Introducing KOHLER Power Reserve, an energy storage system that keeps your home powered during an outage—and provides energy independence from the grid. For homes with solar panels, Power Reserve stores the solar energy gathered throughout the day and reserves that energy for use whenever you want it. Think of it like an energy bank account where you can make deposits and withdrawals as you see fit.
Power Reserve is comprised of a battery and inverter—and is able to work with both AC and DC electric circuits. These components can be installed indoors (e.g., your garage) or outdoors (e.g., side of the house). And the best of all, Power Reserve is compatible with ANY solar panel installation.

Energy Storage System – Simplified: KOHLER Power Reserve energy storage system is comprised of a long-life LiFePO4 battery, inverter, and optional automatic transfer switch (sold separately). We have three outdoor-rated battery options (10, 15, 20kWh providing up to 7.6kW of maximum power output) to choose from to meet your power needs. And all three feature a modular design which allows them to be customized for even greater power storage and installation flexibility.The Power Reserve system stores energy from solar panels to be used whenever you want, which means you can use your stored energy to power your home during an outage. Or you can use your stored energy as your primary power source to reduce your dependence on the grid and lower your utility bills.
