A 10 KVA genset can run 2 AC units at the same time.

you can run 15000 btu split ac on 10kva generator

A 10 kVA generator will power a couple of standard air conditioning units, but not 10 at once. If you’re running an air conditioner in the home or office, getting a larger generator would be helpful. You can also plan ahead by purchasing several smaller generators so that you don’t get caught without adequate energy when the weather changes unexpectedly.

What can a 4 5kva generator power

First you need to know how many amps your AC will draw from the generator. All appliances have a rating called Voltage Amps Load, or VAR rating. This is expressed in amps and all other ratings are based on the VAR rating for that piece of equipment.

The amount of kVA or Kilovolt-Amperes that you need to run your air conditioner primarily depends on the make, model and age of your AC unit. Newer units tend to consume less power than older units, so you can go with a smaller generator if your AC is relatively new. The same goes for size / capacity of the AC unit itself – larger units typically use more electricity than smaller ones.

When you’re buying a generator, be sure to consider what it is that you want to run and how much wattage it requires. Examples of typical household appliances are: refrigerator: about 1 750 watts, microwave oven: about 1000 watts, washer and dryer combo: about 1500 watts, electric heater (not baseboard): about 2000 watts.

Why Do You Need a Generator for Your RV?
If you plan to spend most of your time camping in an RV park or campground, a generator won’t be of much use. However, if you want to camp away from the crowds in a more natural environment, you’ll need a generator.

When you’re camping in these environments, you’re not going to have the luxury of plugging your RV into a power pedestal as you would at a campground. You’ll need a way to create your own power, and a 30-amp RV generator is a great choice. They’re one of the most cost-effective means of getting power, and they’re typically extremely portable.

Even if you have a 50-amp RV, you can run almost everything in your RV with a 30-amp RV generator. You may need to manage your power, especially when running an air conditioner, but it’s still possible. Whether you just want to keep your battery bank charged or watch the big game on your TV, you can do it all while RVing off the grid with a generator.

What Size Generator Do I Need for a 30-Amp RV?
A 30-amp RV can use a maximum of 3,600 watts. There are some great 3,500-watt generators. However, this may require some power management, especially when running high-powered appliances like air conditioners, coffee makers, or instant pots.

Top 5 Regrets of Buying a Motorhome
However, if you don’t plan on using these high-powered appliances, you can get by with a much smaller generator. Some RVers use 2,000-watt generators because they don’t just produce smaller amounts of power, but they’re substantially smaller, quieter, and easier to move, too.

Pro Tip: Need more help deciding what generator is right for you? Here’s how to know what size generator you need for your RV.

How Do You Hook Up a Generator to a 30-Amp RV?
Many 30-amp RV generators will include a power connection for a 30-amp RV power cord. Turn the generator off while connecting your RV’s power cable to the generator. You can still use a surge protector to keep your RV safe.

Once connected, simply turn the generator on. As long as you have fuel in your generator, you’ll have the ability to charge your battery bank or run appliances. You’ll also have access to your power outlets for charging and plugging in electronics.

What to Look for in a 30-Amp RV Generator
If you’re shopping for a generator for your RV, there are a few things you should consider. Let’s take a look so you can get the best bang for your buck on your RV generator.

Size and Weight
Generators can be large and heavy, which makes them difficult to move. This is especially important to consider if you’re storing the generator in a location that will require you to move it to use it.

6 Walmart Boondocking Rules to Follow
Many of the 3,500-watt generators for RVs can weigh upwards of 100 lbs. This weight can make it a two-person job to maneuver it out of a vehicle or around the campsite. Make sure you’re capable of handling the size and weight of your generator.

Fuel Economy
You want a 30-amp RV generator that’s not going to be a fuel hog. If you’re burning through your fuel, you might need to make a trip to the nearest fuel station to resupply. This can be rather inconvenient and take away from your adventures.

The higher the load you’re putting on a generator, the more fuel it will consume. It’s similar to driving a vehicle. The more you push the accelerator, the more power the engine generates. The more power the engine generates, the harder it has to work, which uses more fuel. So if you’re using a 2,000-watt generator and constantly requiring 1,800 watts, you’ll be maxing out your generator and using a substantial amount of fuel.

Noise Level
Make sure your generator is quiet. If you’re camping in a location where you’ll need to use a generator as a power source, you don’t want to fall asleep to the hum of a generator.

There’s something special about sitting out in a remote area and listening to complete silence. You don’t want to ruin that experience with a noisy generator. You’re also more likely to make an enemy out of a neighbor, as they likely don’t want to listen to your generator any more than you do.

The Best 30-Amp Generators for RVs
While you may have a construction-grade generator lying around, you don’t want to use it while RVing. Inverter generators are great for RVing because they create much cleaner power and are quieter.

You don’t want a loud generator to ruin your camping adventures. So let’s take a look at five of the best inverter generators we think you should be considering!

What Size Generator Do I Need to Run My RV?
The size generator will be dependent on your RV and your power needs. If you’re looking to run an AC or two, you’ll need a larger 3,500+-watt generator. However, if you’re just looking to keep your batteries charged, you could get by with a 2,000-watt generator.

You may also benefit from modifying your high-powered appliances to help reduce their power draw. Installing a soft start on your ACs can allow you to run your ACs, but use substantially less power. Many RVers who regularly rely on a generator can run two AC units on 30-amp service. This can allow you to buy and carry a smaller generator for your adventures.

Is a 30-Amp RV Generator Worth It?
Depending on your preferred camping style, a 30-amp RV generator can pay for itself. You can save a ton of money by boondocking and camping on public lands.

However, the monetary gain is just the tip of the iceberg regarding the benefits of owning an RV generator. The freedom of comfortably using your RV outside of crowded campgrounds is priceless.

Champion 3400 Dual Fuel 30 Amp Inverter
Champion 3400 – the best inverter generator width dual fuel capacityThe Champion 3400 Dual Fuel inverter is one of my personal favorite generators.

It’s one of the only few inverter generators offering the choice of two fuels – gas and propane.

Switching fuels is very easy as all you need to do is push the fuel selector dial.

It is also fully RV ready as it comes with the dedicated 30 Amp RV outlet.

There is no need to purchase any additional accessories before you plug it to your travel trailer.

The generator produces the total power output of 3400 starting watts and 3060 running watts (when running on propane).

This is enough to run all the crucial appliances you need in your 30 Amp RV.

These include:

RV Air Conditioning Unit (as large as 15000 BTU)
RV Refrigerator & Freezer
The generator is very fuel-efficient. It can run for around 14 hours on gas and 7 hours on propane at 50% load which is a good result.

It’s an inverter generator working under the minimum recommended THD (Total Harmonic Distortion) threshold. That makes it ideal for running modern portable electronics.

This 30 amp RV generator comes with parallel capability. That means that you can get the optional parallel kit allowing you to connect two inverters together and maximize the total power you get.

Another strong selling point of this generator is its good price. It’s significantly cheaper than Honda generators.

When we take the price into account, the Champion 3400 is the one to grab the title of the best 30 amp generator.

Honda EU3000iS
If you ask most of the people experienced with portable generators about who makes the best generators out there, a lot of them will answer: Honda.

It’s true that Honda makes some of the strongest and most reliable gensets in the market. Their flagship inverter EU2000i, later succeeded by EU2200i became the synonym of the quality generator.

Honda EU3000iS is another superb quality generator made by Honda.

This 30 amp generator features the original Honda GX200 4-stroke engine – one of the best in the market.

It is one of the strongest inverter generators available. You could easily run a typical RV air conditioner and a few smaller items on top of it.

What I like about Honda Eu3000is is how quiet it is. At 50% load if produces only around 58 dB of noise which is REALLY silent for the generator of this size.

This is by far the quietest 30 amp generator I have ever found.

EU3000iS has got parallel capability. You can use the parallel kit (purchased separately) to connect two EU3000iS together and double your total power output.

The generator is very simple to use. Besides the manual recoil start, it also has an electric startup. You can turn it on and off with a simple push of a button.

This generator is overall a great and very reliable choice for those who look for the generator for home backup power supply, worksites or RV camping.

The only downsides include the high price tag (all in all it’s Honda…) and the lack of wheels and carrying frame in the kit – you need to purchase these separately.

In any case – this is one of the best 30 amp portable generators and the ideal choice if you need a very sturdy 30 amp inverter generator.

Check out my full review of EU3000is here if you want to learn more about it.

Champion 3800 Dual Fuel
When reading this roundup review you might suspect that we’re biased towards the dual fuel generators.

However, we’ve got plenty of reasons to like them more than many other generators we’ve reviewed.

First, the choice of two fuels is a massive convenience and can be a real game-changer during an emergency when the availability of fuel is key.

Second, it just happens that some of the best 30 amp generators we have researched are the dual-fuel models.

While they might cost a bit more then generators running on gas only, they are more cost-effective in the longer term. They are also more environmentally friendly.

Champion is one of the most recommended companies making these kinds of generators.

The Champion 3800 is a very solid open frame 30 amp generator ideal for a variety of situations.

You could use it to run equipment like an 11,500 BTU air conditioner, freezer, fridge, and lights.

The generator comes with a convenient electric start. Switching the generator on and off happens at a simple push of the button.

The generator has got a very long run time even when operating only on propane. You could expect it to run for up 10 hours depending on the load on a single propane bottle.

While I wouldn’t call this generator a loud one, it certainly is not as quiet as inverter gens. However, if you are looking for a generator for work or emergency home backup, the noise will not be your main concern.

Having said that, with its 69 decibels it’s still less noisy than many older 30 amp portable generators.

Overall this is a very solid gen made by a trusted company known for their good customer support. It’s also a very inexpensive gen selling for reasonable price online.

Frequently Asked Questions about 30 Amp Generators
How many watts is a 30 amp generator?
The generators with 30 Amp plugs usually produce more than 3000 starting watts of power.

What size generator for 30 amp RV do you recommend?
We’d advise getting a generator with a total power output of at least 3000 watts.

The generator this big would allow you to run the air conditioner and other equipment in your RV without any problems.

A 3000 watt inverter would be also compact enough to make it easy to transport. It would also burn less fuel and make less noise than larger generators.

Can I plug my RV into a generator?
If the generator has got a dedicated 30 Amp RV plug then yes – you can plug it directly to your RV using an extension cord.

Otherwise, you would need to purchase a special 30 Amp 3 prong adapter.

They are very easy to find and usually cost around only a few bucks on Amazon.

Will a 3500 watt generator run my RV?
Totally yes! 3500 watts is more than enough to power your RV, including the most important and energy-demanding appliances such as the AC.

Your total required wattage

Many people ask us “what size generator do I need?” The answer to this question depends on what it will be used for. All our models are rated to run at a certain wattage, so you must consider the amount of wattage you need your generator to produce. Regardless of whether you’ll be running camping equipment or a whole construction site, this is a vital step in the buying process – otherwise, you might end up with a generator that isn’t fit for purpose.

Here are four key things to consider when it comes to wattage:

  1. You can find the individual wattages of an item on the equipment itself, in the user manual, on a manufacturer’s website, or by contacting the manufacturer by phone.
  2. What items do you want to run together? For example, if you want to run a slow cooker and a fan at the same time, you need the combined wattage of the equipment. If you’ll only ever run each item independently, then you just need to worry about the item with the highest wattage.
  3. Do the items have a starting wattage? Any piece of equipment with an induction motor will have a starting wattage, and therefore a higher wattage requirement. This includes chop saws, air compressors, vacuum cleaners, pressure washers, and freezers – anything with a motor in it. Simply multiply the item’s wattage by three to find its starting wattage.
  4. Give yourself some headroom. Just because your car can go 120 miles an hour, doesn’t mean that it’s suitable to drive at the maximum all the time. Your generator will be very much the same; a 4200W generator shouldn’t be used to power 4200 watts worth of equipment. Give yourself at least 20% headroom.
