Best Generator for Well Pump

Buying Guide for Generator for Well Pump

You may notice, the generators of my top list have a pattern. I have listed different sizes of the generator for the Well pump. It is not hard to calculate the right size generator for your Well pump. You could follow this guide and you will get a clear concept about the Well pump and generator.

Power Rating of generator and Well pump

Usually, most of the Well pump comes with an HP rating. HP means Horsepower. This is an international unit for the pump. However, this is the key to identifying the size of the generator for your Well pump.

You will get the HP and voltage of the user manual or the body of the pump. Say, you have a 1HP Well pump that runs on a 240-volt line.

We know, 1HP = 746-watt. So, you need a double-powered generator that means (746*2) 1492-watt generator to start and run the Well pump with 100% efficiency.

The calculation is the same for the 1.5HP or 2HP well pump. If you want to run other appliances, just consider their wattage with this particular value.

Generator Type

There are different types of generators available in the market. according to the functionality, there are two types of generators you will find.

They are an inverter generator and an open frame generator. If you want to run a sensitive device like a mobile, Laptop you must need an inverter generator.

Actually, a Well pump is not a sensitive device. But if you are looking for a minimum noise and fuel efficiency option you could buy an inverter generator.

On the other hand, if the moderate noise is not an issue for you and doesn’t want to connect the Well pump with the standby generator, you could buy an open frame generator.

Quality of Generator

Generators are expensive. You should buy a long-lasting generator that comes with a sturdy frame as well as an engine. I would recommend you buy the close-frame generator. Yes, they are more expensive than the normal generator, but longevity matters.

If you have a tight budget you should consider at least a steel frame and rust resistance generator for your Well pump.

Fuel Type

Usually, Gasoline and Propane generators are popular across the USA for home and RV use. Gasoline is more flammable fuel than Propane. Moreover, Gasoline is good for the engine.

On the other hand, Propane is common in every household. But you will not get 100% efficiency of the engine with the Propane.

Anyway, I suggest you buy a dual fuel generator. They are awesome indeed. You will not regret it in the future.

Frequently Asked Questions

What Size Generator to Run Water Well?

The size of the generator depends on the pump actually. I have already discussed that you need at least two times more power than the Watt of your Well pump.
Say, you have a ½ HP pump. So, the watt of the pump is (746/2) = 373 watts. So, you need at least a 746-watt generator to run the pump with 100% efficiency.

Do I Need A Transfer Switch To Connect My Well Pump To The Generator?

If you connect the Well pump directly with the generator, you don’t need the Transfer switch. A power breaker is enough here. In most modern generators, a Power breaker is the default feature.
On the other hand, if the Well pump is connected with the Home backup line, you should use a transfer switch.

Can I Refill the Generator While It’s Running?

Never do this. Never refill your generator while running or it is hot. You know, Gasoline is a very flammable fuel. There is a high chance of an accident if you do that.
You should allow your generator for at least a few minutes whether it is a propane or gasoline generator when it is time to refill it.

Will A 4000 Watt Generator Run a Well Pump?

Yes, you could run a Well pump with a 4000-watt portable generator. You can run up to a 2 HP Well pump smoothly with a 4000-watt generator.

Will A 5000 Watt Generator Run a Well Pump?

Sure, apart from a 2HP Well pump, you could run other small appliances like a light with a 5000-watt portable generator smoothly.

Will A 3500 Watt Generator Run A Well Pump?

Yes, you could run a Well pump with a 3500-watt generator. But you can not run a 2HP Well pump with a 3500-watt generator. 3500-watt generator is perfect for 1HP and 1.5HP Well pumps.

Final Thoughts

Long story short, you have a variety of choices for your Well pump. If you are intended to run only the well pump with a generator, then you could go for an inverter generator. They are medium-powered and cost-efficient.

On the other hand, if you want to run your home appliances or use the generator for RV trips or camping besides running the Well pump, you could go for the high-powered portable generator.

All of the generators in this list are worthy. You will not surely regret it after buying it. Please share the article with other people if you find this helpful. Thanks for reading! Good luck!
