What to look in a generator.

Domestic of professional use - Some generators are designed for leisure use, hobbyist, others are made with the pro user in mind. These are made for running things like workshops and commercial use

Wattage -=This is something you really need to consider before you buy, this is the power the generator can produce when in operation. You will need to know the total wattage is you wish to power.

Equipment - You need to know what types of equipment you want it to power, for instance, if you want it to power sensitive equipment such as PC/laptops, or TV’s you may need an inverter generator.

Fuel type - Yes, you have options on what type of fuels your new generator can use, typical fuels will include petrol, diesel, LPG or some will even offer a dual fuel option where it can run on either petrol or LPG.

Standby/backup or specialist generators - These days the standby or backup generators are becoming very popular, it does not matter if you are looking to protect your home, office or a large factory, we are able to supply a suitable unit for your requirements. We even have options where the generator will be autonomous in its operation.

What is the total wattage required?

We get lots of calls that ask us - What size generator do I need? The answer will depend on factors such as what is it being used fir? All model are rated to a certain wattage, you must work out the total wattage or power you need, it doesnt matter if you want to power just one laptop or a large factory, you will need to know this. The best way to do this is to make a list of what you want it to power and add up the wattages ballpark.

Our list

  • Fridge 600 w
  • Portable heater - 2000 w
  • Laptop - 300 w 
  • Lights 30 w ea x 2 - 60 w
  • Total = 2860 w
  • + buffer of around 20% - 552 w
  • New total = 3552 w

In the above example, we should be looking for a 3500w or 3.5kW generator to power the items we have on our list.

Types of Generators

Inverter generators 

Due to the fact that these engines are more complex, these will cost more than a comparable output traditional portable generator. 

Inverter generators are also a lot quieter when compared to conventional portable ones, This is partly due to being incased and partly due to them being able to throttle up and down depending on the load required, they also tend to have better exhaust systems to help the lower sound.

They are fuel-efficient and produce fewer emissions.

Portable generators

Typically run on petrol and can be used off or on your property. Never to be used in an enclosed space. Several models will offer an electric start. They run at 3000rpm and are at a fixed speed when in use and have higher noise levels than inverter generators. These are great foor running jobs on sites and running power tools etc.

Standby or backup generators

These units will need to be installed so factor in some extra budget when looking at these, they can start/stop automatically in the event of power cuts. They also have self-diagnosis and will let you know when and what maintenance is needed. Some can even send a text or email alerts to keep you up to date.n 

Typically runs on diesel red or white but other fuel options like natural gas or and LPG can be had. They come in sizes from 4kW upwards to very large units that can power tower blocks or large factories

These will come in both 3000rpm and 1500rpm, the 1500rpm units will enjoy longer lifespans with bigger service intervals.
