A generator simply has an engine that uses natural gas or propane, and sometimes for large power output diesel as a fuel to generate electricity. When the engine generates the power, it gets hot, and to cool it down, a pump is provided to circulate the coolant through the engine, which will then flow in the radiator.

A fan will blow the air over the radiator, releasing the heat outside and cooling the coolant.

What Size Standby Generator is Best for My House?

The main component for a standby generator is a transfer switch, and it is a smart controller that does the coordination. When the power outage occurs the transfer switch senses the outage and gives the signal to the generator engine to start.

After giving it a few seconds to stabilize, the connection is made with the circuits of the house, which needs to be powered.

What is a Standby Generator?

Note this, before making a connection, it disconnects the utility line to prevent the problems arising due to back feeding. The same goes for when the power returns, the transfer switch senses that the power has come back, it will disconnect the generator from home and will connect the utility supply.

After giving some time to the generator for cooling down, it will be turned off. This cycle will repeat in every power outage condition. Some sophisticated transfer switches in the market come with the power management feature to supply the power only to priority circuits when the power goes out.

If two power-consuming appliances are connected, then it will keep one waiting until its turn comes. Portable generators and standby generators are significantly different from each other. One obvious difference resides in their name; a portable generator can be carried along wherever you require power, whether it is a campsite or a job site.

On the other hand, the standby generators are made to sit in one place, and they don’t have any handles or wheels to move them. They are hardwired to the electric circuits of the house. A portable generator will be small and will have a small engine that can supply power for a brief period of time, and they are suitable to run only essentials during a power outage.

What is the Difference Between a Stand-By Generator and a Portable Generator?

The standby generator is designed to power for an extended period of time and can supply power to almost all house appliances. Another difference is that you will have to manually turn on and turn off the portable generator when you need power, and they need to be regularly checked for any faults and need to be periodically maintained to ensure long life.

But if we talk about the standby generators, then because they are connected forever to the electrical circuits of the house, they sense the power condition on the utility line.


If the power goes out, then the standby generator automatically starts, and when it comes back, the generator will automatically shut off.

Moreover, automatic generators run the automatic test on them and notify the user if there is anything wrong with the system, so no manual checkup is required. When it comes to the portable generator, then they need to be run outside. If used inside, then the accumulation of the exhaust from these generators can turn out to be fatal if breathed in.

If they are outside, there is a risk of theft.

But for the standby generators, due to their heavyweight, they don’t appeal to thieves much. Other than that, if you want to run the portable generator as a backup generator, then you will have to first accumulate the fuel, and the fuel tends to evaporate.

This doesn’t always make it possible to have fresh fuel. While for the standby generator, you can directly connect them with the existing propane or natural gas supply to your house, and it will be ready anytime you want it to work.

If not, and if the voltage and amperage are given, then by multiplying them, you will get the wattage.After that, sum up all the wattage of each appliance that you chose to power in an outage.
