Abstract

The invention provides a solar photovoltaic power supply monitoring system. The solar photovoltaic power supply monitoring system comprises a monitoring host, a programmable controller, a sensor assembly and a monitoring power supply module; the monitoring host is provided with a touch screen; the programmable controller is connected with an expansion module through a parallel bus; the sensor assembly comprises a photovoltaic voltage sensor, a battery pack voltage sensor, a load voltage sensor, a temperature sensor and a current sensor; the sensor assembly transmits a detected signal to the programmable controller or the extension module thereof; and the monitoring host receives all signals through the programmable controller, processes the signals and displays the signals on the touch screen. Parameters such as voltage, current and temperature in the solar photovoltaic power generation system are monitored through the monitoring host and the programmable controller; and the power supply of the generator can be automatically and selectively turned on according to the power generation capacity of the photovoltaic cell panel, so that the normal operation of the battery pack is ensured, and the normal operation of the solar photovoltaic power generation system is ensured.

Description

technical field [0001] The present application relates to the technical field of solar power generation monitoring technology, in particular to a solar photovoltaic power monitoring system. Background technique [0002] Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight energy into electrical energy. Regardless of whether it is used independently or connected to the grid for power generation, the photovoltaic power generation system is mainly composed of three parts: solar panels (components), controllers and inverters. They are mainly composed of electronic components and do not involve mechanical parts. Therefore, photovoltaic power generation equipment Extremely refined, reliable, stable, long life, easy to install and maintain. [0003] Especially for remote areas where there is no mains power supply (such as natural gas pipeline monitoring stations in remote areas), it is the preferred power su...
