Storm coming and wondering how long can a generator run? Not sure how much fuel to get for standby time?
On average a regular portable full size generator of 5500 watts or larger can run on not load or very little for up to 11 hours on a tank. This decreases greatly the harder the unit runs and the more power it produces. At have load runtime would be about 6 hours and under full load only 3 hours.
Plan accordingly for your power outage and have extra gas jugs on hand. Especially if you are caught in a snow storm and can’t make it to the fuel station.
1.How Long Can A Generator Run (Gas)
You can run a gas generator as long as you need too, providing you keep refueling and keep it cool. Most times a few hours is all you will need to get through a storm. Make sure you keep the generator in a well ventilated area if you plan to run it hard.
How long can a generator run (Propane)
A propane generator will run for up to 24 hours depending on the size of the propane tanks. This will depend on the age, condition and load put on the generator. Most portable generators are 5500 watts or larger. Each gallon of propane is equivalent to about 1.3 kilowatt hours.
Larger propane generators have tanks of larger size usually 200 gallon tanks of more. Depending on usage some tanks can give longer standby times.
How long can a generator run (Diesel)
You can run a diesel generator on furnace oil, but it’s not recommended. Generators are designed to run on diesel fuel because diesel contains additives that prevent it from thickening during cold weather. Furnace oil does not contain these additives and may cause the engine to stall or seize up when used in cold weather.
If you must use furnace oil, consider running the generator at lower power levels until it warms up. Once the unit is warmed up, try increasing power slowly to no more than 25 percent of what you would normally use with diesel fuel. Make sure to watch out for warning signs of problems like smoke or an unusual smell coming from the generator. Again not recommended.
Can a portable generator run 24 7?
No. Portable generators are designed to run for a few hours, not days on end.
That said, there are generator systems that can be installed permanently at your home or work site that will provide you with the power you need 24/7 anywhere you have electric service.
Generator systems are available in many different sizes depending on your needs and budget. Make sure to do your research before making a purchase decision so you know what size generator system is ideal for your home or business.
Can you run a house on a generator full time
We must first understand what we are trying to achieve by running a house on a generator. A house is not just lights and TV. A house also has central heating and air conditioning, refrigerators, washers and dryers, dishwashers, ovens and microwaves etc.
If you want to run these items on a generator full time you will need at least 10kw of power. This is the equivalent of running two huge refrigerator/freezers plus all the other items in your kitchen plus everything else in your home that needs electricity.
At this point you would be wise to invest in a larger generator than the 5500 watt portable type. You may also need an electrician to adapt your electrical system for off-grid use as well as some solar panels and charging units for your batteries. This is not something most people can do themselves or afford to do without some help from friends or family with experience.
Should you run a generator overnight?
The short answer is no. Running a generator 24/7 can damage the engine and reduce lifespan and power output.
While there are some exceptions, the best practice is to only use a generator for an hour or two at a time until you need it again. This will ensure your machine will last longer and produce more usable power.
Let’s say we don’t get any snow this winter but get an ice storm instead. You’re staying in your house to wait out the storm and it’ll be days before your power comes back on. You might need to run a generator for an hour or two just to keep you warm and cook food while waiting for the utility company to turn the lights back on.
This means you could start and stop your generator every day, if necessary, with no long-term damage to your machine.
How long will whole home generator run?
A whole home generator is a great way to keep your family safe during a power outage. It will keep the essentials running if the power goes out for an extended period of time, so you have peace of mind.
A whole house generator runs off natural gas or propane and can power entire homes, including appliances and HVAC systems, as long as it has enough fuel supply. The average whole house generator will run for about 24 hours on one tank of gas.
So, how much fuel do you need? To determine how much fuel you need to buy, multiply the watts for your home by 8 hours (the estimated runtime). For example, a 3100 watt home would be calculated as follows: 3100 watts x 8 hours = 25600 watt-hours.
Multiply this number by the price per gallon of fuel and divide by 60 minutes to get the cost in dollars.
Is it OK to let generator run out of gas?
A lot of people who own generators ask this question.
Some will say that it is better to let the generator run out of gas because once it starts to sputter, it is time for a refill.
Others may argue that it is better to fill up the tank before you run out so you can keep on running.
There are advantages and disadvantages to both options. If you let the generator run out without refueling, at least you know where your fuel level is and can plan accordingly with a full tank if necessary. The disadvantage of this option is that when the unit starts to sputter, you have no power until you start filling up again – potentially leading to a longer outage time.
On the other hand, if you have a full tank before the generator runs out, then when the engine begins sputtering, this means your battery will drain faster and may leave your home without power for a longer period of time.
Can you leave a generator running unattended?
It’s not advisable to leave a generator running unattended.
Most generators have a run time of 6 hours at half load, 3 hours at full load. If you are leaving your generator unattended for an extended period of time it is recommended to refuel the unit before starting.
There are also portable generators you can use with solar panels or wind power that are “smart” and automatically turn on when the battery power drops below a certain level. These units will turn off when power returns.
Will a generator harm electronics?
A generator will not harm your electronics. This is a myth that was started when generators were first introduced to the market. However if you run a generator out of fuel and it starts to sputter you can harm electronics We recommend to do the following to avoid this.
- Don’t let it run out of fuel
- Purchase a whole home surge protector and have it installed in the panel.
- Purchase an inverter driven generator.

Can you run a generator in the rain?
Portable generators are not designed to run in the rain. They are designed to be outside in the dry air and use fuel efficiently. The water will cool the unit quicker, thus using more fuel than normal. A generator that is in heavy rain can overheat and stop working before its fuel tank is emptied.
A generator with a carburetor will also need to be drained of water before it can be restarted if it has been running in the rain for any period of time.
It is always best to keep your generator dry, but if you live somewhere where there is high humidity or frequent precipitation, invest in an enclosure for your generator. It’s worth considering when purchasing a generator due to higher cost upfront.
How long should I run my generator for maintenance?
Generally you should run your generator once per week for 15 minutes.
Running your generator for maintenance is important to prolong the life of the unit. If you don’t, it may become damaged and start giving off white smoke when running.
A thirsty unit will start to produce white smoke if it isn’t well maintained. This is because the oil in the crankcase becomes too thin or too thick, which means that it can’t properly lubricate the engine parts.
You should also be sure to gas up the generator before storing it for winter. This will help keep moisture out of fuel tanks and prevent corrosion on electrical components.
Keeping your generator maintained will help keep you prepared when you need it most!
How much does it cost to run a whole house generator on natural gas?
The cost of operating a whole house generator is dependent on the type of natural gas you are using. Currently, it averages about $0.80 per hour to run a generator with natural gas.
How do you plug a generator into your house?
The generator should be plugged into a surge protector as well as a proper generator outlet to make sure it does not overload the household wiring.
How long can you store a new generator?
A new generator can store fuel for up to two years. Generally speaking, the shelf life of a portable generator is a little over a year.
You may want to keep your fuel in an outdoor shed to avoid corrosion and moisture, as these can affect the quality of the gas. If you have a generator that’s been sitting around for too long or it’s been exposed to humidity, you may need to drain and replace the gas before you use it again.
Also consider where you store your jugs of gas – if they’re inside, make sure your house isn’t attached to any other structures that could be easily damaged by a storm or flood. Keep them away from heat sources or direct sunlight – both will cause the fuel to age faster and deteriorate. Remember: It’ll cost more to replace a broken fuel tank than it will to just buy a new one!
