Generac generators review

Review on Generac generators

Generac is the leading manufacturer of affordable backup generators. The company was established in 1959. Generac has introduced a broad range of generators for commercial and industrial use. Around 40 varieties of residential generators from Generac can run either on natural gas or propane. These models can directly deliver the backup power to the electrical panel without any extension cord. A single generator can produce power up to 2 megawatts, which can automatically turn on during a blackout day. Since these generators are parallel compatible, they can provide additional power to industries if needed. The Generac generator has a remote monitoring facility that helps you monitor the generator’s status via your smart devices like mobile phones, laptops, etc.

Reasons to choose Generac generators.

The Generac generators gained positive feedback from customers within a short period. The running hours depend on the fuel tank size. Large fuel capacity generators can supply power for many hours. Some of the great features of Generac generators.

1. The Generac generators have a custom OHVI( Over Head Valve Industrial ) engine, which increases the generator’s durability. So if you are looking for a long-lasting generator, the Generac generators will not disappoint you. Besides, these generators cThe Generac generators gained positive feedback from customers within a short period. The running hours depend on the fuel tank size. Large fuel capacity generators can supply power for many hours. Some of the great features of Generac generators.

2. an produce power up to 2 MW. The engine’s pressurized lubrication increases the generator’s life.

3. These Generac generators are enclosed either with steel or aluminum. You can pick your color from a broad range of options. You can choose the generator according to your power requirements for running virtual devices at home or office.

4. Generac generators are designed to make less noise. The G-Flex technology employed in this generator is the biggest plus. This technology can make the engine self-adjust according to the amount of power required. This helps to save fuel to a great extent.

5.The Generac generators have a large variety of fuel options. The dual-fuel technology helps you to use both natural gas and propane, thereby lowering the carbon emissions.

6. The cost of a Generac generator is around $1500 approximately for indoor use. Depending on the features, the price may vary.

7. Durability depends on maintenance. It is recommended to stop the generator operation every 24 hours to check the fuel and oil level and remove the debris deposited inside the unit. Check to avoid water intrusion. Every 24 months, replace the engine oil.

Generac Generator vs. Kohler Generator

Engine: The manufacturers of Generac and Kohler generators have their own designed engines that run in any environment. Generac generators are dual-fuel generators, whereas the Kohler generator requires a conversion kit if any fuels other than gasoline are used. When a tri-fuel conversion kit is used, the Kohler generator can run on all three fuels ( gasoline, propane, or natural gas).

Impacts on the environment: Many fuel options help you use clean fuel for running both Generac and Kohler generators. The additional features like G-Flex technology in Generac generators will adjust the running hours according to the power demands, thus lowering carbon emissions. Kohler generators do not support this type of technology.

Noise Level: Both generators are quiet in operation. But Generac generators provide decibel ratings by undergoing a silent test mode weekly. The quick test mode is a test cycle that allows the generator to run at two-third of its average RPM, thereby maintaining a low noise level throughout the test. This function is absent in Kohler generators.

Enclosure Design: The Generac and Kohler generators provide their best exterior design to ensure safety. Kohler manufacturers provide generators coated with aluminum or steel, whereas the Generac generators have steel coated enclosures.

Types of Generac generators

Generally, Generac generators are classified into Portable Generators and Inverter Generators. Let’s discuss the top 3 generators in each category.

Portable generators

There are several types of portable generators for emergency backup. Generac has designed the best models with different features suitable for tailgating. Let’s have a look at the three best models of portable generators.

1.GP 5500 Generac generator

This generator can produce an output power of 5500 watts. An engine with 383cc OHV can deliver consistent power and increase durability. The fuel capacity is 7.2 gallons and can run the generator continuously for 10 hours at a rated 50% of the applied load. This generator weighs around 180 pounds. The additional features like automatic Low-oil shutdown, hour meter, and circuit breakers are provided for safety. The engine will seize when low oil is detected. The running hours of the generator can be monitored using an hour meter. The wheels and handles are provided for increased portability.
