Shopping Tips: Best 8000 watt Generators

For further information, we’ve put together a complete buying guide, which you can see here. Here’s the best list of what you should be looking for:

  • Is it possible to run an 8000-watt generator for a long time? In the long-lasting run, you can consider generator fuel injection for improved fuel efficiency and fewer maintenance hassles. Moreover, the total harmonic distortion (THD) should be less than 6% for long time use. 
  • Is noise a consideration? Well, when you go to buy a generator, always consider its noise level. The noisier the (94+db) generator, the more it will irritate. So pick a less noisy generator like Firman P08003.

User-Friendly

You should choose a top-rated generator that is easy to use and has automatic control choices that prevent your generator from deteriorating. Check for a low-oil “shut-off” function, which switches the engine off when the oil level drops dangerously low.

Easy to Move

The weight of a generator is not always related to the amount of power. More efficient generators are typically heavier. Thus, the presence of grips & wheels makes moving all of these generators much easier.

The Number of Outlets

Needless to say, a model with many outlets allows you to maximize the generator’s efficiency by dispersing the load. However, using all outlets is not suggested since it burdens your generator and jeopardizes its longevity.

Time to Run the Fuel Tank

The run-time of generators is usually specified as half (50%) or quarter (25%) of the load. It indicates how long this will operate at a certain percentage of the overall capacity on a full fuel tank. 

In addition, suppose you want to use your generator for emergencies and don’t know how much longer the power source will be out. In that case, you should get a generator with a larger fuel tank.

Final words

In short, if you’re considering putting a generator in your house as one of your emergency tools, then you can certainly go for the best 8000 watt inverter generators. Because they are generally small enough to be portable), it is easy to get them into the room; you need to use them anywhere in your house.

An 8,000-watt generator can power almost everything in your house. Moreover, that includes your fridge, oven, espresso machine, tv, lights, and sometimes even your stove. Most 8000 watt generators work well when used as a partial home backup generator and running essential appliances.
