LAN EzLogger Pro Data Upload and Function Configuration

How to Use LAN EzLogger Pro
After EzLogger Pro is connected to the collected data, one should connect EzLogger Pro to the Internet, so that EzLogger Pro can upload the collected data to the server. Dynamic IP (DHCP) is a default function for EzLogger Pro.

• If the network device is in dynamic IP mode(DHCP), switch the EzLogger Pro to static IP mode and connect the EzLogger Pro to the PC to configure the parameters using the ProMate software. After the configuration, switch the EzLogger Pro to dynamic IP mode. Then connect the NET port of EzLogger Pro directly to the LAN port of the router, and enable the dynamic IP (DHCP) function of the router. EzLogger Pro can connect to the network and automatically upload the collected data to the monitoring platform.
• If the network device is in static IP mode, switch the EzLogger Pro to static IP mode and connect the EzLogger Pro to the PC to configure the parameters using the ProMate software. Modify network information such as the IP address of the EzLogger Pro to enable the communication between the EzLogger and network device. Then connect the NET port of EzLogger Pro directly to a network device, such as the LAN port of the switch. EzLogger Pro can connect to the network and automatically upload the collected data to the monitoring platform.

EzLogger Pro Configuration

Connecting ProMate to EzLogger Pro
ProMate software is launched by us for functional configuration of EzLogger Pro, by which we can realize modification to the IP address of EzLogger Pro, quantity setting of connected inverters for port, time setting, sound and light alarm, RCR, DRED enabling configuration, field debugging, etc. Firstly, the user needs to install “ProMate” software in the computer. Please access to GoodWe official website and search for“ProMate” to download the program and complete the installation.

Configuration Method for EzLogger Pro Static IP Address:
If the user has a static IP, it is necessary to switch EzLogger Pro to the static IP mode. That is, press the Reload key for about 10 seconds to reset and restart EzLogger Pro, The LEDs on EzLogger Pro will blink one after another from right to left. After restart, EzLogger Pro will be switched to static IP mode(default IP:192.168.1.200),then modify the computer’s IP address, take WIN7 as an example, the steps are as below. The user can find the methods from the Internet for modifying IP addresses of different computer systems.

1. Switch EzLogger Pro to static IP, then use cables to connect EzLogger Pro “NET” port to the Ethernet port of the computer.
2. Turn on the computer, right click on “Network ” on the desktop, and click on “Properties”.
3. Click on “Change adapter settings”.
4. Pop up the local connection dialog box, right-click on “Local Connection” and then click on “Properties”. Pop up a dialog box as below:
5. Double click on “Internet Protocol 4 (TCP/IPv4)” to pop up the “Properties” dialog box of “Internet Protocol 4 (TCP/IPv4)”, then complete the setting for the dialog box in accordance with the following requirements.

The defaulted IP address for EzLogger Pro is 192.168.1.200. In order to put your computer and EzLogger Pro under the same network segment, you should set the IP address and the default gateway in 192.168.1. XXX network segment (1 ≤ XXX ≤ 250 and XXX ≠200).

For example:
The user can set the IP address as 192.168.1.100 and the default gateway as 192.168.1.254.

Click “Connect” button in ProMate to connect ProMate to EzLogger Pro, and the system will indicate “The connection is successful”, as shown in Figure 5.2-6.

Quantity Configuration for Inverter Communication Port
Terminal configuration is used for setting EzLogger Pro ‘s COM1,COM2,COM3 ports which the quantity of inverters connecting,assume port 1(corresponding communication port COM1) connecting the quantity of inverters is 2,then check port 1,the quantity settings is 2,click on “Set” button to finish the configuration. As picture 5.2-7.

Please set the quantity of devices of each port according to the quantity of inverters actually connected. Upon the completion of setting, the user can check the actual communication status of inverter from the LED indicator of EzLogger Pro (see Section 2.3 LED Indicator).

Time Setting
Time setting will synchronize the time of EzLogger Pro and inverter and the time of synchronization server. Click on “Set Time” to pop up the following dialog box, as shown in the figure below. Then click on “OK” after setting the time, as shown in Figure 5.2–8.

DRED setting
DRED function can control the inverter’s generated power according to power grid control signal,only apply to Australia and New Zealand.Before start using DRED function,it will have to connect electricity meter well first and set inverter’s safety country,then set installation capacity and CT current ratio .etc parameters.

Below instructions are installation capacity and CT current ratio:

1. Installation capacity:The inverter’s sum of rated generate electricity,such as there are 2 pieces of 10KW inverters on site,then the installation capacity is to set 20KW, calculate method is 2*10KW.
2. CT current ratio:Current transformer labeled input and output current ratio.For example,labeled ratio was 200/5,then CT current ratio setting is 40. Click “Start Using DRED” button after setting finished to achieve the configuration.As picture 5.2-13 showed.

• Meter power means: The electricity meter measure the grid power, display positive value means the user sell electricity power value, display negative value means the user buy electricity power value. Inverters power means: All of the inverters’ sum of generate electricity power value.
• Load power means: Load consumption power.
• When start using DRED function , if EzLogger Pro detects inverter had earth fault,then it will trigger sound-light alarm function:buzzer will ring for 1 minute,and RUN LED will be lighting for 1 minute. After 1 minute,the alarm will stop and keep on detecting every 30 minutes until fault disappearing.

RCR setting
RCR function only apply to Germany.If the customer needs to start using RCR function,please set inverter’s safety country first,then check “Enable” to enable RCR function.As picture 5.2-15.

Field Debugging
ProMate can also be applied to field installation and debugging. After installation is completed, click on “Refresh” to show whether the inverter is online or not. If the system prompts “off line”, please check whether the connection cable has any problem, and then timely solve the problems till the system shows that all the inverter are “on line”. It should be noted that it takes time to get the inverter status due to communication rate problems, as shown in Figure 5.2-12.

(Optional) Modification to the IP address of EzLogger Pro
The user can adopt the required configuration after connecting ProMate software to EzLogger Pro  In static IP mode, the user can configure IP address, subnet mask, gateway and DNS that can be accessed to Internet as required, as shown in Figure 5.2-8

For example:

• The Users’ IP Address 192.168.8.115 The Users’ Gateway 192.168.8.1
• The Users’ Subnet Mask 255.255.255.0 The Users’ DNS 8.8.8.8
• Put the above data into LAN configuration, and then click the “Set” button to complete the set.
• Now IP address of EzLogger Pro has been modified as the configuration as required by the user, and physical connection between EzLogger Pro and ProMate can be disconnected after the configuration is completed. Then the Internet will be available just by plugging Ethernet cable into EzLogger Pro.

Program Upgrade: Upgrade EzLogger Pro

1. Local Upgrade: Put the bin files required by upgrade in the root directory of U disk (please use the U disk with 2.0 port, FAT32 format ), insert the USB flash disk in to the USB port of EzLogger Pro, cut off the electricity to EzLogger Pro and then repower it, so as to enable automatic update of the program. The bin files for program upgrade is named as “EzLoggerPro_new.bin”. Bin files will be sent to client via E-mail. And the client shall save the received bin files in root directory of U disk, and check whether the file name is “EzLoggerPro_new. bin” or not. If not, please change into this name, otherwise inconsistent file names  will cause the failure of the program upgrade. The shining of all of the eight indicatorlights of EzLogger Pro in the program upgrade process indicates that the program is upgrading; the indicator lights will restore to the normal state when the program upgrade is completed. It is forbidden to cut off electricity in the program upgrade process.
2. Remote Upgrade: Upgrade program is uploaded to the server by GOODWE in the background, so as to enable automatic check and update of EzLogger Pro.
