Choosing the right generator

Herbos Equipment Digital Inverter Generator


Don't know what to look for when choosing the right generator? You're not alone. Follow the selection guide below. As your trusted generator supplier, we'll show you how to make the right choice.

Portable Generator
A Portable Generator comprises two main components: A gasoline or diesel-powered engine, and an alternator. The alternator features a rotor, which rotates inside a stator (fixed). The engine's power is used to rotate the rotor inside the stator, which generates AC power. The benefits of portable generators are broad, in home, office, farm and job site environments. Portable generators have also made outdoor events and projects much easier to handle - particularly when access to electricity is an issue in open outdoor spaces such as fields.

​Traditional Generator
Traditional generators produce power by using an engine that rotates two large coils of wire (the "rotor") within a circumference of magnets (the "stator"). Each full engine rotation produces one complete sine wave of AC power. To produce the standard of 50Hz, the engine must maintain a constant speed of 3000RPM. (3000 revs/60 seconds (1-min) = 50Hz). Regardless of the load, this traditional style of generator must run at full speed to provide the relevant power.

Inverter Generator
An inverter Generator is normally used in situations where power is needed for sensitive electronic equipment. This could include PCs, TVs, mobile phones, and various instrumentation. Inverter Generators are often chosen when portability or size is important, and/or where minimal noise is desired. The lower noise level is desirable when using the inverter generator in public spaces such as events, running food trucks and food trailers, as well as on camp sites running the motor home, caravan or appliances in the tent.

Herbos Equipment's Range of generators offers generators that provide convenience, functionality and portability. Backed by advanced generator technology and functionality, our range includes leading brands at very competitive prices.

What do YOU need to power?
When choosing the right generator, there is one question that matters most: "What do you need to power?"

Make a List
Write out a list of the appliances, tools, and lighting that you wish to use at the same time. For example, how many lights will you need to run alongside your power tools? Will you need to run the oven as well as the microwave simultaneously? These questions must all be taken into account when choosing the right generator.

How much generator wattage do I need?
The list below offers advice and guidance on the most common wattages for home appliances and those in the workplace. For exact figures, we recommend that you check the nameplate or instruction manual of each individual appliance. Where applicable, we’ve also listed the “starting wattage” or “surge wattage.” This refers to the amount of wattage needed to start an appliance with a motor. This could be up to three times the wattage required to run the appliance, which is why this must be taken into account.

It’s important to take note of the maximum and rated wattage output of a generator – which all have. GT POWER Generators are engineered to work at their maximum rating for up to 30 minutes. What is "rated power?” Well, this refers to the level at which a generator can be operated, continuously. Typically, this is 90% of the generator’s maximum power. 

The GT POWER Portable Generator Series features a range of machines, from 900W to 9000W.

When choosing the right generator, also take note of the following:
  • How much does it weigh?
  • How much sound will the generator make?
  • What is the engine type? (2-stroke, 4-stroke, or diesel)
  • What is the fuel capacity?
  • What is the generator’s starting system? (electric or EZ start recoil)
  • How much does a generator cost?

Calculate your total power needs
This chart lists average appliance power requirements. Your particular tool or appliance may require more or less than the listed wattage. Begin by adding up all of the “running wattage” requirements for the appliances you need to power simultaneously. Next, add the highest of the “starting wattages” to your total. Now, you’ll know approximately how much power you need to run your appliances using a generator.


Important Note: Always choose a generator with more capacity than your load requirements. While it will cost a little more, you’ll quickly earn this back in generator fuel savings. You’ll also save on generator service costs, seeing as you won’t have to constantly run your generator at full load.

This chart lists average power requirements. Your particular tool or appliance may require more or less than the listed wattage.

* Where START wattage is the same as RUN wattage, this means that you won’t need any additional power to start your generator.
