  • There is enough power to run the majority of sump pumps.
  • It is easy to transport
  • Very quiet
  • It can be paired by an additional unit.

  • Cap of tank. & fuel type: 1.06 gal. gasoline
  • Noise level: Not published
  • Starter: Recoil
  • Weight: 59.5 lbs.

This Generac Inverter Generator GP3000i is the ideal replacement for sump pumps that have greater initial currents. It is equipped with PowerRush Advanced technology that allows it to deliver up 3000W of surge power. Ensure that your pumps are running exactly as they should.

The disadvantage is that it burns up fuel much faster than the Rainier with just 5.8 hours for each refill. To compensate for that, it's extremely quiet, despite its power. Even though Generac does not publish their dB ratings however, the closed frame design will be obvious.

  • Pros
  • High surge capacity
  • Great for larger sump pumps
  • Also very quiet
  • Light and compact
  • Cons
  • Utilizes fuel at a faster rate than the Rainier unit.

4. DuroStar DS4000S

  • Cap for tank. & fuel type: 3.96 gal. gasoline
  • Noise level: 69 dBA
  • Starter: Recoil
  • Weight: 105 lbs.

If you're looking to operate your pump in the same way as it's used to be, this standard generator, which is non-inverter, is the one for those who want to do it the traditional way. It's capable of providing up to 3300W of continuous power and 4000W at peak power. This is enough power to power an appliance like a refrigerator, a pump and possibly a few other appliances.

Noise levels sit 69 dBa , which is on the same level as other generators with the same capacity. However, when it comes to cost-to-performance ratios it's hard to beat.

  • Pros
  • Very inexpensive
  • Great durability
  • High power capacity
  • Cons
  • Uses fuel fast

Installation reminders

Remember that when using engines, it releases dangerous substances that are harmful in large quantities. The most basic safety rule is to utilize it in a non-closed area at about 20 feet from your house with the exhaust in the direction of your home.

Buyer's Guide

1. How do you determine the right size sump pump's generator?

Only way you can know for certain that a generator is able to run the pump is to verify the current power rating of the pump. It's typically located on the nameplate located at the top or the side on the side of the pump. If you are aware of the model of your pump you can find it on the web.

Let's say that your pump is operating and the current at start is 20A and 8A respectively. Add each one of them to 110V and you get 880W (running) and 2200W (peak) as a result. You must find the generator above that is rated to handle the load.

2. Generators are of various types

There are two main types of technology that are used in generators today that are inverter and conventional. The traditional generators are usually more affordable and are offered in bigger dimensions. The issue is that they use more fuel as they aren't able to adjust the engine's speed to accommodate smaller loads.

Inverter models solve this problem by slowing down engines electronically, generating enough power to meet the requirements. This means you will have more time between refills, and less time to fret.

Inverter types are also typically made of closed frame construction, which allows it to be as silent as 50 decibels -- an enormous difference from the 60+ dBa typical models.

3. Fuel type

Portable generators are typically driven by gas. There arehowever certain models that operate using propane and gasoline to give you more flexibility.

Propane burns more efficiently than gasoline, which extends the life of your engine. It is also less expensive per liter, however it has an energy density that is lower as compared to gasoline. It means that the engine won't attain similar power levels.

What are alternatives to making use of generators?

If you're looking to know how to safeguard your basement during power interruptions without the use of generators, there are three alternatives. Explore our articles on sump pumps that are powered by water, battery backup sump pumps and energy inverters to know more about.
