Honda Generators – What size Honda Generator do I need

Generators
Generator Use
Honda’s EU Series Generators can run at a variety of speeds, so when you’ve been operating an EU Series Generator on Eco-Throttle at low RPM’s for some time, make sure you turn the Eco-Throttle off and run the unit at maximum load for a period.

Depending on how you will use your generator, there are different categories to meet your needs. This can include recreation, home standby and construction. Honda also offers Inverter Generators. Inverter generators are smaller and lighter as power is created electronically and not through a conventional alternator. Inverter power offers the cleanest power output, ideal for sensitive electronic devices.
It is not recommended to connect your Honda generator to your household power supply, unless done by a qualified electrician. If you are using a generator for home standby, for example, if you want to run your refrigerator, you’ll need at least 2,500 watts or more. And if you want to use a transfer switch so that power can go directly into your home, you’ll want a generator with at least 3,000 watts. (Click here for more information on transfer switches from the Honda US website).
You’ll also need to consider the maximum and rated power of the generator. This is important depending on what items you want to run off your generator. Items such as toaster, lamps, and coffee makers are resistive, or constant loads and their total load can be calculated at amps x 1. Items such as saws and drills are reactive loads and while the running load may be small, the starting load should be calculated at running amps x 3. Remember, after the initial start, less power is required for actual operation.
Always remember that simple power management will allow a smaller generator to do a big job. Very seldom are all tools or appliances operating simultaneously. When calculating power requirements, consider the starting requirements are only for the initial start and then additional tools may be operated.
Remember Ohm’s Law from High School Physics?
Watts = Volts x Amps
Amps = Watts/Volts

So if you have two of the numbers (e.g. volts, amps) then you can find out the other (e.g. watts). This can help you to determine the rated power that you’ll need from your generator.

    Great post! I am just starting out in community management/marketing media and trying to learn how to do it well – resources like this article are incredibly helpful. As our company is based in the US, it?s all a bit new to us. The example above is something that I worry about as well, how to show your own genuine enthusiasm and share the fact that your product is useful in that case.

  2. Wow! You really covered this topic well. Are there other resources that I should check out?

  3. superuser says:

    Thankyou for you visiting you may like to visit http://www.hondampe.com.au as they also have helpful information on Generators

  4. I absolutely understand everything you have explained. In fact, I browsed throughout your additional blogposts and I do think you happen to be completely right. Great job with this particular site.
