The amount of power you think you’ll need for your house during an outage is critical to picking the right generator. If you’re comfortable with just keeping the most vital components of your home running, you could get by with a generator with less power. But if you want full power as usual, you’re looking at bigger generators. A typical home needs around a 20,000-watt generator to power everything while a 5,000- to 7,500-watt generator can power items like a refrigerator, furnace and water.
Pay special attention to a generator’s starting watts rating and its running watts rating. Starting watts skew higher because they account for the extra power needed to start appliances. The fuel you’ll use to power a generator will likely be the same type as you use for your home because standby generators tap into existing gas lines. Propane gas runs more expensive than natural gas and has experienced shortages in years past, but propane is more efficient than natural gas. If you’re planning to tap into an existing gas line then the installation is pretty straightforward, however, it’s best to leave the work to a pro.
- Installation can get complicated depending upon the levelness of the spot you want the generator installed, possible building permits and the need for an electrician.
- AlltimePower suggests a rule of thumb for estimating installation costs for a generator to be about 75% of the cost of the generator.

If you don’t have a home generator yet, you need to get one pronto. A home generator is one of those things that you’d rather have and not need, rather than need and not have. But eventually you’ll find yourself in a position of needing one, when you have power outage at home. With a generator during a home power outage, you’re able to enjoy the following advantages:.
The generator can run the air conditioner in the summer and the heating system in winter.
It can keep the lights on in your home so everyone can move around safely and freely.
You’re able to use cooking appliances to prepare food.
If you’re rushing to do some work on your laptop or PC, the generator can make sure that you’re able to finish the job despite the power outage.

A portable generator is generally more affordable, can move easily anywhere you want and setup wherever you need. Basically, you won’t have to endure the lack of available electrical power even when there’s an outage at home or you’re outdoors where there’s no convenient wall socket to power your electronic devices. This capability is crucial in boosting your comfort levels, and in emergencies it can even save lives.
The size of the generator you need depends on all the appliances you want to power in your house. And if you want to power your entire house, you need to list out all the electrical appliances in your house. Sum up their amperages or wattages. That should give you an idea of the total wattage. Remember, it is possible for you to buy another electrical appliance after installing your generator.
For instance, you may purchase a bigger refrigerator several months or years after getting your generator.
So, you need to add extra wattage to the total wattage.
Some people believe that it may be a good idea to purchase a generator that can supply much more power than you need.
As far as we’re concerned, this is not economical.
The more the capacity of a generator, the more expensive it will be.
- So, why pay for additional wattage that you don’t need?
- Generally, a 3000-watt generator should be sufficient to power your house easily.
- This depends on certain factors, and the factors have been discussed right below.
Manufacturer’s recommendation: Some generators can run continuously for more than 12 straight hours, but the manufacturer recommends that you should allow the generator to rest after making it work for a certain number of hours. Fuel tank capacity: No matter how long your generator can work, it will shut down when it runs out of fuel.
So, the amount of fuel its tank can take plays a role in determining how long the generator will work. Amount of load: If you have been using generators, you’ll know that the more load you put on it, the faster it will consume your fuel. And when it runs out of fuel, it will shut down. This is why generators work longest when it’s on 25% load capacity.
That being said, backup generators work for about 6 – 12 hours, depending on the factors discussed above.
Also, some generators can work longer than 12 hours.
Remember, most of the appliances we use at home are powered by electricity.
The TV, air conditioning unit, heating unit, fans, microwave oven, pressing iron, washing machine, dishwasher, laptop, smartphone, and tablet all need electricity to function.
So, a power failure may be difficult to bear, even for a few minutes.
- Unfortunately, you can’t prevent power outages.
- You can only provide a backup power supply.
- That’s why a whole house backup generator is worth its cost and much more.
Get it if you can afford it. It all depends on the size and capacity of the generator. There are several generators that can power a whole house easily. However, such generators cost a fortune to purchase, and they also cost a lot of dollars to run because they consume a lot of fuel. Tesla Powerwall has several benefits over a generator and vice versa.
Powerwall is very quiet. It does not make noise like generators. Also, Tesla Powerwall has a mobile app through which you can monitor your power usage. Furthermore, it works with National Weather Service (NWS), so it can take actions based on the information it receives from NWS. For example, if there’s a report that a storm is coming soon, Powerwall will increase its power saving.
On the other hand, Powerwall is a battery attached to solar panels.
So, without solar panels, it cannot function.
This is the advantage generators have over it.
In addition, there are several brands of generators, and this gives buyers more options.
- Powerwall is made by only Tesla.
- So, if anything goes wrong with your Powerwall, it can only be fixed by Tesla.
