Abstract

Provided is a system for controlling photovoltaic strings to perform Domino-type automatic snow melting, including a controller, M photovoltaic strings and a photovoltaic power supply control module; the 1st to (k−1)th photovoltaic strings supply power to the kth photovoltaic string, in response to the kth photovoltaic string being in a load mode, 2≤k≤M. The M photovoltaic strings are correspondingly connected to 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 the working state of the photovoltaic power supply control module.
