Introducing the Whole House Generator

WHOLE HOUSE GENERATOR

Do you know what a whole house generator is? If you don't, you definitely should. In this article, we shall tell you everything. Let's start by defining it. A whole house generator can give backup electricity for the whole house, during a power crisis or a power outage. They are necessary because no year is complete without its share of blackouts, and since we depend much on electric appliances, we need to have power at all times. A standby generator cannot be used continuously - in fact, it is just meant to be used for short periods. So you need something that will provide you electricity throughout the day. Enter the whole house generator. Their generation capacity is measured in kilowatts, and it's a good idea to install an automatic transfer switch (ATS) also. If the electricity power gets cut off, or if voltage is low, then the ATS would disconnect your house temporarily from the utility grid, and the generator would start working.

So what kind of whole house generator should you opt for? The size depends on how many electric items you would need to operate during a blackout. Usually, a 12-KW generator seems to be enough to meet a typical family's needs. But if you think you can get through without luxuries like air-conditioning, or even hot water baths, for some time - then perhaps a smaller whole house generator would do the trick - and it would cost much less as well. So how do you go about choosing? A good method would be to sum up the wattage of the electric items you think you'll require. However, you should always avoid online watts calculators. When doing calculation, you should take into account the fact that all appliances are unique, so depending on the energy efficiency of each appliance, your results can vary.

A whole house generator can give power to your house even in times of power outage. So you can use essential appliances like the air conditioner, your refrigerator and heater, and even the lights. It works by converting mechanical energy into electrical energy. In residential applications, the AC power generators use small engines to produce this mechanical energy. The spinning shaft of the engine is used to create an alternating magnetic field, through a coil, and this induces electromotive force. When it comes to a whole house generator, you can either choose to buy a portable one, or a stationary one (a standby model). These run on different fuels like gasoline, natural gas, diesel, and also liquefied petroleum gas (LPG). The gasoline portable models are usually quite easy on the pocket, you could get a 3000W set for $300. However, their run time is usually short, and you would have to refill their tanks many times a day, if you're running them continuously at rated load.
