Smart Logger Local Commissioning Guide

Smart Logger Local Commissioning Guide - Common Difficulties Resolved

Introduction:

                The basic function of SmartLogger is to monitor and manage the PV power systems. It assembles all the ports, changes protocol, gathers and supplies data, and centrally monitors and maintains the devices in PV power systems.

 The network application of the SmartLogger that applies to the PV power systems are as follow:

1. Local operations on the SmartLogger using the mobile phone app through the built-in WLAN

2. RS485 networking, which enables the SmartLogger to connect to:

  Huawei devices such as solar inverters (80 in 3000A and up to 150 in 3000B) and PID modules

2.1                Third-party solar inverters, environment monitoring instruments (EMIs), transformer stations, and power meter     that use the Modbus-RTU protocol

2.2            Power meters that use the DL/T645 protocol

2.3           Devices that use the IEC103 protocol

3. MBUS networking, which enables the SmartLogger to connect to Huawei solar inverters and PID-PVBOXs that support MBUS communication

4. Connection to management systems:

4.1                  Connects to a management system that uses the Modbus TCP protocol over a wired or wireless network.

4.2                   Connects to a management system that uses the IEC104 protocol in the LAN over a wired network.

Installation and Appearance:

The image below shows the details of peripherals in smart Logger 3000A

The installation of the smart logger should be done as recommended in the picture below:

Mandatory Connections and Checks:

After installation, make sure the following inputs of the 3000A are connected orderly to ensure the smooth communication between the inverters and the device.

1.       Connecting the PE Cable

Make sure the chassis is earthed properly.

2.       Antenna and the Power Cable:

When the logger connects to the power supply through the 12 V input port, the 24 V input port can function as the 12 V power output port to supply power to a device. The 24 V DC power supply is used.

3.       Ethernet Cable Connection

The LAN port is used for connection/communication between your laptop or PC and Logger while commissioning it via WEB UI

The WAN port is used for connection/communication between your internet router and Logger

 4.       RS485 Connection

The inverter connects to one another in a daisy chain method using RS485 wire and then connects to the logger via one inverter input ports likewise. The other end of the RS485 connects to the communication ports available as com1/com2/com3 in the logger. For proper communication signals between the logger and inverter, make sure the wire is fixed rightly in the connectors, any losing can cause weak signals, hence affecting the communication.

The SmartLogger can connect to RS485 communications devices, such as a solar inverter, an environmental monitoring instrument (EMI), a PID module and a power meter over the COM port. Ensure that RS485+ is connected to COM+ of the SmartLogger and RS485– is connected to the COM– of the SmartLogger.

 5.       Sim Input (In case of Wireless/4G networking)

In case of no internet available via ethernet, 4G sim can be used for communication between the logger and NMS.

6.    MBus Connection:

If both the SmartLogger and the solar inverter support MBUS, the SmartLogger can be connected to the solar inverter through an AC power cable. In this case, you do not need to connect the RS485 communications cable to the solar inverter. If the SmartLogger uses an AC power cable as the communications cable, an MCB and a knife fuse switch need to be installed to prevent device damage in the case of short circuits.

The port adjacent to ethernet cable port on the left is MBUS port.

Networking Scenarios:

 The SmartLogger supports the following wired networks:

1.       Fiber ring network

2.       Fiber/Ethernet star network:

1.       4G Network:

Indicators:

There are 3 indicators on the bottom left side of the logger named as:

1.       RUN

2.       ALM = Alarm

3.       4G

Powering Up The Smartlogger :

      Connect the power supply. There are two ways to connect the power supply:

      Method 1:

                When a power adapter is used, connect the power adapter cable and turn on the switch on the AC socket side. The rated input voltage of the power adapter is 100–240 V AC, and the rated input frequency is 50/60 Hz. Select an AC socket that matches the power adapter.

      Method 2:

                  When a DC power supply is used, check that the cable between the DC power supply and the SmartLogger as well as the Smart Module is connected properly, and turn on the upstream power switch of the DC power supply. When MBUS is used for communication, turn on all the upstream switches of the MBUS port.

      Commissioning The SmartLogger:

         There are two ways to commission the smart logger:

1.    Via Fusion Solar App

2.    Via WEB UI

1.       Via FusionSolar App

1.       For commissioning via FuisonSolar app, access the smart logger through WLAN function that is enabled by default, otherwise hold down the reset button for 1-3 secs for enabling the WLAN function.

2.       Set the date and time and Power meter (if required) for the logger.

3.       Add communication devices connected to the smart logger, Tap Auto Device Search to add the inverters, in case not all devices are added, set the Auto Assign Adress to enable so that the devices having duplicate IP addresses could be assigned a different IP automatically.

4.       Set the gride code and use Batch Set option to set the same settings for all the connected inverters.     

5.       Set the network parameters for logger, either wired or wireless.

             If wired network the ensure the following:

-          Set ethernet parameters, Enable DHCP for automatic allocation of ethernet parameters.

-          If DHCP is disabled, we can manually set the ethernet parameters. We have to ensure that the router and logger are on the same network segment and the logger has the different IP address than other devices on the LAN router.

-          Set default gateway and Primary DNS server to the IP address of the LAN router

-          If Primary DNS server cannot resolve the problem, use Secondary DNS server.

6.       Set the parameters for connecting the logger to the NMS.

-          Server – Intl.fusionsolar.huawei.com             

-          Port Number – 27250

-          Address Mode – Logical Address

-          SLL Encryption – Enabled

-          Secondary Challenge authentication – Enabled

2.       Via Web UI:

          When the logger is connected to a wired network for the communication with NMS, the commissioning      can be done via Web UI too. Following are the easy steps to get your logger onboard via Web UI

0.       Set the IP address on the PC on the same network segment as the smart logger using following steps

-          Go to Control Panel -> Network and Internet -> Network Connections -> Local Area Network

-         Go to the properties on Local Area Network by right click and a window of Networking will open

-          First uncheck the highlighted option *Internet protocol Version 4 (TCP/IPv4) * and the check it again to get the *properties* option accessible on the current window.

-          After entering the properties of *Internet Protocol Version 4 (TCP/IPv4), select the option “Use the following IP address” and enter the IP address as guided:

The IP address configuration are as follow according to the connection with LAN and WAN:

Note: If the IP address of the WAN port is on the 192.168.8.1—192.168.8.255 network segment, the IP address of the LAN port automatically switches to 192.168.3.10 and the default gateway is 192.168.3.1

-          After this step, enter the IP address of the logger i.e., 192.168.8.10 when connected via LAN port to the PC, in the address bar of a browser. If you log in to the WebUI for the first time, a security risk warning will be displayed, click Continue to this website.

-          Log in to the WebUI with Username: admin

                                              Password: Changeme (one time password) after this you change your password immediately for 2^nd login.

-          On the Deployment Wizard page, set parameters as prompted and demonstrated in the photos below:

1.       We need to set the parameters of Management System from settings and set them as shown in the figure below;

2.       After setting the management system parameters, we need to set the Communication Parameters

A.      Wireless Network

B.      Wired Network

Notice:

·         The web software version corresponding to the WebUI screenshots in this document is SmartLogger specific model/version. The screenshots are for reference only.

·         The parameter names, value ranges, and default values are subject to change. The actual display may vary.

·         Delivering a reset, shutdown, or upgrade command to the solar inverters may cause power grid connection failure, which affects the energy yield.

·         Only professionals are allowed to set the grid parameters, protection parameters, feature parameters, and power adjustment parameters of the solar inverters. If the grid parameters, protection parameters and feature parameters are incorrectly set, the solar inverters may not connect to the power grid. If the power adjustment parameters are incorrectly set, the solar inverters may not connect to the power grid as required. In these cases, the energy yield will be affected.

·         Only professionals are allowed to set the power grid scheduling parameters of the SmartLogger. Incorrect settings may cause the PV plant to fail to connect to the power grid as required, which affects the energy yield.
