The Mercedes at-home battery has been highly touted for a while now but unlike Tesla’s battery, the cost of the device has not been revealed.
A Mercedes spokesperson has now told Tech Insider that “the unit for a standard family home costs between $9,000 and $10,000, including the price of the inverter and installation.”
Mercedes launched its battery in 2015 in Germany and the company plans to roll out the device to other European markets, like the Netherlands and Switzerland.
The at-home battery weighs 66 pounds and stores 2.5 kWh of energy. Customers can stack up to eight units for 20 kWh of storage.
The average home in the US uses 30 kWh per day.
In comparison, Tesla’s 200-pound Powerwall stores up to 6.4 kWh of energy and can be stacked with nine units for 58kWh worth of energy capacity.
A single Powerwall unit costs $3,000 with a total cost of $7,000 when including the cost of installation and an inverter, according to a Bloomberg report.
There are other companies that are also offering at-home power units. Nissan recently announced its xStorage unit which costs $4,500 for 4.2kWh of energy storage and that includes the price of installation.
A new start-up called Orison is also creating a 40 pound unit that holds 2.2 kWh of energy and can stack five panels for a total of 13.2 kWh of power.
