Best Generac Inverter, Portable, and Home Standby Power Generators
Generac power generators range from small inverter generators being able to power just a few smaller home appliances to home standby units being able to power the entire home during the blackouts and to large, towed units being able to power even several homes or to provide energy even for larger construction sites.
Generac power generators are well-balanced units offering good performances at an acceptable price, but just like any other power generator, they must be also maintained properly in order to operate without issues.

Generac Inverter Power Generators
Generac inverter power generators are compact, portable, and relatively lightweight power generators.
These versatile units range from 1kW to ~3.5kW and are used whenever and wherever reliable power generators are required.
Thanks to advanced muffler design and fully enclosed construction, Generac inverter generators are some of the quietest units in their respective power classes, making them suitable for use in residential areas, for camping, tailgating, during blackouts and other emergencies and similar.
Efficient internal combustion engines, combined with high-tech inverter technology ensures long runtime on a single fuel tank and very low Total Harmonic Distortions (THD) ensuring that these units are suitable for powering even the very sensitive tools and appliances.
All those features do come at a certain price, but they are worth it.
And yes, there are cheaper units than Generac inverter power generators, but if You are looking for excellent quality and Honda power generators are kind of over your budget, go for Generac inverter generators.
Generac 7127 iQ3500 Portable Inverter Generator
Generac 7127 iQ3500 is a gas-powered inverter power generator powered by a 212cc OHV engine, providing 3000 Running Watts and 3500 Starting Watts. The engine features both electric and manual start.
The unit features a 2.6 gallons tank, which ensures runtime of 8.9h @50% load and 14.1h @25% load, using Eco Mode.
According to the Generac, Generac 7127 iQ3500 inverter power generator is 5 dB quieter than the Honda EU3000IS power generator.
Since Honda EU3000IS generates ~50 dB @25% load, that would be around 45 dB @25% load, which would be a fantastic result.
However, the Generac doesn't state the actual noise levels of the Generac 7127 iQ3500 power generator and we didn't have the opportunity to verify this claim - and no, measuring noise using a smartphone app is not a reliable method for measuring the noise of the power generators.
Nonetheless, Generac 7127 iQ3500 power generator is a surprisingly quiet unit.
Generac 7127 iQ3500 inverter generator provides output power with very low THD (<3%) making it safe for powering sensitive electronics and appliances.

Safety features include overload protection and low-oil automatic engine shut-off. Also, it comes with Hour Meter, Fuel Gauge, Wattage Meter, and the Run-Time Remaining displayed on its control panel.
The physical dimensions of the unit are 23.7 x 18 x 21.7 inches (60.2 x 45.7 x 55.1 cm) and it weighs 109 pounds (49.4 kg) dry - unit features a pair of carrying handles, allowing two adults to carry it to shorter distances and to load it on and off the truck, for example.
Generac 7127 iQ3500 comes with a 3-year residential and commercial warranty.
For people looking for a reliable power generator in the 2-3kW range, Generac 7127 iQ3500 is perhaps not the cheapest choice (and not the most expensive one!), but it is a quiet, fuel-efficient, and a rather versatile inverter power generator.

Few Final Words
Just like all other power generators, Generac power generators should be run only outside - during operation they release fumes that contain dangerous Carbon Monoxide (CO).
Also, when the new unit arrives, be sure to read the manual/Owner's Guide thoroughly and to get accustomed to your new power generator.
In the end, no matter how good the power generator is, if it is not maintained properly, it will fail sooner or later.
So, when your new Generac power generator arrives, regardless if it is an inverter generator, portable generator, or standby unit, be sure to read the documentation and to maintain the unit as recommended - in that case, it is highly possible that your Generac power generator will serve You well beyond its warranty period.
