Expandable solar generators for home backup

Solar energy can power your entire home and save you money on electricity bills. Solar generators are an efficient way to generate clean electricity for your whole house, providing reliable power even when the grid is down. Learn more about these solar generators and discover how they can help you stay powered up and eco-friendly.


As a homeowner, it is important to have a reliable source of power in case of emergencies or power outages. Solar generators are a great option for providing backup power, as they can be charged through solar panels and used to power a variety of


Three best power stations for home backup

All of these power stations have: capacity of at least 2,000Wh, and the option to charge up in several ways, including the use of multiple solar panels. 

For this guide, we have also focused on expandability. This refers to the ability to add more battery capacity and additional solar panels to increase the capability of the system. 

Maybe you foresee a larger need as your family grows, or budget constraints may guide you toward starting with a more basic system.  Or you may find that you need  larger capacity for a specific need at some point down the road.

Regardless of the reason, having the option to increase the capacity of the solar generator over time gives you more flexibility and choice.

Can you power your house with a battery? Is there a lithium battery that can power a house?

With natural disasters on the rise, an increasing number of homeowners are turning to battery backup systems as a dependable way to keep their homes powered. The EcoFlow Delta Pro and Mango Power E store energy generated by either home solar panels or the electrical grid, providing emergency power even when power is out.

How big of a battery backup do I need for my house? How many batteries do you need to run a house on solar?

To determine the size of the battery backup you need for your home, you'll need to consider a few things:

  • How much power does your home use on a daily basis? You can find this information on your electric bill.
  • How long do you want the battery backup to power your home? The longer you want the battery backup to last, the larger the battery capacity you'll need.
  • What appliances and systems do you want to power with the battery backup? Some appliances, like refrigerators and sump pumps, use more power than others, so you'll need a larger battery to power them.

Once you have this information, you can estimate the size of backup you need. Or reach out to the PowerMy.com team and we can help design a system that makes sense.

Is there an alternative to a whole house generator?

A battery backup system is an alternative to a whole house generator. A battery backup system is charged by your home's electrical system or by solar panels and can provide power to your home during an outage.

Battery backup systems are typically smaller and quieter than whole house generators, and they do not require fuel to operate. However, they may not be able to power as many appliances or for as long as a whole house generator, depending on the size of the battery system and the power needs of your home.

Another alternative to a whole house generator is a hybrid generator system. A hybrid generator is a type of generator that can operate on multiple fuel sources. For example, a hybrid generator may be able to run on gasoline, propane, or natural gas. Some hybrid generators can even run on renewable fuel sources, such as biofuels or solar power.

How much does a whole home battery cost?

The cost of a whole home battery system can vary widely, depending on the size of the battery, the type of battery, and the installation costs. On average, you can expect to pay between $5,000 and $20,000 for a whole home battery system.

However, based on the updated Solar Investment Tax Credit (ITC), you may be eligible for a 30% credit on your federal tax return when you file next year. So a $10,000 system would reduce your tax bill by roughly $3,000.

How do I power my house during a power outage? How can I power my house without electricity?

If you are trying to power your home during a power outage, there are several options you can consider:

  • Generator: A generator is a mechanical device that converts fuel into electricity. You can use a generator to power your home by connecting it to your home's electrical system. Make sure to follow proper safety precautions when using a generator.
  • Battery backup system: A battery backup system consists of a group of batteries that are charged by your home's electrical system and can provide power to your home during an outage.
  • Portable power station: A portable power station is a battery-based system that can be used to power small appliances and devices during a power outage.
  • Solar power: If you have solar panels installed on your home, you may be able to use them to generate electricity during a power outage. The electricity can be stored in batteries and used to power your home.
