There are a lot of perks to at-home batteries: they have your back during an outage, can help manage solar energy if you have panels, and can even top off your electric car.

Combined with advancements in solar technology, these large batteries have the potential to provide a whole new way to store and control the energy used in your home.

It's for that reason that an increasing number of companies are working on at-home batteries to change the modern home into a sustainable vision for the future.

Here are nine at-home batteries on the market today.

We would be remiss to make a list of at-home battery makers and not include Tesla toward the top. The $3,500 Powerwall can store solar energy and provide backup power for your home.

At roughly 200 pounds, Tesla's lithium-ion battery can connect to the internet to create "smart microgrids" that could potentially power a home off the grid entirely.

The Powerwall supplies 6.4 kWh of power. To help put that into perspective, the average person in the US uses about 30 kWh of power a day.

Tesla says on its website that the 6.4 kWh battery is sufficient to power most homes during the evening using the solar energy captured during the day. However, multiple batteries can be installed in homes that need more energy.
