KOHLER KOH10DC-7600 Power Reserve Energy Storage System
Residential Energy Storage System
The KohlerR Power Reserve energy storage system can maintain power to critical items such as refrigerators, computers, TVs, lights, and garage doors when the grid goes down or for autonomous off- grid applications. The system can also provide automated cost saving through energy rate arbitrage and system power flow control.
