Sumitomo electric industrial co., LTD (headquarters: central in Osaka city, President: inoue, hereinafter called "the company") has developed for the use of the high power panel solar power station group PLC series * * squared creates monitoring device, and has already started to accept orders, will start shipment since early 2022.Each group PLC monitoring device can monitor the 20 most group chain, a group of bunch of maximum measuring 20 a current (amps).

In recent years, in order to reduce the cost of construction and operation of solar power station solar panel from the mainstream of 1000 v to 1500 v, continuously evolved to high voltage, current value of each set of string are also increasing.

In this background, the company for solar panel used in the detection of fault "group PLC series monitoring device", to enhance the support for dc voltage 1500 v, the function of the current 15 a model, developed the products can be measured for each group of 20 largest a current.This is Japan's first (according to the results of the survey to our company, can measure the maximum 20 a current group PLC technology monitoring device products.

Moreover, even if the measurement from 15 a group list current up to 20. A, the volume of the device, there is no change, this is a small product easy to install.

For the construction of solar power stations for the realization of carbon neutral, the company will continue to provide convenient group PLC series monitoring device, and the supplementary service, the stable operation of the power solar power station and efficient maintenance.

The main characteristic of this product

1.Support for dc 1500 v voltage of the power plant, a group of 20 series of electric current
2.Support for up to 20 group list of multiple design methods of * after junction box
3.Power line communications (PLC) technology group of string of data transmission ・ without laying communication lines, can greatly reduce the construction period and cost of solar power station ・ not use communication lines, thus will not generate an electrical potential difference in the is struck by lightning, have higher than RS485 communication lightning protection performance ・ has the antinoise performance of the company unique, compared with other forms of communication (RS485, wireless), can achieve more stable data communication
4.Will set series of monitoring device on cloud data analysis of AI, when an exception occurs, provide daily email and diagnostic services (optional)
5.To the Japanese domestic solar power station the delivery more than 10000 units

* 1 PLC (power line communication) : be used for power line communication line technology.This company product USES the low frequency of PLC technology, the use of below 450 KHZ frequency, string current measurement data set to overlay on the direct current (DC)
* string in the 2 groups: the smallest unit in an collection series solar panels
* 3: junction box used to connect multiple group summary list of wiring to power regulation system on the device
