The rise of industrialisation and urbanisation has meant that the need for adequate and reliable power supply has become important. Not only has this been the case in the business front, but homeowners have also resorted to alternative power supply to combat the impact of outages, load reduction and loadshedding from the national grid.
DIY & Industrial Trade News spoke to generator suppliers who provided expert advice for retailers to share with their customers on how to decide on the best generator for their needs.
L&G Tools
It is essential for retailers to ask consumers which appliances they plan to power with a generator. The required generator size will depend on the number and type of appliances that need to be powered at the same time. Consumers must be aware of both the running wattage and start-up wattage, if applicable, of the appliances they wish to run. A formula can then be utilised to calculate the total required wattage from a generator. The range of generators available to Trade Professionals spans from 2.8kW to 10.5kW.
For a more detailed explanation on how to decide the appropriate size of generator needed, retailers are encouraged to visit our YouTube channel and watch the following video:
1. What are some key points consumers should know about the impact of fuel type on the overall performance of their generator?
Diesel generators are ideal for powering large machinery, while petrol generators are better suited for households and smaller machinery. Diesel generators are known for their superior fuel efficiency, as diesel burns 50% slower than petrol. However, the rising cost of diesel due to regulations and higher emissions produced by diesel fuel are important considerations. On the other hand, petrol generators are generally easier to start and more cost effective to maintain.
2. Some generators are also suitable for DIY construction projects, home renovations or even home workshops for DIY enthusiasts. Which generators are best suited for such projects that retailers can recommend to customers?
Petrol generators are ideal for powering general household equipment such as lights, pumps, domestic appliances, and power tools making them a popular choice among DIY enthusiasts. On the other hand, diesel generators are better suited for powering large construction sites and industrial machinery.
3. With renewable energy being on the rise and people exploring their options , what are some of the notable generator technologies that have emerged that retailers can share with customers interested in integrating a generator with other renewable energy sources?
Sinewave generators offer a reliable and stable power supply that closely mimics the electricity received from the grid. This consistent power source greatly minimises the risk of damage to our devices caused by power surges. In addition, sinewave generators run with significantly less
noise compared to traditional generators. Trade Professional provides Power Stations and Inverter Generators equipped with pure sine wave technology, catering to customers seeking a renewable energy solution as an alternative to traditional generators.

Generators are essential tools that provide power during outages, but it is important to be aware of the potential dangers associated with their use.One such danger is the production of carbon monoxide, a colourless, odourless, and poisonous gas that can cause serious injuries or even death if levels become too high. To prevent this, generators should never be operated indoors, including in homes, garages, or other enclosed spaces.
An automatic voltage regulator (AVR) is a crucial component found in generators that serves the purpose of automatically adjusting voltage levels, ensuring a consistent output of power. Trade Professional generators come equipped with an AVR to maintain stable voltage levels.
Consideration should also be given to fuel availability, as a generator is of no use if it cannot be fuelled. Additionally, the noise level of a generator is an important factor to consider. Generators are labelled with decibel ratings, with inverter generators being the quietest option, running between 49 and 70 decibels. Diesel generators, on the other hand, typically have noise levels of around 75-85 decibels.
Another important feature to consider is the start method of the generator. Electric start generators offer convenience and safety, as they can be powered on with the flip of a switch or the turn of a key, eliminating the need for manual pulling of cords which can be physically taxing and time-consuming, especially for older individuals.
In conclusion, when choosing a generator, it is essential to consider factors such as total wattage needs, fuel availability, noise levels, and start method to ensure you recommend the most suitable option to suit the needs of the buyer.

Ryobi
With our wide range of Ryobi generators and generator inverters there are multiple options for various household requirements. The most reliable way to calculate which generator is best for your customer’s household, is by calculating the total required wattage necessary. Watts is calculated by multiplying the voltage needed in Volts by the current strength in Amps.
For example, if your household uses on average 500 Volts x 3 Amps you need a +1500-Watt generator or inverter generator. However, If you purchase a generator that provides 3000 Watts you build in extra capacity to ensure that you do not overload the generator. Suitable options would be the RG-3500 Generator or the RG-3000i Inverter Generator or the RG-3200i Inverter Generator.
A typical household would require the following to run during a power outage:
- Refrigerator
- TV
- Decoder
- Kettle
- Wifi
- Plugs
- Lights.
It is not recommended to run household items that use an element that draws high levels of Wattage such as microwaves, geysers, ovens, stoves, hairdryers, etc.
