Home appliance innovator Kohler just unveiled its new range of home batteries. The off-grid power system is modular, offering three different sizes of battery pack:10 kWh, 15 kWh, and 20 kWh, which can be combined to custom-fit your power needs and your home. Like Tesla’s Power Wall, these batteries are designed to support a solar array, banking power for use when none is being produced. They can also work as backup with your regular power-grid connection.
