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 0. 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.

Power Inverter Wattages - How Much Power Do I Really Need?

!±8± Power Inverter Wattages - How Much Power Do I Really Need?

From 100 Watts all the way up to several thousand there are plenty of different inverter power options to choose from, so how do you know which power inverter to choose and what rating will best suit your needs without paying for something you don't need? Well to answer that the main thing you will need to do is work out how much power you think you will be using, and from there it is a matter of just shopping around.

So let's get started. First you will need to determine what you actually want to run from the inverter. In general the more you want to run from a power inverter at the same time the more power you will need, however each electrical device and appliance will use a different amount of power and so it is important that we get an idea of how much power the appliances you want to use draw.

Most electrical equipment will have some sort of power rating on it or its power supply, so this makes it fairly easy to have an idea of how much power you will be using. For instance, a 100W light globe for instance uses 100 Watts. Most appliances will have their rating underneath or kind of hidden a way a little so you might need to search around a bit but you will usually find it pretty easily.

As a quick tip for you, from our experience electrical device power ratings are not hugely accurate, especially when it comes to more complex equipment like laptops etc, and are quite often measured under ideal conditions which usually wont reflect real world circumstances, so adding an extra 10 or 20% on top of what something is rated at is probably a better indication, and will also give you a little head room too which is always a good idea.

So as an example let's say that you want to run a light rated at 60W, a fan rated at 100W, a laptop rated at 150W, and a small TV rated at 100W. Adding them up will give us 410 Watts. Taking the above into account and adding an extra 20% will give us a little under 500 Watts, so a power inverter around that value will be perfect. For this setup I would recommend getting a 600W power inverter as not only will this give you a bit of extra juice in case you decide to run anything else, but it is always better to get an inverter rated a little higher than what you are looking for so you have a bit of a buffer in case your circumstances change.

Of course if you think you will be adding more appliances as time goes on then it is worth buying an inverter with a decent amount of headroom otherwise you might end up having to buy another power inverter just to keep up with your power requirements. To help you work out how much power you will need we have put together a power inverter selection guide with a listing of common appliances and their power requirements so you can pick the right power inverter for your needs.
