So, what is it that makes Hondagenerators so good? Is it the unquestionable durability of our commercial grade engines? The leading edge technology? Quietness? Well, every user’s demands are different but, whichever Honda you choose, you can be sure it’s built without compromise to provide you with the most reliable and efficient power source you can work with.
Now you’ve made the right choice and decided that a Honda generator is for you see below on how to choose the right generator.
Choosing the right generator - output // noise // power stability // size & portability // starting
Your power requirement - To determine the ideal generator for your needs, just follow these simple steps:
1) Identify the tools and appliances you intend to operate with your generator. 2) Determine the power requirement for each product (allow for starting load, see table below). 3) Total up the wattage for the products which may be operated simultaneously (examples right). 4) Choose a generator with a rated output of at least your total, plus around 10% contingency.
Motor starting load guide Motor starting is an important consideration when buying a generator. Keep in mind that induction-type motors,like those that run sump pumps, refrigerators and compressors, typically require 2-3 times their listed running watts to start.
The type of 'load' Electrical appliances have different power requirements - some products such as refrigerators, typically require two to three times their normal running power to start, and a circular saw requires more power when the blade is cutting – the loaded requirement. Appliances with a 'resistive load' have a constant starting and running current (TV's, cookers, hi-fi's, kettles and light bulbs fall into this category). Items such as saws and drills are 'reactive loads' and while the running load may be small, the starting load should generally be calculated at running amps x 3. Remember, after the initial start, less power is required for actual operation.
Power management 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. Most electrical appliances have their power specifications on the data plate. This information is also usually found in the appliance owner’s manual.
