Abstract

The invention discloses a household hybrid power supply management system and a power supply management method. The hybrid power supply management system comprises a utility power input circuit, a photovoltaic panel and a storage battery. The hybrid power supply management system is characterized in that the photovoltaic panel is connected with the storage battery through an MPPT (Maximum Power Point Tracking) controller and a DC chopper which are connected in series; the storage battery is connected with a photovoltaic controller and is connected with an inverter circuit through a charging and discharging system; the photovoltaic controller is also connected with the MPPT controller; the utility power input circuit is connected with an utility power output control circuit which is connected with the photovoltaic controller; the inverter circuit is connected with an isolation transformer; and the utility power output control circuit and the isolation transformer are connected with an AC output interface. The system provided by the invention supplies electricity in the manner of integrating photovoltaic power, utility power and the storage battery together, has a logic control function, and outputs a pure sine wave through an inverter. In addition, the system has a voltage adjustment function and outputs stable voltage.

Description
