how big of a generator do i need to power my house




 to know the a generator size for your house first you will have to know the total wattage of your home appliances ,
most  electric  home appliances are rated based on the amount of energy they consume at a time.  All electric appliances almost have two ratings, the starting power and the running power.
 The starting power is the watt required by an appliance to start while the running  watt is the power required by the  appliances.  Home appliances are  rated using the running watt.
 For example  a 300 watt strimmer can have a 500watt starting watt a 600watt microwave can have 1700watt starting  watt. A 7500watt power shower can have a starting watt of 10500 watt. A 4 watt smart phone  charger can have a starting watt of 7watt a 10 watt  table fan  can have a 25watt starting watt, a 10 watt tablet charger can have 25watt starting watts,
Alternatively some appliance have same starting and running watt for example a 400watt submersible water pump can have a starting watt of 400 watt, a 500watt washing machine can have a running watt of 500 watt. a 3000watt hot water immersion heater has a starting watt of 3000watt,
Similar generator are also rated, there are 2000 watt generator, 3500 watt and even 12000 watt generators, like electric appliances generators also have  two ratings , the starting watts and the running watt. The starting watt is power required by the generator to start while the running watt is the amount of load the generator can support.
 Therefore when selecting a generator  choose the a generator that can support all you rhome appliances, how do you do that , you sum up all the stating watts of you home appliances if it is less than the gen running watt , then you pick the gen, you can find any electric device wattage in the user manual.
