<p>An energy saving device for peak and valley power supply of a power grid. When the device is in the valley period of nighttime power supply, a power source (1) is in contact with a charger (4); the charger is connected to a storage battery (5); the storage battery is charged with stored energy; and the storage battery is connected to an inverter (6). When the device is in the peak period of daytime power supply, the direct current of the storage battery which is charged with stored energy at night is converted through the inverter into alternating current commercial electric supply for use. The charger is connected to a controller (3), and the storage battery is connected to a detection device (9) and a battery life-extension device (10). The device not only saves energy, but can also bring certain economic benefits.</p> |
