Your monthly energy bills can get quite expensive, especially during the summer. You need lots of energy to stay cool and power your electronics, but buying your energy from an outside company isn't always the most efficient or cost-effective.

That's where at-home batteries come in.

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's 9 at-home battery makers 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 $3,000 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.


Start-up Orison is an at-home battery system that comes in form of a plug-in unit that looks like a lamp and a flat wall panel that weighs just under 40 pounds.


The $1,600 unit holds significantly less power than the Tesla Powerwall (2.2 kWh versus 6.4 kWh). However, the main perk to Orison is you don't need a trained electrician to install it.


Powervault is an at-home battery system only available in the UK. The most powerful model allows for 4 kWh of energy and costs around $4,500.


Like the Tesla Powerwall, the Powervault must be installed by a trained electrician. But unlike Tesla's at-home battery, the inverter and control unit are included in the Powervault's $4,500 cost.


SimpliPhi Power is an at-home battery maker that's been around since 2002 — its original name was LibertyPak Company. They offer four different battery options, each with different energy saving abilities.


Their most powerful model is the PowerBank, which delivers 5.2 kWh of power. It needs to be installed by an electrician and offers off-grid applications.


The company has never publicly disclosed the cost of a unit and did not reply to multiple requests for comment.


Sunverge offers battery systems providing anywhere from 6 to 23 kWh of energy storage. Weighing around 500 pounds, the battery has to be installed by a trained Sunverge specialist.



The app is sold separately.

Mercedes sells an at-home battery in Germany, but has plans to expand internationally. Each unit stores 2.5 kWh of energy, but you can combine eight units for 20 kWh of storage.


You can track energy storage on a corresponding app. A standard family home costs between $9,000 and $10,000, including the price of the inverter and installation.


ElectrIQ is creating a battery for US homes that stores 10 kWh of energy. It requires installation from an electrician, but unlike the Powerwall the inverter is included.


It also comes with an app so you can track its energy storage. It will be available in late 2016. Its retail price is $13,000.


Panasonic's at-home battery can store 8 kWh of energy. It's currently available in Australia, but Panasonic plans to roll out the battery in Europe.


The battery weighs about 185 pounds. The cost of a unit is not made readily available.


Nissan offers a rechargeable battery option, called XStorage, which holds 4.2 kWh of energy storage. The automaker will begin taking pre-orders in September, and it will only be available in Europe.
