Abstract

The application discloses a photovoltaic building integrated system comprising a control unit, a photovoltaic power generation unit, an energy storage unit, a photovoltaic inverter unit, and an energystorage inverter unit. The photovoltaic power generation unit, the energy storage unit, the photovoltaic inverter unit, and the energy storage inverter unit are connected with the control unit. The photovoltaic power generation unit is used for converting the solar energy into the electric energy, providing power for a load by the photovoltaic inverter unit, and / or storing the power into the energy storage unit. The energy storage unit includes one or more groups of energy storage battery modules; and each group of energy storage battery modules is used for storing the power generated by thephotovoltaic inverter unit and providing power for the load by the energy storage inverter unit. The control unit is used for selecting one from multiple power supplies for powering the load accordingto states of the photovoltaic power generation unit and the groups of energy storage battery modules and controlling the photovoltaic power generation unit to charge a storage battery module. The multiple power supplies include photovoltaic power generation parts and each group of energy storage battery modules. According to the application, the residual power generated by the photovoltaic powergeneration unit can be stored into the energy storage battery modules, thereby ensuring the continuity of power supply of the BIPV system.

Description

technical field [0001] The present invention relates to but not limited to the technical field of photovoltaic products, and in particular relates to a building-integrated photovoltaic system. Background technique [0002] Building Integrated Photovoltaic (BIPV) technology is a technology that integrates solar power (photovoltaic) products into buildings. In modern society, people's pursuit of a comfortable building environment is getting higher and higher, which leads to the increasing energy consumption of building heating and air conditioning. BIPV organically combines the solar photovoltaic power generation system with the curtain wall and roof outside the building to form an integral structure. The building load is used, and the excess power can also be incorporated into the grid. [0003] The existing BIPV system can use solar power to generate electricity to solve part of the power consumption, but there is no energy storage device corresponding to it, there are sho...
