generac 7043 home standby generator


If you live in an area prone to power outages, investing in a standby generator can be a lifesaver. One of the most popular options on the market is the Generac 7043 Home Standby Generator. As an experienced reviewer, I have been testing this generator for a while now and am ready to share my insights.

Build and Design

The Generac 7043 Home Standby Generator is built to last. Its dimensions are 48 x 25 x 29 inches, and it weighs 500 pounds, which is pretty standard for this kind of generator. The enclosure is made of aluminum and features a powder-coated finish, which gives it a sleek look that can blend into any backyard decor. Additionally, the enclosure is waterproof, ensuring that the generator remains safe during storms and other extreme weather conditions.

Power Output

This generator provides 22,000 watts of power, which is sufficient to power an average-sized home. The generator operates on natural gas or propane, and its fuel capacity is 722 cubic feet per hour or 160 gallons for propane. It also provides 22,000 running watts and 26,000 starting watts. This is enough power to run critical appliances like air conditioning units and refrigerators.


One feature that stands out is the automatic transfer switch, which can detect a power outage and turn on the generator within seconds. This is especially useful if you’re not at home during an outage. Additionally, the generator has LED indicators that display maintenance alerts, low fuel warnings, and other important information. The generator is mobile link compatible, which means that you can monitor it remotely from your smartphone. Additionally, this generator is designed with safety in mind, with features like a low oil shutdown and an automatic voltage regulator.

Installation and Maintenance

While installation can be tricky for people without electrical experience, the installation process is pretty straightforward. If you don’t have the necessary skills, it’s best to hire a certified electrician to install the generator for you. Maintenance is easy, with most tasks consisting of routine oil changes, filter replacements, and general inspection. The generator is easy to use, with a simple control panel and an easy-to-read instruction manual.


The Generac 7043 Home Standby Generator is quite impressive. It has an impressive start-up time, taking just a few seconds to start providing power. Voltage regulation is also spot on, delivering a clean and stable frequency. The generator can handle loads of up to 22 kilowatts without any issues. Additionally, it’s fuel-efficient, with a lower consumption rate than many other standby generators in its class.

Pros and Cons

Some of the key advantages of the Generac 7043 Home Standby Generator include its durable construction, automatic transfer switch, mobile link compatibility, and excellent performance. However, it has some minor drawbacks, including its high cost, the need for professional installation, and the need for a dedicated fuel source.


Overall, I would highly recommend the Generac 7043 Home Standby Generator to any homeowner looking for a reliable backup power source. It’s durable, efficient, and packed with features that make it easy to use. While it can be a bit pricey, the benefits of owning a standby generator are well worth the investment.
