If you are wondering how to solve problems involving Generator Power then you have come the right place as we have come up with a wonderful tool Generator Power Calculator. Simply enter the inputs in the allotted sections of the Generator Power Calculator and click on the calculate button to get output total current, supply voltage in seconds.
Using current readings from various equipment and appliances as well as the building's power supply voltage, the generator power calculator calculates the required power. In this article, we will discuss the power generator, the working principle of the power generator, and how to utilize a generator to power a house.
An electrical power generator (also known as a generator) turns the chemical energy of fuel like gasoline or diesel into electrical power. A detailed conversion would be from chemical energy to thermal energy, from thermal energy to mechanical work, and from mechanical work to electrical power.
Here are the calculations we used in our calculator now that you know what a power generator is and how it powers a house:
Power Supply Type |
Single-phase |
Three-phase |
Direct current |
Apparent Power (kVA) |
V * I / 1000 |
1.732 * V * I / 1000 |
------- |
Power (Kilowatts) |
V * I * PF / 1000 |
1.732 * V * I * PF / 1000 |
V * I / 1000 |
Motor Output Horsepower (HP) |
V * I * PF * η / 746 |
1.732 * V * I * PF * η / 746 |
V * I * η / 746 |
Generators can be used to power appliances in two different ways:
According to the generator power calculator, apparent power (kVA) is derived by combining the total current of the devices in amperes (A) with the supply voltage rating in volts (V), and actual power (kVA) is determined by using the power factor.
Additionally, the motor's efficiency and the calculated power can be used to calculate the motor's available horsepower.
You can use our generator power calculator to perform the following operations:
For a three-phase power setup, you can also find out the kVA requirement and amperage required for your generator. In addition to volt, amp, and power factor, there are two types of electricity you can choose from single-phase and three-phase power. When a power outage occurs, you can calculate how much power your company will need using a generator load calculator.

1. What Size Generator Do I Need to Power a House?
With a generator rated from 5,000 to 7,500 watts, you can power even the most critical household equipment, including the refrigerator, well pump, freezer, and lighting circuits. A 7500-watt generator can power all of these devices simultaneously.
2. What is the power of a 3.5 kVA generator?
A 3,500-watt (3.5KvA) generator may power a variety of household equipment, including refrigerators, microwaves, electric furnaces, and televisions.
3. Is it possible to use a surge protector with a generator?
A surge protector can be used with a generator. If you fear a surge from your generator would damage your home's appliances and electrical equipment, the only way to prevent them is to install a surge protector. A normal 120V outlet is included with most generators.
