Product Description
Product Description
AGF-T Perforation type PV confluence acquisition device
1 General
AGF-T Perforation type PV confluence acquisition device is specially designed for smart PV combiner box. It is used for monitoring the running state of solar panels in solar cell arrays, measuring the currents of solar cell, detecting the state of surge protection devices and DC breaker. The device is equipped with RS485(Modbus) communication port for transmitting all the datas to master device.
2 Product Naming
*Power supply filter module is only optional when there is filtering requirements to power supply
3 Characteristics
Primary current is connected in through perforation. Easy installation, high safety
With Hall sensor, the max isolation measuring current 20A
Voltage measurement range for Bus bar is up to DC1kV
LED display, fit for checking and testing operation in wide-temperature or outside environment.
With the function of inner temperature measurement for real-time measurement of the inner temperature of combiner box
With RS485 Modbus RTU
More options of power supply
Compatible with din rail installation and baseboard fixation installation, small dimension saving more box space.
DC Bus bar voltage input circuit with built-in DC 1kV fuse
4 Product function
Photovoltaic cell open circuit alarm to cooperate with group string voltage and judge Comprehensively
With 3-channel switching state monitoring to collect output idle contact information of DC breaker ,lightning protector. protector etc
Option RS485 port, Modbus-RTU protocol; programmable slave address, baud rate, data format
English LCD display,convenient to set parameters and check the data
5 Technical Parameters
6 Outline and installation
6.1 Outline dimension
6.1.1 Power supply module and power supply filtering module size(Figure 1)
Note: Imaginary line is the fixing size of the bottom plate
As power supply module is heavy, bottom plate is needed in installation to avoid its coming off during transportation.
6.1.2 The extension module mounting dimensions (Figure 2)
Note: Imaginary line is the fixing size for base plate.
6.1.3 Confluence acquisition module installation dimension
8-channel confluence acquisition module installation dimension(Figure 3)
4-channel confluence acquisition module installation dimension(Figure 4)
Configuration of 8-channel or 4-channel confluence acquisition module will be decided by actual needs: when 4 channels or less are needed, 4-channel confluence acquisition module will be installed, when needed channel number is 5 to 8, 8-channel confluence acquisition module will be installed. When needed channel number is more than 8, then the number will be divided by 8. If there is a remainder in the result and the remainder is less than 4, then 4-channel confluence acquisition module will be installed. If the remainder is more than 4, 8-channel confluence acquisition module will be installed.
6.1.4 LCD display module installation dimension (Figure 5)
6.2 Connections of modules
6.2.1 Data cable connection way
The connection between each module is through the external data line. Please confirm the sequence of the two external data line ports before connecting each module. Each confluence acquisition module has two outside connection ports(Figure 4): Port I and Port II, in which Port I is used to connect upstream module and Port II is used to connect follow-up modules. Please pay attention to it that the propulsion part of the data line connector must be fixed with the groove on the port.
The connection sequence order of PV confluence acquisition modules must follow: confluence acquisition module 1's port Ⅱ-->confluence acquisition module 2's port , Ⅰ confluence acquisition module 2's port Ⅱ-->confluence acquisition module 3's port .When connecting the confluence acquisition modules ,multiple confluence modules should be in sequence order, it is not allowed to insert any other function module between two sequenced confluence modules. Wrong connection will lead to abnormal operation of the device.
LCD display module can be connected with Port II of confluence acquisition module, The LCD display module is not necessary to be connected in at ordinary time except when testing and checking.
The address allocation of PV confluence acquisition module is automatically distributed by the power module(main module), The first confluence acquisition module connected to the power module will be distributed automatically with 1st to 8th channels, and the next confluence acquisition module connected to port II will be distributed automatically with 9th to 16th channels, the final confluence acquisition module is distributed automatically with 17th to 24th channel.
6.2.2 Installation schematic
Note: The arrow shows current direction. Wrong connection will lead to abnormal operation of the device.
6.3 Definition of input port
After the address of confluence acquisition module is distributed by the main module,the input channel address of first module is from 1st to 8th channel,the input channel address of second confluence acquisition module is from 9th to 16th channel,the input channel address of final confluence acquisition module is from 17th to 24th channel. The input channel definition of 1st to 8th channel of a single module is shown as Figure 3.
7 Wiring mode
Note: Power supply circuit and voltage measuring circuit must be installed with fuse with 3A rated current and rated voltage that is the highest working voltage in these circuits to ensure safety.

FAQ
Analysis of common faults and causes
The measurement of the device is not accurate
Check whether the positive and negative terminals of the voltage are correct
Is the current passing through the hall sensor in the right direction
Check whether the IE setting of the device is consistent with the hall sensor used
Whether the output signal of hall sensor matches the required input signal of the device;
Check whether the output negative pole of the voltage output hall sensor is connected to the device GND
Abnormal communication
Check whether the communication cable is connected normally
Check whether the A and B terminals of communication are staggered
Check whether the device address is set correctly and the communication baud rate is set correctly
Multi - device communication is not normal, first try the single communication, to see if it is normal.
The device does not display properly
Check whether it is caused by the insufficient carrying capacity of the built-in power supply to the hall sensor. Replace the external switching power supply to power hall
