The title you see is a very common question that people ask while purchasing any generator. How big should the generator be for my use? Well, there are certain reasons behind this why people ask it. For portability and noiseless power, people prefer inverter generator. But this portability comes at a cost of more bucks. They are more expensive but usually produce less power than a conventional generator. Is the power generated by an inverter generator enough for my purpose? Well, we will look for the answer here in this article. This post is full of information and advice that will help you get the answer very clearly, what size of generator do you need.
Before we proceed, some tips for you. Bigger is not always better. Most of the buyers will prefer having a more powerful motor considering that a better decision. Not necessarily. What you need to do is to measure if the generator can fulfill your power requirement, if that can, that is the best generator for you. To handle and maintain a bigger generator might be really troublesome sometimes. It’s difficult to carry from one place to another, and there are other maintenance issues. They will cost you higher for some extra power that you are not going to need. So go through this article carefully and take the decision smartly.
What Is The Purpose of Buying A Generator?
The answer to this question mainly guides the answer to your previous question about the size of the generator. We use electricity for almost anything nowadays. So can power be excessive ever? Well, maybe not, because we will find a way to spend them. But generator of greater production capacity will cost you more for the extra power that might not be necessary. Why are you going to purchase a generator? What will be the use? To make it easier for you, let’s divide the use of a generator in three categories. One is for home use, one is recreational use and another one is emergency use.
Also, you need to figure out the power consumption of the tools and appliances that you will connect to the generator. Now here you need to do a bit of calculation. You need to know some easy technical term. The running watt is the amount of power that the appliance needs while running. The surge watt is the amount of power that is required while starting the tools. Surge watt is always greater than running watt. Follow the chart below carefully, you will get a pretty much clear idea about the calculation.
You will get the power consumption data on the packaging of your appliance. Most of the time, the measurement is in ‘amp’ instead of ‘watt’. You just need to multiply the amp with the volt to get the watt measurement. This is the running watt. Surge watt is normally 2/3 times more than the running watt. Appliances those feature an electric motor, like refrigerators, air compressors, air conditioners, well pumps, power tools, require more watts to start up. In general, the majority of the homeowners can support their appliances with a generator that produces power between 3500 and 6500 watts, while the exact answer varies and depends on the proper measurement.
Surge watt vs. running watt
Here I will talk about some technical specification to share a better idea on why appliances need more power to start. You may notice that not all the devices are same. Some needs extra power and some doesn’t need. Why is that? There are two types of electric loads. One is resistive loads and the other is reactive loads.
Devices of resistive loads require same amount of power to both starting and running. These devices do not feature a motor and there is no magnetic field involved. On contrary reactive loads needs more power to start than running. The examples of these devices are freezers, furnace fans, pumps, air conditioners, air compressors etc. They come with fan and once the device starts running the consumption of the power drop significantly. In general surge, watt is 2/3 times more than the running watt.
Right Size of Generator for A Power Outage
Power outage can take place for any natural calamity. In some areas there are frequent natural calamities and they can cause power outage for hours if not for days. A generator can support you and your family in this meantime. Foods stored on your refrigerator can be fresh or you can be comfortable running the AC until the power comes back in.
Just imagine what you need to run during any power outage, the refrigerator, the microwave, the radio and maybe some other essential appliances. In this case a 3000 watts generator can be good enough. If you want to run an AC, the power requirement will be increased and you need more wattage. If there are serious calamities like hurricane and that causes power outage for days, you need to be more calculative. Because a generator will not provide you power forever. You need to have a powerful generator with a manual switch to deal with such difficult situation. And make sure that you use only appliances that are very important like water heater, microwaves etc.
Right Size of Generator for Recreational Purposes
A generator can be a great source of power while you are on an outing like camping, picnic or any other activities. Traditionally a camping generator is really noisy and that disturbs the neighborhood. Since the inverter generator is much less noisy, it has been very popular nowadays. While outing you may need the power to use the coffee maker, electric grill, recharge the phone, maybe the laptop. For this reason, a small portable inverter generator between 1000-2000 watts can be perfect.
But if you are camping in a recreational vehicle (RV) and you need to run the rooftop AC for more comfort, maybe a small refrigerator as well, a small television and a microwave, you should get something between 2500-4000 watts.
Right Size of Generator for Whole House Backup
This is the most crucial time when you need to calculate more than any other situation. Calculate and find the power consumption of the whole house or at least the appliances that you want to run with the generator. Say, for example, the central AC unit, refrigerator, washing machine, dryer, water heater and some other small kinds of stuff, you should get something in between 10,000 – 18,000 watts.
Usually, if you do not want any power interruption there can be a standby generator at your home. There are generators of different power range; you just need to be smart selecting and measuring the power requirements. This varies a lot since the size of the house varies.
Right Size of Generator for Work
If you are a contractor or if you work in a construction area, chances are that there is not any power supply. You will need a generator there for electricity. Like all other cases, the size of the generator will depend on the size of the tools that you are running the site. For smaller power, a 2000 watt generator should be enough. But if you will need more power if you want to run an air compressor or an electric saw. You may consider having a generator of between 4000-6000 watts.
Once you got the right generator for you, make sure that you follow the proper safety policies to be safe. Never use your generator indoor, not inside a garage, carport, basement or in any other fully or partially enclosed area. Even if the place has ventilation, do not use indoor. Be safe, be sound!
