Duromax XP12000EH Generator Review

When a power outage strikes and the lights and appliances stay on, homeowners with backup power generators know how relieved they are. The ability to be the only family in the neighborhood with a working air conditioner isn’t the only benefit of owning a backup power generator. 

When strong storms knock out the power in your home, a home power generator can keep your family safe and comfortable. Adding a home power generator may be a simple home improvement project.

People usually buy backup power generators in the days leading up to or after a large storm. This can result in a hasty decision and a generator that is too small for your home.

Consider your alternatives before a storm strikes to ensure you get the proper generator for your needs.

What is a Standby Generator?

Standby generators, also known as whole house generators, are backup generators that provide power to your home automatically when the power goes out. When there is a brownout or blackout, the whole home generator can immediately start providing electricity within 20 to 30 seconds. 

Standby generators, typically positioned directly outside of your home, similar to an HVAC system’s exterior unit, and require professional installation. A standby generator is linked to your home’s natural gas or propane pipes during the home generator installation process.

So it can supply power indefinitely for as long as you require it. While a standby generator normally powers your entire home, it is also tailored to only power specific appliances and devices, depending on your need.

Advantages of Standby Generators

Access to Adequate Electricity

When it comes to standby generators, each residence will have its own set of requirements. A skilled electrician can assist you in determining the appropriate size unit for the task at hand while the main power is turned off.

Peace of Mind

You may rest easy if you install a standby generator that can turn on automatically when there is a power loss – even if a major storm is approaching. Even if the local utilities are out, your family will be cozy. There’s no denying that peace of mind is invaluable.

There’s No Need to Refuel.

The best standby generators can connect directly to your home’s existing fuel supply. This is true whether the fuel is liquid propane or natural gas. You won’t have to walk outdoors in the middle of a storm to replenish your generator as a result of this.

Automatic Power Outage Detection

You can program some modern standby generators to operate automatically. They can detect a power outage and turn it on within a few seconds of detection.

This means you won’t have to do anything to ensure that your backup generator starts up when it’s needed. As a result, when the power goes out, you won’t have to wait long for the essentials – cooling, heating, lighting, and refrigeration – to come back on.

Generator Maintenance Tips

A generator can survive for decades with appropriate care, but it must be maintained. A generator, like a balanced diet and regular exercise, requires regular maintenance to avoid breakdowns. 

The better your generator’s maintenance, the longer it will run without needing costly repairs, which can save you a lot of money on pricey parts or possibly replacing the entire machine. 

Continue reading to learn how to keep your generator safe and ready to use when the power goes out.

Replace the Oil

Regular oil changes are one of the most crucial aspects of generator maintenance. The frequency with which you should replace your oil is determined by various factors, including:

Based on the following factors, industry experts recommend changing the oil every 50 to 200 hours of operation. For example, because newer, state-of-the-art models burn cleaner than older versions, they may require fewer oil changes. 

However, if your generator is used in a location where there is a lot of dust or impurities that can mix with the oil, you may need to change the oil more frequently.

Keep it Clean


A generator produces energy by combining the rotor and stator, two pieces found inside your generator. Rotors and stators are known to gather dust, dirt, and other pollutants while in use.

Your rotor and stator will not be able to generate energy as efficiently as possible if you allow too much filth to accumulate in your generator. It’s also likely that you’ll burn through the two components faster than usual.

You must clean the air filters in your generator to remove debris. It’s also a good idea to check the air filter for dust on a weekly basis, regardless of how often you use your generator.

Increase the number of times you inspect your generator if you reside in a dusty environment. These measures will ensure that your generator is ready to use when you need it the most.

Use New Gas Instead of Old Gas

Most homeowners are unaware that they should empty their generator’s fuel tank after each use. Cleaning out the tank guarantees that you’re using clean, efficient fuel while also preventing erosion and damage to your equipment.

Store it in a Safe Place

You’ll need to take a few precautions after each use to extend the life of your 1portable generator. Double-check that the gasoline lines are also empty in addition to the fuel tank. To prevent corrosion and improve the life of your equipment, keep it in a cool, dry location.
