Title:
CONTROL MODULE AND SYSTEM CAPABLE OF REALIZING DOMINO TYPE AUTOMATIC SNOW MELTING OF PHOTOVOLTAIC MODULES
Document Type and Number:
WIPO Patent Application WO/2020/248482
Kind Code:
A1
Abstract:
A control system capable of realizing Domino type automatic snow melting of photovoltaic modules, comprising a controller, M photovoltaic modules and a photovoltaic power supply control module; when a photovoltaic assembly connected to the k-th photovoltaic interface is in a load mode, photovoltaic assemblies connected to the first to the (k-1)th photovoltaic interfaces supply power to the photovoltaic assembly connected to the k-th photovoltaic interface, 2 ≤ k ≤ M. The M photovoltaic assemblies are correspondingly connected to the M photovoltaic interfaces of the photovoltaic power supply control module; the controller is connected to the photovoltaic power supply control module and is configured to control a working state of the photovoltaic power supply control module. Said system achieves the Domino effect by gradually increasing the power supply amount, facilitating improving snow melting efficiency, reducing snow melting time, and improving the working time and power generation benefits of photovoltaic power generation of a roof photovoltaic power generation system in a freezing season.
