Photovoltaic inverter health status monitoring and alarm system

Abstract

The invention relates to a photovoltaic inverter health status monitoring and alarm system which comprises an inverter monitoring system, a Zigbee networking module, a background server and a monitoring terminal. The inverter monitoring system collects the parameter and state information of a photovoltaic inverter and sends the data to the Zigbee networking module connected with a lower computer and sends the data to the background server through a wireless network to conduct data analysis and processing. The background server sends the working state evaluation of the inverter and the predicated service life of a key device to the monitoring terminal through a wired or wireless network or a GPRS network. Managing staff inquires the working state of the inverter through the monitoring terminal and sends control signals back to the photovoltaic inverter through the monitoring terminal when the health state of the inverter is worsen. By means of the photovoltaic inverter health status monitoring and alarm system, overhauling and management of the photovoltaic inverter are facilitated, the reliability of a photovoltaic power generation system is improved, and unexpected power outage, explosion, fire hazards and other accidents are effectively avoided.

Description

technical field [0001] The invention relates to a photovoltaic inverter monitoring technology, in particular to a photovoltaic inverter health state monitoring and alarm system including various inverter working state data. Background technique [0002] With the increasingly tight supply and demand of human energy, the application technology of renewable energy continues to develop, and the application of new energy is becoming more and more popular.
