Now that you have decided to purchase a generator, there are several considerations to keep in mind when choosing a unit to suit your needs. Choosing the right generator is not very difficult if you take the time to analyse your requirements carefully. We are always here to help and if you have any questions at all, please ask.
Smaller portable generators are available from 2Kw upwards. These small portable units can be used for camping, market stalls etc and can even be used in emergency situations to power smaller loads using an extension cord. Some even come with an automatic voltage regulator (AVR) which means that thay can be used to power various electronic equipment such as a computer.
For homeowners and small business owners thinking of emergency power supply, portable generators from 5Kw upwards are useful but sometimes it may be more economical to purchase a stationary system and power the whole house or business.
In general, a three or four bedroom house will use an average of around 20amps of power.
5Kw will give 21Amps power
6Kw will give 26Amps power
10Kw will give 43Amps power (enough emergency supply to fully power a mid-large sized home or small/medium business)
Once you calculate your power requirments, keep in mind that it is recommended that the generator runs at around 75% autonomy. For example if you require enough power to supply 30 -33Amps we would recommend that you purchase a 10Kw generator.
Emergency standby generators can supply electricity to the majority of your house, not just to a few selected circuits. The all-weather generators are installed outside and are wired through an automatic transfer switch to the main electrical panel. These units run on natural gas or diesel. Some systems can even be connected to a home's natural gas line, eliminating the need to fill fuel tanks.
When the power goes out, there's a slight delay of a few seconds, then the generator automatically kicks in - whether you're home or not - and continues running until power is restored, when it will automatically shut off. If you have critical applications such as life support equipment, computers or similar systems, you can install a UPS (uninterruptible power supply, a battery in a special box), and there will be no interruption of power to these devices while the generator starts up.
Portable generators can be heavy, therefore we recommend buying a trolley kit if you want the generator to be fully mobile.
