Backup Generators for home use can sound difficult but actually their concept is pretty simple. Here is some simple information to help your understanding
Residential generators may seem tricky but surely their concept is quite simple really. Home Generators commonly known as as standby generators supply power to your home in case of power loss. So the idea is, that when you are disconnected from your mains supply, your standby power kicks on and as such you do not have to go through the hassle of a loss of power.A standby generator in your house is generally installed such that it monitors your mains power supply all the time. If your mains power snaps out, your ATS (automatic transfer switch) will safely shut down the utility feed wires and connect to the standby generator feed. Do not forget the same does not happen when using a portable generator; this has to be connected by hand as portable generators do not start automatically.
A signal is provided, starting the standby generator and this provides voltage to your home circuits. Automatic generators permanently monitor your mains utility power and invert the switch over as soon as the mains power failure is over. Your generator then goes back to standby setting, waiting for the another blackout. This situation starts systematically on it's own without any input from you. There isn't even a need to supply fuel, as your generator will run off your own supply, that is has accumulated.
Your home use generator will run itself not less than once a week; this is only a checkup and insures that it is in good order. You can normally control this yourself and set the frequency levels. This is a great maintenance check for your generator, and also oils the engine and boosts the energy source.
