About Generac Power Systems

However, if you haven’t used a generator before, we’d say that it’s plenty to get started. Its running wattage is 100 watts less than its direct competitor. However, we’re very nit-picky here as it’s only a minor difference. There isn’t an electric start. Instead, it’s manual recoil only. There is no data center. The Generac 5940 GP6500 portable generator gives you a lot of power to pull on two wheels.

CSA-approved and CARB compliant, this durable and safe generator is great for your larger power needs. When you need more wattage but prefer the convenience of portability, it can be tough to know where to turn. This Generac model gives you both of those features in one with their 5940 GP6500 product. With 6500 running watts and 8000 starting watts, this gas-powered machine sure does deliver. A convenient handle along with two sturdy wheels lets you take this model anywhere to use at home, on the job site, or during a sizable event.

What size Generac generator do I need?

  1. The 389cc OHV engine is built for the long-term, displaying consistent and reliable power over long periods of time.
  2. With solid construction and durability, you’ll get a lot of use out of this product.
  3. The fuel tank holds 7.2 gallons of gas, which lends 10 hours of run time at a 50% load.

Many consumers frequently asked common questions about products like the ones we have just discussed. Not all users of Generac generators are experts, so a little help can be a good thing. If you’ve read through our review and find that you still have some unanswered questions, take a look at this FAQ section; you might find the answers you’re looking for! Quiet is a bit of a relative term when it comes to generators. Truthfully, no generator is going to be 100% silent since you are essentially running an engine designed to power multiple other machines.

The noise level will be specific to your machine, and its features. Generally, a larger machine tends to produce more noise. A smaller generator (like an inverter generator) will be quieter. Also Read:Generac IX2000 vs IQ2000 Generator Comparison. Generac companies function out of the United States and Canada, apart from the United States they do service countries internationally. The answer to this question depends on what you plan on using your generator for.
