How much power do I need?
Industrial
Do you want to support all or part of your factory load? Unless you wish to separate essential from none essential services, then the generator is normally sized to the main's incoming supply breaker rating." "If the generator is to support only part of your building and essential services then you could use a small lower cost generator. But be careful for most electric motors need far more power to start them than to keep them running.
Domestic
Look over the table below and make a list of all the items you would like to use when the mains electricity has failed and you are using your generator.
Remember that the fridge and freezer only use power for a few minutes each hour.
Will you use the dishwasher at the same time as the washing machine or tumble dryer when you are using the generator?
Your outside security lamps will come on as the car comes down the drive but only for a few minutes and then will it be at the same time as you are using the washing machine?

OK! So now we have a list showing just how much power you use. Don't forget you can't run all the appliances at the same time so rationalise just what would be running.
The worst case to have a power cut could be when your washing machine (3kW) is in the middle of its heat cycle - the dishwasher (2.5kW) is trying to clean up last nights dinner and you have just switch on the kettle for a cup of tea.(2.8kW) Hey! - a total of 8.3kW and that's not to mention the radio - a few lights - fridge - freezer. So we could be up to around 9kW.
That's why DSI recommend the 10kVA P12000 Power Station as the best value for money.
