BIPV PV Building Integrated Photovoltaic system together with Photovoltaic system

摘要

When using the present invention, in one energy management system, a photovoltaic (PV) module and a building integrated photovoltaic (BIPV) module are integrally controlled and managed. When using the present invention, reverse current between the PV module and the BIPV module can be prevented. In an arc blocking unit, the present invention can detect and block an arc which occurs due to a problem in the PV module and the BIPV module. After the present invention detects and blocks the arc in the arc blocking unit, the energy management system receives a signal from an arc tracking unit and finds out which PV module or which BIPV module providing a cause of occurring the arc.
