Why can't photovoltaic power plants be short of data logger?
The data logger is a device that collects the data of photovoltaic grid-connected inverters, convergence boxes, weather stations, electricity meters and other equipment in photovoltaic power stations through the communication protocols such as RS485, RS232 and RS422, and transmits the data to the database through GPRS, Ethernet, WIFI, 3G and other methods. The data logger can be divided into built-in logger/external logger: Built – in logger: embedded in inverter, used to collect inverter data, also known as embedded data acquisition module. ( see SolarMAN- built-in module for details ). Why use data logger? Although monitoring equipment is not installed in every power station in China at present, with the continuous maturity and popularization of solar photovoltaic power generation technology, digital acquisition and remote monitoring are becoming more and more important. For large-scale ground power stations, few people or even no one on duty is the fundamental way to reduce opera...
