Best 3 Indoor Generators for Backup Power: Safe, Clean and Quiet

What Is An Indoor Generator

Power outages have become an unfortunate reality of the modern world. But thanks to some best indoor generators, it's easy to power electrical appliances during rolling blackouts and brownouts. An indoor generator is a practical charging solution used at home that keeps your devices running during power outages.

Types of Generators

Whether you live in a house, apartment, or condo, it is crucial to have a dependable and safe energy supply. Some common types of generators for homes include the following:

  • Portable Solar Generators: Small, compact, and portable solar generators are typically fueled by solar energy. Their small size makes them easy to carry from one place to another for quick appliance charging. In addition, solar generators do not emit any harmful gases, making them ideal for closed spaces.
  • Standby Generators: They are a semi-permanent feature of the home that generally takes up more space than a standard air-conditioning unit. They have a large fuel tank that can supply electricity to home appliances in emergencies.
  • Gas Generators: Gasoline generators are popular charging solutions to power different types of appliances. However, they are highly flammable and produce emissions, which may pose safety risks.

Gas and solar generators are the two most popular solar solutions available to charge different types of appliances during short and long-term power outages. However, gas generators emit harmful gases, making them less suitable for indoor usage. Therefore, many homeowners are switching to solar-powered generators that are safe, clean, and quiet charging solutions.

In this article, we'll dig deep into the best indoor generators, what size generator will suit your needs, and how to choose the ideal one.

What Size Indoor Generator Do I Need?

Investing in a solar indoor generator for an emergency outage is inevitable, yet, most people find it to decide which is the right size generator for their needs. In simple words, the right-size solar generator is the one that can efficiently meet the electrical needs of your home by supplying clean energy.

But how to choose the ideal size indoor generator? To figure this out, you'll need to calculate the wattage of the appliances you want to use during blackouts with some extra power.

Before we understand the solar generator size or calculate it, it's essential to understand the general term "watts." The power output of the solar generator is measured in watts. The two power output figures that you must keep in mind when buying a generator include:

  • Starting Watts or Maximum Surge Power: It is the additional boost that the generator delivers for a short time to start high-power-consuming appliances. Most small appliances consume fewer starting watts, which can easily be ignored during calculation.
  • Running Watts or Continuous Power Rating: It is the amount of power consistently delivered by the solar generator. Your generator must be capable of supplying running watts for long hours for optimum operation.

For instance, a standard modern refrigerator generator requires nearly 1200 watts of power to start up. However, it draws only 200 watts of energy once for running. Since the refrigerator consumes starting watts for only a few minutes, you can easily ignore it during calculation.

Generally, the minimum wattage required for indoor use during a power outage is 2000 to 8000 watts. An indoor generator with a large battery capacity can power essential home appliances.

You must ensure the solar generator you buy is powerful enough to run all the appliances and start them up.

The below reveals the common indoor appliances with their starting and running watts. We will also discuss the essential watts required for 2 hours, 4 hours, 10 hours, and 24 hours.

While calculating the solar generator size for the home, remember that you don't have to run all the appliances at once. For example, you only need to use the stove when cooking. Similarly, you need a washing machine when doing laundry.

Additionally, appliances like refrigerators and freezers can be turned off for one or two hours without food spoiling. Considering these factors, you can understand that you don't need quite as large a solar generator as you think.
