Centralized Monitoring and Control Solutions

Centralized Monitoring and Control Solutions

Solar power plants involve many kinds of monitoring equipments, including all solar system related products, like combiner box, DC power distribution cabinet, Grid cabinet, AC power distribution cabinet, sun tracking unit, environment detector, etc. Monitoring system displays the real-time data and status information of each device, and can achieve real-time data storage, and remote control.

Inverter Wireless Monitoring Solutions

Inverter Wireless Monitoring Solutions

There are always quantity inverters dispersedly distributed in the solar power generation system. If adopts the traditional wired monitor method, there would be too much trouble with system cabling. Our solution uses ZigBee wireless network technology, which can access the inverters to ZigBee wireless data transmission equipment according to the different installation regional distribution through RS485 bus; Terminal node through multiple bridge route, and ultimately establish a wireless network connection with the center node. By monitoring the system can display a list of the inverters, daily generated energy, total generated energy, AC voltage, AC current, AC frequency, DC voltage, DC current, device temperature, fault information, power graph of that day, generated energy histograms of that month, other PV information and have abnormal alarm function.

ZigBee Wireless Date Transmission Equipment (iDM-PA Series)

ZigBee Wireless Date Transmission Equipment (iDM-PA Series)

The traditional method of monitoring equipment is through wired communication, but the disadvantage is complex wiring and limited transmission distance. The wireless monitoring solution, ZigBee network center receives commands via RS485 or RS232 data frame from the host machine, and then through the way of multicast pass command data frame of the individual ZigBee collector of ZigBee wireless network, finally passes the data to the terminal by RS485 and RS232 port terminal equipment. Each data frame ZigBee collector will transfer the data to the ZigBee network node which comes from its RS485 or RS232 port, through point to point mode, the central node returns the data to the host computer through the RS485 or RS232. ZigBee wireless communication technology is introduced into the application of the monitoring system to realize wireless data acquisition and to a certain extent solve the problem of wiring difficulty and poor adaptability of cable system.
