Can a Solar Generator Power a Whole House?

Sustainable living reduces energy consumption helping reduce your carbon footprint. And one way to go about it is to install a whole house solar generator. They are eco-friendly, quiet, and compact. But can they power your entire house? Let’s find out.

Can a Solar Generator Power a Whole House?

Yes, a solar generator can power your entire house. That said, it depends on factors such as energy consumption, house size, and the size of the generator. Generally, whole house solar generators are equipped to produce ample energy to power all appliances in your house.

For example, a 2000-watt generator will adequately power the whole house with ease. The location of your house can also affect the power output of the solar generator. As you know, solar products are dependent on the amount of sunlight. So, when choosing a generator for your house, consider this aspect.

A typical solar generator will consist of solar panels, solar batteries, an inverter, and other systems to bolster its efficiency. And the amount of power it can capture will depend on the efficiency, rated power, and installed PV panels. 

Depending on the number of appliances you’ll be running, you might need to supplement your solar generator with another source of power such as the grid. Alternatively, you can use a backup generator. 

So, can a solar generator power your house? Yes, in fact, large BLUETTI solar generators are the most ideal since they are high-capacity generators.

What Size Solar Generator Do You Need to Run a House?

You’ll need to consider the energy consumption of your household when choosing the size of a solar generator. While a typical American household consumes at least 30 kilowatt-hours of electricity daily, you should calculate your individual consumption rate.

Calculate Your Average Power Consumption

One of the best ways to estimate the size of solar generator you need is to calculate the average power consumption. Fortunately, you can get this information from your monthly electricity bill.

Since electricity consumption varies from month to month, you can use an average of 6 months to calculate a more accurate average. However, if your focus is provision of power during blackouts only, you might not need to calculate your average energy consumption.

Determine Wattage Requirements 

To get the right size of solar generator, you’ll need to calculate the wattage requirements of your appliances.

Small appliances will only have a running wattage requirement. Larger appliances will have starting and running wattage ratings. The ratings are labeled on the appliances. Here are wattage requirements of the most common appliances.

Appliance

Running (Rated) Watts

Starting Watts 

Washing machine

1200

2300

Refrigerator 

700

2200

Microwave 

1000

0

Dishwasher 

1300

1800

TV

500

0

Laptop 

50-300

0

Light bulb

40-75

0

If the power rating is in volts or amps, you can convert it into wattage using the following formula:

Volts (V) x Amps (A) = Watts (W)

Now, you can add all the running wattage of the appliances the generator will be running. Is the total less than the rated wattage of the solar generator? If so, that’s an ideal option. Otherwise, you’ll need to buy one with a higher rated wattage.

You should also consider the appliance with the highest starting wattage. Pick the highest starting wattage and add it to the total running wattage. You now have the total starting watts you need from your generator. 

Ensure the starting wattage of the generator is higher than that of the appliances to avoid overloading it. 

With this info you can now determine the inverter size, battery capacity, and the number of solar panels you’ll need. 

Ideally, the inverter should be at least 120% than the total wattage requirements. For example, to run a household with a 4000W rating, you’ll need a 4600W inverter.

The capacity of the solar batteries should be twice your energy consumption. If your total consumption is 5000W per day, you’ll need batteries with a total capacity of 10000Wh. 

Finally, to determine the number of solar panels, you’ll need to factor in the panel capacity, storage capacity of your batteries, and the number of peak sun hours. 

You’ll need to divide the battery’s storage capacity by the product of peak sun suns and panel capacity.

So, if you have a battery with a capacity of 10000 Wh, 5 peak sun hours, and 400W, you’ll need 5 solar panels.

How to Choose the Best Whole House Solar Generator?

Now that you know how to calculate the size of a solar generator, how then do you choose the most ideal for your needs? Let’s find out.

Battery lifespan

The lifespan of a solar generator is among the most important aspects you should consider. You don’t want to buy one that will last a few years. This means you need one with a longer battery lifespan. And the best option are those that are equipped with LiFePO4 batteries. They can last for 10 years while offering excellent storage capacity. 

Cost 

While you should buy a solar generator within your budget, you should not always go for cheaper options. Most are knock offs with inferior or no safety features. If possible, buy a whole house solar generator priced from $5000. 

Not only are they of high quality but also come with much-needed features and warranties. For the best value for your money, you might consider buying from brands such as BLUETTI.

Type Of Inverter

You should also consider the type of inverter. The best option is the Pure Sine Wave (PSW) inverter that is compatible with all household appliances. Besides, they have a high output. 

Recharging Options

You want to buy a solar generator that has different ways of recharging it simultaneously. Ideally, you should opt for one with two or methods. This reduces the recharging time and allows you to use different power sources. Take, for example, the BLUETTI AC200MAX that can recharge using solar, AC, and lead acid batteries.

Scalability 

Besides its capacity, you’ll need a generator that is expandable. Energy needs change and your generator should accommodate these changes. Choose one that is compatible with expandable batteries. Most BLUETTI solar generators allow you to expand their capacity using extra batteries.
