Generators – Alternator Style

A Generator is a useful piece of powered equipment for all households, business operators, builders, farms and an absolute necessity for Civil Defence and disaster management for portable power.

QUALITY            When you need emergency power in a hurry you need to make sure your Generator is going to work, and work properly. A Generator is definately something that you "get what you pay for".

OUTPUT SIZE  There are several things to consider when choosing an Alternator Generator – quality and load factor. You need a Generator with sufficient maximum kVA output to start up and run all of the appliances you wish to operate.

FAQ's

How do I work out what size Generator I need?

There are many guides available to help you do this (go to ‘How To’ guides). Essentially you need to add up either the wattage or amperage of each of the appliances with an electric motor, running off the Generator AT THE SAME TIME. Add at least 50% extra to cover start-up capacity. Add to this any appliance or lights that will have straight resistance. Add 25% to this figure. Add the two results together. This will give you a minimum approximation of the required kW output or KVA. If you’re using Amps simply multiply the Amp total by 240 (240 volts) to reach the Wattage total.

Can I hook up a Generator to my house wiring?

Yes, in many cases you can. You will need to choose a Generator with sufficient capacity to either run a whole house or the selected circuits required to power up. It would be best to check with a registered electrician for your KVA load requirements before making a buying decision. You will most likely need to integrate a Mains Power to Generator Transfer Switch system. Otherwise the strategic use of a multi-box and power-leads can get you out of trouble in an emergency. Please note: this emergency power supply set up cannot be connected directly through your switch board. Another option is the Kohler Residential Generator. If you have any doubts, always contact a registered electrician first.

Is quality a major factor when purchasing a Generator?

Yes, absolutely – quality is the major consideration when purchasing a Generator. The market has been flooded with low quality, cheap, counterfeit Generators – many of which will have no backup, limited reliability, or even potential short-out dangers. Stick with a known brand purchased from a Generator orientated company where back-up service can be guaranteed.

Should I use a Petrol powered or Diesel powered Generator?

When choosing your engine type, there are several things to consider.
1. How many hours per day/week/month it will get used.
2. Average load factor. 
3. Price of the Generator itself.
4. Fuel costs may be a consideration.
Simply put, Diesel engines are designed for long-term, high-load running operation. Unless your Generator requirements are an all-day, every day requirement on an ongoing basis, Petrol powered generators will be the most cost efficient.  

What is the difference between an Inverter and an Alternator Generator?

An Inverter Generator produces pure sine-wave AC electricity from an electronic processor- controlled inverter power-pack which delivers a near perfect electricity output. Pure sine-wave electric power will not harm delicate and sensitive electronic equipment. A traditional style Alternator Generator produces AC electricity using an engine rotating an Alternator. However, the sine-wave from this type of Generator is not perfect. Most modern quality Generators have an AVR (Automatic Voltage Regulator) fitted. This allows most electrical equipment, except delicate electronics equipment, to be used without any fear of damage, making the Alternator Generator fine for most uses.
