Photovoltaic Interface Adapter

1 Product Overview

DAQ-GP-485PIA Photovoltaic Interface Adapter (hereinafter referred to as the adapter) is designed by our company in response to the latest requirements of State Grid Corporation in the field of photovoltaic power generation. The photovoltaic interface adapter is a device that cooperates with the photovoltaic protocol converter to realize the collection of inverter power generation and electricity consumption information. It supports photovoltaic inverter manufacturers such as Ginlong, GoodWe, Growatt, Huawei, Aotec, Sungrow, Chint, Sanjing, Shouhang, Megarevo, Solis, and Hopewind. It is used for the switching of dual master station login between the electricity information collection system of a single inverter and the manufacturer's cloud platform. It expands the original 1-channel communication RS485 port of the inverter into two channels. Under the condition that one channel ensures the communication of the manufacturer's cloud platform is not affected, the other RS485 port is connected to the photovoltaic protocol converter, so that both master stations can normally collect and issue control commands, etc. The switching structure adopts ARM microcontroller MCU control to realize channel selection. The default is to select the manufacturer's RS485 communication channel. When the protocol converter communicates, it sends a switching command to switch to the grid RS485 channel, and switches back to the manufacturer's communication channel after the communication is completed. The adapter should adopt a unified main structure, and realize communication and control of inverters with different interfaces by replacing the aviation plug cable that matches the inverter interface. 2 Service Philosophy Our company solemnly promises: What you buy is not just a product, but also meticulous and thoughtful technical support services!!!( =^_^= ) For this product, only ordinary workers are needed for on-site power connection and installation!

The default baud rate of the RS485 interface is 9600bps, with parity mode being none, data bits 8, stop bit 1. It can adapt to the 485 interface rate of the inverter to realize automatic serial port matching. 5 On-Site Installation 5.1 Installation Form On-site installation diagram The converter adopts rail-type installation, which is convenient and reliable. 5.2 Port Definition Port 1: Install the original inverter 4G module (collection stick) here. Port 2: The aviation plug is installed to the original installation position of the corresponding photovoltaic inverter 4G module (collection stick) (the adapter is equipped with a 1.5-meter cable). Port 3: Connect to the RS485 interface of the corresponding photovoltaic protocol converter (the adapter is equipped with a 1.5-meter cable). 5.3 Installation and Wiring Precautions Common problems in RS485 wiring: The RS485 line of the adapter is reversed with the RS485 line of other devices; The RS485 line A and line B of the adapter are short-circuited; the aviation plug is not installed in place. 6 Name and Content of Hazardous Substances in the Product 7 Transportation and Storage The product should not be subjected to severe impact during transportation and unpacking.
