This device can do round-the-clock measurement of wind speed and direction, precipitation, air temperature and humidity, irradiation, atmospheric pressure, and other local meteorological parameters. Via matched data collection communication line, it can connect with and transfer the gathered data to PC for data analysis and processing. Data recorder has functions of data acquisition, data memory, parameter setting, friendly software interface and standard communication.

The main function of AC power distribution cabinet is to supply grid-connected interface through power distribution. This cabinet is mainly composed of breaker, SPD, electricity meter, grid-connected interface and AC current and voltage meters, etc.

DC distribution cabinet is used to combining by connecting DC cable output by combiner box, output to grid-connected inverter. It includes DC input breaker, PV SPD, and optional anti-current flowing backwards, easy to operate and maintain.

For large-scale PV grid-connected power generation system, in order to reduce connection cable between inverter and PV components, easy for maintenance and improve reliability, normally add DC combiner box between inverter and PV components. Aotai PV array lightening protection combiner box is designed for this purpose, it can work with Aotai inverter to combine complete PV power generation system. With PV combiner box, user can connect some PV components with same standard into 1 PV module string in parallel according to inverter input DC voltage range, and connect some PV module string to PV array lightening protection combiner box, passing through lighting protections and circuit breaker, then output, this makes convenient for later inverter to connect in.
