Abstract

The invention discloses a photovoltaic module data communication method and system and a photovoltaic module device, and belongs to the field of photovoltaic technology. According to the technical scheme provided by the embodiment of the invention, the photovoltaic module device sends module-level information, including data packets of voltage, current, power and temperature operation state parameters, to an adjacent photovoltaic module device through a Bluetooth module, so that the data are sent, relayed and received in a network layer, then proxy is carried out through a Bluetooth gateway, finally, different communication modes (including but not limited to RS485, 4G, 5G, NB-IoT, LoRa, wifi and Bluetooth mesh networking) suitable for field installation are adopted, and required specified messages are issued on an energy management platform. The information acquisition and manual operation and maintenance cost of the photovoltaic module device is greatly reduced, the problem that the current photovoltaic new energy direct current side informatization is short in the last one kilometer is effectively solved, 100% transparency of power station performance and functions is achieved, and therefore the operation and maintenance efficiency of a photovoltaic power station is improved.

Description
