A generator is an essential backup power source for a home during a power outage.
The size of the generator is crucial to ensure providing power to all the necessary appliances and systems in the house.
When it comes to a 2000 sq ft house, there are specific factors to consider when choosing the right generator size.
In this outline, we will discuss the factors to consider and recommend the appropriate Generac generator size for a 2000 sq ft house.
what size generac generator for 2000 sq ft house
For a 2000 sq ft house, a Generac generator with a capacity of 12kW to 16kW is recommended.
A 12kW generator can power like lighting, refrigerator, and furnace, while a 16kW generator can handle larger systems like a well pump or a larger HVAC system.
See the table below for a summary of recommended Generac generator sizes for a 2000 sq ft house.
| Wattage Requirements | Recommended Generator Size |
|---|---|
| Up to 8,000 watts | 10-12kW Generac Generator |
| Up to 12,000 watts | 14-16kW Generac Generator |
| Up to 16,000 watts | 18-20kW Generac Generator |
Determining Power Requirements
Determining the wattage requirements for a generator is essential for powering all the necessary appliances and systems during an outage.
Here are the steps to determine the power requirements for a 2000 sq ft house:
Make a list of all essential appliances and systems
Make a list of all essential appliances and systems, including the wattage for each item.
Check the label on the appliance or its user manual. Essential appliances for a home include the refrigerator, HVAC system, well pump, security system, and lighting.
Make a list of all the appliances and systems and note their wattage ratings.
Determine the starting wattage for each item
Some appliances require more power to start up than they do to operate.
To determine the starting wattage for an appliance, check the user manual or contact the manufacturer. Note the starting wattage for each appliance on the list.
Add up the wattage for all items and multiply by 1.5.
Once you have the wattage rating for each appliance and system, add them all up.
Multiply the total wattage by 1.5 to account for the surge wattage needed when appliances start up.
For example, if the total wattage for all items is 8000, then the required wattage for the generator is 12000.
Determine if any items can be powered off
After calculating the required wattage, consider if there are any non-essential items that can be turned off during an outage.
This can help reduce the required generator size and potentially save money.
For example, non-essential lighting or entertainment systems can be turned off during an outage to reduce the total wattage required.
Consider any potential future additions
If there are plans to add new appliances or systems to the home in the future, consider the wattage requirements of these items.
This can help ensure that the generator size chosen is sufficient to handle any future additions.
Types of Generators
There are several types of generators available in the market with their own benefits and drawbacks.
Here are some of the most common types of generators:
Portable Generators
Portable generators are designed for easy mobility and are ideal for temporary power outages or outdoor activities.
They are fueled by gasoline or propane and come in a variety of sizes, ranging from small units to larger models.
Portable generators are loud and emit harmful fumes, so they should be used in a well-ventilated area.
Standby Generators
Standby generators are permanently installed outside a home and connected to the home’s electrical system.
They are designed to automatically turn on when a power outage occurs and can provide uninterrupted power until the utility power is restored.
Standby generators are powered by natural gas or propane and can be more expensive than portable generators.
Inverter Generators
Inverter generators use advanced technology to provide clean, stable power.
They are smaller and quieter than conventional portable generators and are ideal for powering sensitive electronic devices.
Inverter generators are more expensive than conventional portable generators but are more fuel-efficient and produce fewer emissions.
Solar Generators
Solar generators use solar panels to convert sunlight into electricity and are a renewable energy option for homeowners.
They are portable and use for camping or outdoor activities, but can also be installed on a home for backup power. Solar generators require sunlight to generate power.
Wind Generators
Wind generators use wind turbines to convert wind energy into electricity and are another renewable energy option for homeowners.
They are installed on a tower and can provide backup power to a home.
Wind generators require strong and consistent wind to generate power, but they are not suitable for areas with low wind speeds.
Benefits of Choosing the Right Generator Size for a 2000 Sq Ft House
Choosing the right generator size for a 2000 sq ft house can have several benefits, including:
Cost Savings:
A too small generator is not able to power all the essential appliances and systems in the house, requiring homeowners to invest in a larger generator or make do without power for some systems.
A generator that is too large is more expensive to purchase and maintain, as well as consumes more fuel than necessary.
Choosing the right size can help homeowners avoid unnecessary expenses.
Comfort:
A properly sized generator ensures all essential systems and appliances in the house continue to operate during a power outage, providing comfort and convenience to homeowners.
This includes keeping the lights on, heating and cooling systems running, and powering medical equipment.
Safety:
Inappropriate size generators can pose safety risks to homeowners.
They can also overload and overheat, causing a fire hazard, while a generator that is too large can create excess noise and vibration damaging the home’s structure.
Choosing the right size can help ensure the generator operates safely.
Reliability:
A proper size generator can provide reliable backup power during a power outage, ensuring homeowners are not left without power for extended periods.
This prevents damage to appliances and systems from occurring when power is abruptly cut off.
Installation and Maintenance
Installing and maintaining a generator is essential to ensure it operates safely and efficiently. Here are some key steps to consider for installation and maintenance:
Installation:
Determine the best location for the generator:
It is important to choose a location that is easily accessible for maintenance and repairs, while also being away from windows, doors, and vents to avoid carbon monoxide poisoning.
Install a transfer switch:
A transfer switch is essential for connecting the generator to the home’s electrical system and ensuring that power is properly distributed.
Install a fuel source:
The generator will require a fuel source such as propane or natural gas, which will need to be connected to the generator by a professional.
Hire a professional electrician:
Installation of the generator and transfer switch should be done by a licensed electrician to ensure it is done correctly and safely.
Maintenance:
Perform regular inspections:
Check the generator for any signs of wear and tear or damage, and ensure that all components are functioning properly.
Change the oil and filters:
Follow the manufacturer’s recommended schedule for oil and filter changes to ensure the generator operates efficiently and reliably.
Test the generator:
Test the generator regularly to ensure it starts up and operates properly in case of a power outage.
Keep the area around the generator clean:
Clear debris and vegetation around the generator to ensure proper ventilation and prevent damage to the unit.
Hire a professional for maintenance and repairs:
Regular maintenance by a licensed technician can help identify and address any potential issues before they become major problems.
