As previously said, the amount of energy your air conditioner uses is determined by the amount of power it draws when running, as well as the length of time it operates.
Depending on the outside temperature, the average RV air conditioner requires 1-1.5 kWh of energy each hour. An RV air conditioner, for example, should use roughly 30kWh of electricity per day on a hot summer day if it’s turned on all day.
What is the power consumption of an RV air conditioner?
Air conditioners in modern RVs are infamous for being the biggest power hogs. When turned on, they can draw anything from 700 watts (for a 10,000 BTU unit) to 1,500 watts (for a 15,000 BTU unit). In fact, they can draw more than double that amount of electricity when they first turn on.
Consider one of the high-efficiency models listed here if you’re in the market for a new RV air conditioner. There are a number of advantages to doing so.
Run an Air Conditioner on Solar Power and Lithium Batteries
Yes. With the correct off-grid arrangement, it’s doable. In the past, this would have been considered insane. It’s now more frequent than you might believe. A high-efficiency air conditioner may run for several hours on an RV with a correctly sized battery bank, power inverter, and solar array.

After a full day of summer activities, returning to a sweltering RV can be a bit of a letdown. That’s why, even when you’re out and about, it’s typical to want to leave your air conditioner on. You might, however, ask if you can leave your air conditioner on all day.
It would not be a problem to run your RV’s air conditioning equipment 24 hours a day, seven days a week. You simply need to decrease your thermostat a few degrees so that your compressor can still cycle on and off and function properly. Most significantly, if you want to keep it going all day, you’ll need a sufficient source of power.
In a day, how much electricity does an RV consume?
A typical RVer uses roughly 20 kWh per day on average. This equates to around 608 kWh each month or 7,300 kWh per year. During the summer, usage will be lower, and during the winter and summer, usage will be higher.
An RV air conditioner consumes how many amp hours?
The usual RV air conditioner is rated at 13500 or 15000 BTUs, and they use between 1300 and 1600 Watts when they are running.
The average amount of battery energy required to run an RV air conditioner is between 90 and 130 Ah (amp-hours) per hour of operation. 2-3 100AH Lead-Acid batteries or 1-2 Lithium batteries can offer this amount of energy.
In other words, depending on the type of battery you use, you’ll need 1-3 12V batteries for every hour of use. The reason for this is that different battery chemistries have varied permissible discharge depths. (See below for more information)
Is it possible to use solar panels to power an RV’s air conditioner?
Yes, it is technically possible to use a solar panel to power an RV air conditioner. However, a huge number of solar panels and electrical infrastructure modifications are necessary to generate enough power. Another option is to use a “Soft Start” gadget. The great majority of RV owners are unlikely to go to such lengths. Continue reading if you’re willing to create a large enough system for RV solar panels to power an RV air conditioner.
What is the power consumption of a 15000 BTU air conditioner?
Mini-split air conditioners use less energy than window and portable air conditioners, therefore they need fewer watts and amps to provide the same cooling output. Mini-split AC units have an EER value of around 12 on average.
Mini-split air conditioners come in a variety of sizes: tiny (9,000 BTU), mid-range (24,000 BTU), and large multi-zone units with cooling outputs of up to 60,000 BTU (5 tons).
This table (with a projected 12 EER rating for all units) will help you figure out how many watts your tiny split AC unit uses:
Note about wattage and RV air conditioners: How much power do RV air conditioners consume? To run a 15,000 BTU RV air conditioner, you’ll need roughly 1,500 watts. However, it will require a start-up power of around 3,000 or possibly 3,500 watts.
You can calculate how much it costs to run an air conditioner by determining how many watts it consumes. That is, if you have a steady supply of electricity, which leads us to the next section:
Is it possible to run the air conditioner in my RV on battery power?
Yes, to put it succinctly. You can run your RV AC unit on batteries if you have the right equipment and enough batteries. In addition to the lithium batteries, most air conditioning equipment will require an inverter to convert DC battery power to AC power.
While many RV electrical components operate on 12 volt DC electricity, some larger appliances, such as an RV air conditioner, require AC power. Just to be clear about anything, the “Air conditioning” is represented by the letter “AC” in “AC unit.” The “AC” in “AC power” stands for “alternating current.” “Ancient current.”
12V air conditioners are becoming increasingly popular in smaller RVs. These are substantially more energy efficient and can easily be powered by batteries. Designed to order “Traditional RV air conditioners are substantially less efficient than mini-split” units. This more efficient custom design alternative is preferred by many customers who want to run their air conditioning on batteries.
You’ll also want to get a soft start kit or an EasyStart for 120V AC devices, in addition to an inverter. When your air conditioner initially turns on, it draws 4-8 times the amount of current required to run the compressor. This is referred to as “a surge of current” A soft start kit improves the AC compressor’s startup efficiency while also lowering the power drain on your batteries.
While it is possible to run your RV AC unit off of your batteries, there are a few things to consider. Due to the high power demands of an RV AC unit, even larger battery banks won’t be able to keep it running for long. This makes running them for long periods of time problematic.
Running your RV’s air conditioner on lead-acid batteries, on the other hand, was nearly impossible. The fact that it can be done using lithium batteries is a game changer in and of itself!
How long can an RV air conditioner be run on a generator?
You can run your RV’s air conditioner on a generator for 8 hours and use no more than 2 gallons of gas. Diesel generators use even less fuel than unleaded gas generators.
You can use a portable generator if you’re camping off the grid or don’t want to operate your air conditioner on power. Unlike using a 110 plug, portable generators allow you to power more than just the air conditioning.
Of course, the heavier the weight, the more fuel you’ll consume. So if you only want to operate the air conditioner, you won’t waste as much energy as if you also want to run the refrigerator, coffee maker, and television.
