What Size Generator to Run a House (with Chart)

Sudden power outages due to natural calamities can cause a lot of inconveniences, especially when no power source is available. A solar generator is a highly versatile and convenient power source for homes.

Think of it as a solar power source that can charge all home appliances, from electric kettles to large refrigerators. However, different solar power station sizes are available on the market, making it challenging to make an informed choice.

Before investing money into one, you need to ask yourself, what size generator to run a house? In addition, you need to understand which appliances you need to power daily.

This article will help our readers figure out what solar generator size will suit their power needs, how to calculate it, and which solar power generator they should buy.

What Is a Solar Generator For a House?

Before we calculate the right size of solar generator for homes, let us understand the mechanism of a solar power generator.

Solar generators come with solar panels that collect the magnificent sun's energy and convert it into DC (or direct current). The generated current charges the battery or power station so you can access the power even after the sun is down.

As direct current cannot power up the appliances, the solar generator consists of another component called a power inverter. It transforms the direct current into an altering current so you can use that power to charge all your gears.

A reliable, clean, and efficient power source ensures you are never powerless during power outages or outdoor adventures.

What Size Generator Do I Need For My House?

Determining the right generator size depends heavily on which appliances you need it for. You can use the power generated by the solar generator to recharge different appliances and electronics, which will determine which solar generator you should invest in.

For example, many people buy solar generators during power outages to power their small electronic devices like laptops, electric kettles, etc. They can choose a small 1000W solar generator. Meanwhile, people wanting to charge all their appliances can choose a 1500W-3000W power station.

Jackery solar generators come in different sizes that help you recharge lights, electric stoves, and everything in between. The top models available are Jackery Solar Generator 1000W, 1500W, 2000W and 3000W.

“We needed a generator back up that was easy set up, provide enough power to plug in our refrigerator, tv lights, coffee pot. ( these were our Priority) . We purchased the Jackery 2000 Pro with 2 solar panels, as we age, finding simplicity works best,and did not want to mess with gas generator, With pull start up, leaving outside, loudness, etc. This Jackery fit our bill with more power and longevity than we ever imagined. Living in Florida, we just experienced Hurricane Ian and Nicole, it certainly gave us peace of mind when power went out, and used inside house with no problems at all. Did above and beyond what the developer writes.I normally don't write reviews but had to share with the public to let you know "you will not be disappointed with Jackery 2000 Pro!" It lasted so long, that we did not even use the solar, but will follow up with another review when we test it out. Some say it may be a little pricey, but you get what you pay for,and this is well worth it! Wanted to drop in a picture off it, but camera decided not to cooperate right now." --Dee Verified

what size generator to run a house- jackery customer review

“We charged it up, testing both the solar panels and then adding in-home AC power. It took less than 2 hours. I then used the generator to power my chest freezer for a while to make sure it could do it. Then during the next hurricane, I hooked my sump pump to it and it did well. It is a bit too heavy for me (an older, not too athletic woman) to carry, but the guys seem to have no trouble.” --LLMommyM

Understanding Starting, Running Wattage For Appliances

Power stations or solar generators are sized in watts (W). The higher a solar generator's watt, the more power it can generate and the more appliances it can charge. The two standard terms associated with watt calculation are starting watts and running watts.

Starting watts is the amount of power or energy appliances need to start up. Meanwhile, running watts is the energy any device needs to run after initial startup.

Generally, running watts is much less than starting watts. Understanding the wattage requirements of various electric appliances will help you calculate the power needs of the generator.

Here is a simple example of calculating the generator size yourself.

Suppose you want a generator that can power up a large refrigerator. It needs a burst of power to get started, termed starting watts. But the amount of watts it requires to run consistently is called running watts.

Let's say it needs 400W running power or wattage to function. That said, you need to choose a solar power generator capable of providing constant charge to the appliance.

Here is some simple mathematics.

  • Running wattage, R = 400W
  • Starting wattage, S = 400*3 = 1200W

The total wattage you need to run your large refrigerator would be around 1200W. Therefore, you should buy a generator capable of supplying 1200W and above to keep your appliance running for hours.

Similarly, you can calculate the running, starting, and total wattage of all your home appliances to get an answer to "what size generator do I need for my house."

Why Do You Need a Solar Generator For House?

Preparing your home with an efficient and reliable power source is becoming more than necessary. With power outages and blackouts becoming common, keeping a power backup solution for the home is ideal. Until recently, fossil fuel or gas generators were the go-to choices for people. But today, people realize the immense benefits of solar power generators. Some other advantages of solar generators include the following:

  • Reliable and Renewable Energy

Solar generators are a reliable and renewable energy source compared to other power alternatives. The solar panels arranged beneath the sun will store the solar energy and convert it into electrical energy. As no artificial elements are involved in energy production, it adds up to help you access natural and reliable power.

  • Safe to Use at Home

Advanced solar generators like Jackery products feature a first-rate lithium battery that houses two chips for dual protection. In addition, four core detectors ensure an appropriate amount of charge flows to and from the solar generator.

The in-built Battery Management System (BMS)™ protects the circuit, guaranteeing that the generator is safe to use at home.

  • No Fumes, No Need to Use Fuel

Solar generators use solar energy rather than fuel to recharge and power home appliances. That said, no fumes are produced, guaranteeing clean energy at home. To charge the home appliances with a solar power generator, you need to connect the explorer with solar panels and let it recharge its battery.

  • Saves Money and the Environment

Monthly electricity bills can dread you. However, that's not the case when you have a solar generator at home. Once you know the answer to "what size generator do I need for my house," you can reduce the high electricity bills. Not only does solar energy help you cut down the high bills, but it also ensures that you cause no harm to the environment by producing toxic carbon emissions.

  • Easy to Use and No Maintenance

Unlike gas or fuel generators, solar generators are extremely easy to use and require no maintenance. You can dust off the solar generator with a clean cloth to ensure it runs efficiently. The press-and-play feature of Jackery Solar Generator 2000 Pro provides that anyone can operate it with a single button press. In addition, it features a battery-level monitoring system and fault code indicators that make it user-friendly.
