What Size Generator to Run a 2000 Square Feet House?

What Size Generator to Run a 2000 Square Feet House?

Maintaining a steady electricity supply within a 2000.sq.ft property might be a relatively hectic task. This is especially true if there are emergent power surges or the time you decide to use heavy energy-consuming appliances at the same time.  That's where a backup generator becomes indispensable for your home. But how would you realize what size of a generator to get? How do you estimate the make and fuel type of a generator that you need to buy for an emergency with your home estimated energy needs? What considerations must you take into account when deciding which one to purchase for your home?

We are going to address all such questions in our discussion below. We will lead you on how to look at the size of generators so that you know how much it will be sufficient for a 2000 square feet house based on what gallons of electricity consumption; of course, you have had a gauge idea and thus whatever you desire operating.

How to Size the Generator You Need?

Quite a number of processes precede getting to know in advance what the correct size of a generator would be for that house that measures 2000 square feet. First, you should be able to establish the total load by cataloguing which appliances among those wired must be powered when lights go off and what is each appliance's wattage requirement.

It's crucial to remember that certain appliances, such as refrigerators and air conditioners, demand more power to initiate than to operate, so your generator should be equipped to manage these power surges. To streamline this process, numerous generator manufacturers provide online sizing calculators. By entering your appliances and their wattage, these tools can propose a suitable generator size. However, these calculators should be used as a preliminary guide.

Even more accurate determination should be done on your premises by a qualified electrician or an expert in generator matters who can perform comprehensive load analysis for your residence, then advise on the size of a generator needed.

Types of Generator

Selecting the right setup for a 2000 square feet house will mostly be tied to the possible options of different types, each with its unique characteristics, benefits, and reservations.

  • Solar Generators: These environmentally-friendly energy solutions capture daylight power via photovoltaic collectors and transform it into electricity. They offer a sustainable option for home backup power and can significantly decrease your electricity expenses over time. However, they necessitate a considerable amount of sunlight and have a higher initial cost. Despite these hurdles, solar generators are an outstanding long-term investment, particularly for those dedicated to eco-conscious living.

  • Conventional generator: This is the one that uses gasoline as fuel, which is a famously accessible commodity given at all fuel stations. It comes in different sizes up to large ones, which can make it adaptable to various conditions, from minor application power sources to the backup needed in your whole household. However, they also need maintenance, produce noise with emissions, and add up over time due to the cost of fuel.
  • Propane Generators: While this sort of generator functions similarly to the most common automotive gasoline-driven models, it uses liquid propane gas instead. It is much cleaner burning, quieter, and has a much longer life compared to most other generators simply because the fuel it uses has a much longer shelf life and is safer. The downside is that they are more expensive to buy up front and provide lesser power compared to a traditional gas generator.

Effectively, one's choice depends largely on preference and specific needs. In that case, go for a solar generator if your first priorities are sustainability and cost-effectiveness in the long run. If, on the other hand, it is a sure source of instant power you need, then go for a gas generator. And if quietness and cleaner energy issues count with you, then opt for a propane one. Then remember, the most suitable generator for a 2,000 square feet house is the one with much efficiency and reliability in power delivery.

How To Calculate Your Home's Electricity Use?

The understanding of how much power your home consumes will help ascertain the setup you need for a generator. Here's a simple guide to help in building up an accurate calculation for energy consumption for your house.

  • Step 1: Collect The Bills

You should collect all the electricity bills from last year. They are supposed to show monthly units of electricity consumed (kilowatt-hours/kWh).

  • Step 2: Calculate Average Monthly Use In kWh

Subtract the initial reading from the final reading to get your total kWh. Sum up all the individual totals in each month and divide by 12. This is your average monthly electricity.

  • Step 3: Take Seasonal Differences into Account

Your electricity consumption may vary throughout the year due to heating or cooling demands. If this is the case, compute separate averages for high and low usage seasons.

  • Step 4: Find Your Daily Consumption

Then you divide your monthly average by the number of days in a month for you to obtain your daily consumption.

  • Step 5: Plane According To Generator Capacity

With the computed value showing just how much electricity you blow in kWh every day, it won't be hard to determine the size of generator needed. If need be to power all electrical tools in your house when lights go out, just look for a generator that will at least produce the same number of kWh that you consume any other day.
