What size generator would power a house?

table of contents

The generator can provide emergency power when the main power supply is cut off. It does not necessarily have to provide electricity to all electrical appliances in the house, it only needs to supply electricity to some basic household appliances. Such as lighting, TV, refrigerator, etc. Electric appliances such as electric stoves, air conditioners, and tumble dryers require too much electricity, and generally portable generators cannot meet the demand.

There are different generators on the market. There is a wide range of sizes, prices, and models available.  How to choose the right generator for your home? Discover our top tips for selecting the perfect generator for your home. Make a well-informed decision to ensure you receive superior quality at the best possible price, ultimately providing excellent value for your investment.

Some key considerations when purchasing a generator.

Power outage frequency

The first thing to consider is the frequency and duration of power outages in your area. If you live in an area with frequent power outages, you may need a more powerful generator. This ensures you have enough power to keep important equipment running smoothly until power is restored.

Watt

Another important factor to consider is the wattage requirements of your home appliances and equipment. Different appliances have different power needs, and it's critical to choose a generator that can handle the total wattage load of the necessities.

To determine wattage requirements, make a list of all appliances and devices that you expect to be powered during an outage. Look for its power rating, which can usually be found on the device itself or in the user manual. Add the wattage of all items to estimate the total power required.

What size do I need to power the house?

Determine the basic appliances that must be used at home. Please calculate the total wattage of the projects you want to run at the same time. For example, the power of a common microwave oven is 1500 watts, while the entire lighting circuit using energy-saving lamps may only require 150 watts. The refrigerator is about 1200-1500 watts, but there is a starting capacitor that instantly increases the wattage when the compressor starts. The TV is less than 1000 watts, depending on the type and size, a small household fan maybe about 500 watts and so on. A gasoline generator with a rated power of approximately 3,500 watts can provide electricity for lighting, televisions, electric fans, and refrigerators or freezers.

Considering the impact of the generator's full load for a long time on its performance, it is recommended that you choose a more powerful generator. An average-sized household needs 5,000 to 7,000 watts to power basic items.

But please note that if you want to run a laptop, flat-screen TV or any other type of modern electronic products. BISON recommends that you purchase an inverter generator. This is because traditional heavy-duty generators usually suffer from higher total harmonic distortion (THD).

Why is it important to choose right size generator?

First, an undersized generator may not be able to meet the power needs of essential equipment, leading to potential damage or failure. On the other hand, an oversized generator may consume more fuel than needed and result in unnecessary expenses.

Additionally, a properly sized generator ensures you peace of mind during a power outage. It allows you to maintain the comfort and functionality of your home, powering essential appliances such as refrigerators, lights, heating systems and communications equipment.

In summary, when purchasing a generator for your home, you must consider factors such as frequency of outages, wattage requirements, and the appropriate size needed to power your home. By understanding these considerations, you can make an informed decision and choose the right generator to keep your home running smoothly during a power outage.
