What Size Solar Generator Do I Need For My AC?

In California, from May 31 to September 16, the average daily temperature sits above 78°F, while the hottest month of the year is July. During this month you could expect temperatures with an average high of 86°F and low of 71°F.

While in Jacksonville Florida, the highest temperature recorded in 2021 was 108°F.

Why are we telling you this? 

Well, we are demonstrating just how hot it can get in the U.S., particularly in states like California, Texas and Florida. 

It is for this reason that air conditioners have long been one of the most popular appliances in homes and RV's alike. 

In this article we aim to talk about AC power consumption and what size solar generator you would need to power one.

How Much Energy Does An AC Consume? 

This all comes down to the model of AC you decide to buy. All you need to work out the energy consumption of your air conditioner is the power rating, and the amount of time you plan to use the appliance for. 

So for example, let's assume you buy a mid-sized AC unit, this is likely to consume on average 1000 watts. However, it does all come down to the size and type of unit you get. 

Another unit of measurement you should look at is the BTU rating. 

The BTU rating is the measurement of an AC's cooling capacity, that capacity can also give you an idea of how many watts it consumes:

How To Calculate Your Energy Requirements

Now that we have some understanding on how many watts an air conditioner consumes, we can use a simple formula to work out what size solar generator we would need to power it. 

Best Solar Generators To Power An Air Conditioner

The best solar generators for air conditioners are the following: 

• AC300
• EP500 Pro
• AC500

Let's assume that we purchase a 1000 watt AC unit. Remember it's true running wattage will be lower, due to the fact that the appliance cycles on and off throughout the day.
