Is a portable generator fuel efficient? Fuel efficiency varies among portable generators based on factors such as engine type, load and technology. Inverter Technology, which varies the engine speed based on power demand and uses 20-40 percent less fuel than models that run at a constant speed For example, a 2000-watt inverter generator will provide power for 10-12 hours from a single gallon of the gas tank if its running at 25% load.
A Generator at the 5000-watt tier runabout 0.75 gallons an hour @ full load, and that allows for approximately 6–8 hours of operation off a single 5-gallon tank under no-load conditions. As an example, Honda’s EU2200i 2200 watt portable inverter generator has a (gulp) really fuel efficient veggie,tired and all its digits no doubt calculating the revenue from burnt gas — belched in their direction — topping it off 🙂…8.1hrs @ 25% load on a single tank of just under one gallon. Conversely, conventional models not using inverter technology use upwards of.5 more gallons of fuel each hour under similar conditions so that inverters are the economical decision for prolonged or lower load jobs.
The dual-fuel models increase user flexibility, users can change between gas and propane consumption at a lower cost depending on what is cheaper in that specific time. Propane neither burns as clean nor does it produce anywhere near the same amount of energy per gallon (10-15% less) than gasoline. But propane can be stored for longer than gasoline, so it offers a viable backup method (even if you keep or buy some of this fuel occasionally).
Because of that, and because most portable generators are now required to meet EPA and CARB standards, newer models tend to emit up to 90% fewer pollutants than older ones. A slightly more sophisticated feature is the eco-throttle systems found in generators from major manufacturers such as Honda and Yamaha. It turns down the engine speed so you’re not wasting power when the load demands are lower (like running alone on a TV).
In general, a smart and right choice to make your cost low as well eco friendly(generator fuel usage also use when you calculating this). Newer models of portable generators are also more fuel-efficient as they incorporate features such as inverter technology, dual-fuel systems, and eco-throttle functions, all thanks to newer computer technology where users can harness the power sustainable generation for years on end.
