ 5 amps = 6 volts.
Formula 2: V (in Volts) = P (in Watts) ÷ [I (in Amps) × PF]
Example: Suppose for an AC circuit with a power factor of 0.9 and 12 amps, you want to convert 1400 watts into volts.
V (in Volts) = 1400 ÷ [12 × 0.9] = 129.6 volts.
Formula 3: V (in Volts) = √[P (in watts) × R (in Ohms)]
Example: If the resistance of the circuit is 20, you can convert 125 watts into volts using this simple formula.
V (in Volts) = √(125 W × 20 Ω) = √2500 = 50 volts.
