The invention discloses an internet-based energy management system. The system includes an energy monitoring center and an energy monitoring station, the energy monitoring center includes a central processor, an output end of the central processor is electrically and bidirectionally connected to a control platform, and the output end of the central processor is electrically and bidirectionally connected to a data storage module. Through mutual cooperation of the arranged central processor, the control platform, the data storage module, a first signal transmitting-receiving module, a CPU, a second signal transmitting-receiving module, a feedback module, an electric energy acquisition module, a large storage battery pack, a wind generating set and a solar photovoltaic array, the system achieves the advantages of being convenient for a manager to monitor and manage energy, and solves the problem that an existing energy management system is not convenient for the manager to monitor and manage the energy, when people use the energy management system, people can know energy power storage condition in time, the energy management system is convenient for the manager to reasonably distribute energy and is convenient for people to use.
