7.5kva Generator: What Will It Run?
KVA is the acronym for kilo volt-ampere. This is the unit for measuring the apparent power also called the electrical power of a power source. 1 unit of KVA equals 1000 volt-ampere. A 7.5 KVA generator can carry a lot of loads at the same time. It can even power an entire house.
You will find it to be reliable for powering your tools at the worksite too. It is trustworthy for those heavy-duty power jobs since it can generate a higher current than what you can find in smaller generates.
Such a generator can also feature several outlets for easy connection to electrical appliances.
What does generator wattage mean?
Generators come with two different power ratings, which are:
- Starting power
- Running power
The starting power can also be called the surge power rating of the generator. It represents the number of watts that the generator can produce for some seconds once it starts working.
You need to bear this in mind because many heavy-duty electrical appliances require more power when they want to start working; this is usually the case with motor-driven electrical appliances, like refrigerators, pumps, and power tools.
On the other hand, the running power rating is maintained by the generator after it has started working.
When connecting electrical appliances to your generator, make sure the sum of the power required by all the electrical appliances connected is not higher than the running power of the generator.
This will help to prevent overloading the generator, which can damage the latter.
7.5kva Generator: What Will It Run?
If you want to power most of the electrical appliances in your home, you can do this satisfactorily with a 7.5 KVA generator.
It can even work for a long time, thereby making it a good choice for an alternative power supply during a prolonged blackout.
After connecting many of your electrical appliances to the 7.5 KVA, there is a good chance that the generator will not be overloaded.
What is more, you can even connect an air conditioning system to the 7.5 KVA generators. However, its ability to power an air conditioner depends on the capacity of the air conditioner in question.
Central air conditioners can require between 3800 watts and 6,000 watts of power.
So, you should check the power rating of your air conditioner before connecting it to the 7.5 KVA generator.
A heating system does not need any starting power requirement and it will require about 5,000 watts of power to operate.
This means that the central air conditioner and the heating system can take up most of the power that a 7.5 KVA generator can produce.
The best thing to do when connecting a central air conditioner to the generator is to allow the temperature generated to stabilize before connecting any other electrical appliance.
If you need to run multiple electrical appliances in the home together with the air conditioning system, then you can opt for a window air conditioner or space heater.
This does not consume much power; studies show that they require about 1200 watts each.
This will make it very easy to connect several other electrical appliances to the 7.5 KVA generator.
Bear in mind that the window air conditioner requires 1800 watts starting power; always factor this in when running the air conditioner with your 7.5 KVA generator.
Many electrical appliances frequently used in the home should not require as much power as the air conditioners as a heater.
Your refrigerator, for example, will only require about 1200 watts of starting power and 700 watts of running power. Check below for a list of commonly used home appliances and their power ratings:
- Microwave requires 800 watts
- Toaster requires 850 watts
- A coffee maker requires about 800 watts
- The dishwasher requires about 300 watts
- A washing machine requires about 500 watts of running power and 1400 watts of starting power
- The dryer requires about 3000 watts
- Television requires about 400 watts
- The laptop requires about 300 watts
The incandescent bulbs will require 60 watts and LED bulbs to require 12 watts each. To save power, it is better to switch over to LED bulbs and quit using incandescent bulbs.
Do you use a well pump or sump pump in your home too? Then they too should be put into consideration. A pump will require about 1000 watts of power to run. Hoverer, its starting power can be 2000 watts to 3,000 watts.
How a 7.5 KVA generator can fair
Before we consider how well a 7.5 KVA generator can power your home, we need to put all the points mentioned above together first.
First of all, connect the lights, sump pump, and refrigerator to the generator; this should consume about 2000 watts of running power.
It will leave adequate space for connecting several other electrical appliances in the home, including the washing machine. If you want to run the dryer, you may have to disconnect a couple of other appliances from the 7.5 KVA generator.
After connecting the above appliances without the dryer, there will still be adequate space for connecting other appliances like the laptop and television.
Aside from the heater, all the other electrical appliances connected as described above will not amount up to 4000 watts of running power.
That extra power should be able to run your window air conditioner and space heater conveniently.
You can also use the 7.5 KVA generator to power several tools at the job site, including the following:
- Electric leaf blower requires 1000 watts of power
- Chainsaw bench grinder requires 1500 watts
- Bench grinder requires 2500 watts of starting power and 1400 watts of running power
- etc
Conclusion
From the above, it is obvious that your 7.5 KVA generator can conveniently provide adequate power for the essential electrical appliances in your home. You can get a lot of energy from a 7.5 KVA generator. It can power your home conveniently and also power many tools at your workshop, including a motor-driven tool even if the tool has a high surge requirement.
You can use such a generator to power the basic needs of your home and keep the interior comfortable. It will provide adequate power and you will not even feel as if power was taken in the first instance.
