How Long Do Inverter Generators Last?

how long do inverter generators last

If you’re looking for an alternative to a standard generator, consider inverter generators. These machines are quiet and safe for sensitive electronics. Some of them feature extra-large fuel tanks that can last up to 18 hours. Fuel efficiency is an important factor to consider when buying an inverter.

Fuel efficiency

Fuel efficiency is an important factor for inverter generators. These generators are more fuel-efficient than traditional generators because they can adjust their engine speeds according to the demand for power. In a conventional generator, the engine is continuously running at full speed no matter what the load is. Because of this, the fuel efficiency of an inverter generator is higher.

Inverter generators are quiet and lightweight. They can power sensitive electronics during power outages and recreational activities. They may cost a little more than traditional generators, but they could save your hearing or expensive electronic equipment.


Inverter generators run on fuel. They have a fuel tank capacity of one to two gallons, and typically last for eight to 10 hours on a full tank. Compared to gasoline-powered generators, which run on gas, inverter generators are more environmentally friendly, with two modes: economical and environmentally friendly. They can also vary between these modes depending on the load they’re producing. For example, the Generac 7117 GP2200i 2200-watt portable inverter generator can last up to 10 hours on a single tank, and has an economy mode.

Inverter generators are also quieter than conventional generators. They’re much quieter than traditional open-frame generators, with noise levels around six decibels, compared to around seventy-six decibels for an open-frame generator. This makes them ideal for campgrounds with noise restrictions.


Inverter generators are considered consumer products and have safety standards under the CPSA. Under the CPSA, the Commission may issue mandatory standards to protect consumers from unreasonable risks posed by consumer products. The Commission may also issue a notice of proposed rulemaking, or NPR, to solicit public comments. The NPR must be written in a way that prevents harm, reduces risk, and promotes product safety.

A review of fatalities involving inverter generators indicates that the number of fatalities is still low. In some cases, the fatalities occurred outdoors or in structures that were not comparable to the model structures developed by NIST. However, the Commission believes that reducing the emission of generators may have reduced fatalities – especially in enclosed, large spaces.


Proper maintenance is essential to ensure that your inverter generator continues to run at a high efficiency level and lasts for years. It also ensures that the machine is quieter, which is important if you need it to run for long periods. The manual that comes with your inverter generator should contain instructions for performing various maintenance tasks.

Before starting the maintenance process, make sure to check the oil level in your inverter generator. You should change the oil after 20 hours of continuous use and every six months. You can check the oil level using the oil dipstick. Once you find it is low, you can change it by screwing the oil discharge pipe into the oil reservoir and tilting the inverter generator forward to pour the oil. You should also clean the air filter in your inverter generator after every 50 hours of use or after three months.
