            How To Choose The the Best Generator For RV Air Conditioners?

            Type of Fuel

            • Recreational vehicle AC runs off 110V AC through a generator, which is the reason it doesn’t operate on diesel or battery, but propane or gasoline.

            • While gasoline produces 125,000 BTUs/gallon, propane is a bit inferior - 91,500 BTUs/gallon. And gasoline is superior in terms of portability since propane generator will require a propane tank, which is a bit bulkier.

            • But propane lasts longer and is not as degrading as gasoline if irregularly used. Hence, if your choice is gasoline, I advise not to store it for too long in your house, RV, or garage.

            Type

            • Between conventional and inverter generators, I highly advise choosing the second type for RV ACs. Why?

            • Because differing from the conventional, inverter generators produce clean energy to be safe for sensitive appliances while being quieter, more compact, portable and fuel efficient.

            Size

            • Since air conditioners are constructed with higher needs of starting up wattages than to run, it’s essential to find out how many watts output for your electrical appliances.

            • According, there are three common generator sizes:


            Small (< 2000 watts)

            Medium (2500 – 3500 watts)

            Large (> 5000 watts)

            Specifications

            Price range: $500-$1000

            Total Weight: < 60 pounds

            Enough to power a 10,000 Air conditioner

            Total Weight: 80 – 160 pounds

            Price Range: < $1000

            Total Weight: 230 – 250 pounds

            Have a transfer switch

            Strength

            -lightweight & compact

            -quiet to run

            -relatively powerful to run a few large appliances at once

            The most powerful -> Can handle power needs of the largest RVs

            Affordable

            Weakness

            -don’t provide enough power for many large appliances to use at once.

            -relatively heavy

            Really heavy & difficult to lift in and out of your RV

            Use most fuel

            Solution

            Find a small generator with parallel functions

            Equip a pair of wheels or handles

            Buy an extra mount for RV that can carry a heavy, large generator

            Best for

            RV owners who don’t need a ton of power

            Mid-sized RVs

            Who live full-time in an RV and are boondocking at campgrounds

            • The size of your RV air conditioner will determine the generator’s size since this appliance consumes the most energy in an RV.

            • For example, if your AC requires 1500-2000 running watts, and 2800-3000 starting watts, a 3000W generator will be the best choice.

            • There might be some other large appliance needed operating, such as fridge (600W), microwave (1000W), television (120-200W) or radio (50-200W). In this case, a 5000W generator should be fine.

            • Count the maximum starting wattages of all needed appliances in your RV and choose the most suitable generator.

            Which Brands Make The the Best Generator For RV Air Conditioners?

            Champion

            • As its name defines, Champion is unbeatable in the generator industry. They are a long-standing company, well-known for the perfectionism in both the product’s performance and customer service. The price is also affordable.

            Briggs & Stratton

            • There are lots of compliments for Briggs & Stratton in terms of portability and lightness while keeping powerful energy output and runtime. In most cases, their products are utilized mostly in camping, tailgating and RV us.

            Westinghouse

            • Last up, is Westinghouse – the brand that’s renown for their product’s fuel efficiency, which is the reason that many pro campers or RV-ers prefer to use their generators. In long terms, they are economical to operate.

            FAQs

            Can I run my RV AC on 30 amp?

            Check if your RV AC has a 30 Amp system. If yes, rest assured you can run it on 30 Amp electric outlet. But if yours is built with a 50 Amp system, buy an extra adapter that inverts 50 Amp to 30 Amp.

            Which fuel type is best for RV air conditioner?

            This spec is different from model to model so, it’s better if you ask about the fuel type that your RV air conditioner should run on.

            Do you need an inverter generator for RV AC?
