Guidance to determine the size of gen-set

Do you want the generator to power part/all of your home/office/caravan etc?

dentify all appliances and tools that will require generated power.
Determine the wattage of each appliance and tool. Take particular care if applying any type of motor load as they present special starting needs that can require up to six times their running wattage. Please refer to our typical power table. We would recommend that you always use the figures given in the starting column.
Total up the wattage of above, bearing in mind that if you co-ordinate your power usage wisely you do not have to operate everything at once. Therefore for emergency domestic use you may not necessarily have to operate your vacuum cleaner, dishwasher, washing machine etc. For industrial/DIY use you may be able to run only one or two tools simultaneously.
Convert the total wattage into KW (1000 Watts = 1 KW) we would suggest, although not absolutely necessary, that you over size your generator by up to 20 % to give you a comfort factor. For example, you have calculated your total load at 3 KW, budget for 3.6 KW.
Remember: The gen-set should be started first and a few seconds should be given to allow the voltage and frequency to stabilise prior to the load being connected.
