2.1 Device Overview

The EnerLog device features several interfaces for monitoring and communication. These include:

• G (RS485): Four RS485 channels are available. Channels 1-3 can monitor equipment, while channel 4 is for debugging.
• H (Power interface 1): A 12V power adapter interface for providing working power.
• I (Power interface 2): A backup power input port.
• J (Card slot): A flow card socket (functionality not yet implemented).
• K (Reset): A reset button. A short press (over 1 second) restarts the EnerLog. A long press (over 10 seconds) restores factory settings.
• L (RJ45): An Ethernet cable interface.
• M (USB): A USB interface for local upgrades.
• N (ANT): An antenna interface (not currently available).

2.2 Unpacking

2.2.1 Packing List

The EnerLog and its accessories include:

2.2.2 Serial No. and Check Code

The EnerLog's serial number (SN) and check code (CC) are unique alphanumeric codes found on the outer package and case, used for identifying individual units. These are required when uploading data to the web server.

2.3 Function Introduction

The EnerLog supports network communication via wired WLAN, allowing it to connect to a cloud server. It uploads monitored data to the ATESS server for remote access and monitoring. It also supports RS485 communication for industrial applications, enabling monitoring, setting slave devices, and performing online upgrades. Accessing the EnerLog's internal IP address allows for parameter settings, device addition, and viewing, as detailed in section 4.4. The EnerLog monitors devices through RS485.

3 Installation and Connection

3.1 Installation environment

Environment Requirements:

• Installation: Indoor use only.
• Temperature: -25°C to 55°C.
• Conditions: Avoid humidity and direct sunlight.
• RS485 Distance: Maximum communication distance for wired RS485 is 500m. Take precautions against interference.
• Network Cable: Maximum length between the router should not exceed 1000m.

3.2 installation method

3.2.1 Installation Steps:

1. Install the EnerLog on a vertical or horizontal surface.
2. Connect the RS485 interface on the EnerLog to the RS485 interface on the device (refer to section 3.3.1 for details).
3. Communication Method: For the standard version, connect the network cable.
4. Power Connection: Choose one of the following methods:
   • Use the provided 12V DC power adapter and conversion plugs (available for China, Britain, USA, Europe, and Australia).
   • Connect to the 12V-24V DC power input port, ensuring correct polarity.

3.3 Connect with device

The EnerLog can communicate with energy storage inverters, BMS, and other equipment for data collection.

3.3.1 RS485 cable connection

EnerLog (master) communicates with devices (slaves) via RS485 wired connection. The 485-A port on the device connects to A1, A2, or A3 on the EnerLog's RS485 port, and the 485-B port connects to B1, B2, or B3 respectively. The A1B1, A2B2, and A3B3 channels are functionally identical.

Diagram Description: A schematic shows the RS485 connection with terminals labeled A1, B1, A2, B2, A3, B3 on one side and RS485-A, RS485-B on the other.

The EnerLog can monitor up to 60 devices when connected in parallel via RS485 wired communication (20 devices per RS485 channel). Other RS485 communication equipment like BMS and combiner boxes use the same connection method.

Notice:

• When connecting multiple inverters, one inverter per RS485 channel must have a 120Ω matching resistor to ensure stable communication. It is recommended to connect this resistor to the farthest inverter. Channel 3 is dedicated for electricity meters and does not use matching resistors.
• Equipment from manufacturers other than ATESS may not be supported for monitoring.

4 EnerLog Internal Page parameter setting

Precautions for configuration:

• If the interface does not refresh after saving, power cycle the device and restart. Check the "device status" after restarting.
• Only configure parameters as instructed; do not modify other parameters.

4.1 IP access method

It is recommended to use EnerLog with a router. For the initial login to the internal page, search for the IP address via the router's backend.

4.1.1 Dynamic IP login

1. Connect the PC and EnerLog to the same router (same LAN).
2. Find the EnerLog's IP address in the router's management page (e.g., H3C router's DHCP Server List, by matching the EnerLog's serial number). Ensure the router's DHCP function is enabled.
3. Enter the found IP address in a web browser to access the internal page.

4.1.2 Static IP login

For static IP access:

1. Connect the computer and EnerLog directly via a network cable.
2. On the computer, configure its IP address and EnerLog's IP address to be in the same network segment (e.g., if EnerLog is 192.168.0.2, set the computer to 192.168.0.5 with subnet mask 255.255.255.0 and gateway 192.168.0.1). DNS server settings are not required.
3. Enter the EnerLog's IP address in the computer browser to access the internal page.

4.2 Login to the internal page

Ensure communication cables are securely connected. Enter the EnerLog's IP address in the browser. The computer and EnerLog must be in the same network segment.

The default login credentials are username: admin, password: admin.

If a router cannot be used, a fixed IP connection is possible. The EnerLog can be accessed via its built-in page for the first 2 minutes after startup. If this period is exceeded, DHCP will automatically enable. Alternatively, connect directly via network cable, set the computer's IP address (e.g., 192.168.0.254 for EnerLog, set computer to 192.168.0.5), and access the internal page.

The fixed IP can be modified in section 4.6.1. If forgotten, reset the EnerLog (Chapter 6.1), which will clear all data.

4.3 Datalogger status view

Accessing "EnerLog datalogger status" displays "system status information", "serial number", "server address", and "number of connected devices".

4.4 Add or delete device

Before monitoring, add devices via the "Add Device" page.

4.4.1 Add device

1. Select the device type from the first drop-down list (e.g., ATESS Inverter).
2. Select the RS485 channel (e.g., RS485-1).
3. Enter the communication address of the monitored device (must be unique).
4. Click "Add" and then "Save".
5. Verify the addition on the "Device Status" page.

Equipment Type Descriptions: ATESS Inverter (HPS, PCS, PBD), BCU Battery (BMS motherboard), MBMS Battery (BMS three-layer board).

4.4.2 Delete device

1. Select the device type, RS485 channel, and communication address.
2. Select "Del" and click "Save" to delete the device.
3. Verify deletion on the "Device Status" page.

Notice: Ensure parameters match when deleting. An address occupied by a new device requires the old device to be deleted first.

4.5 Setting the baud rate

The default RS485 baud rate is 9600. To modify:

1. Navigate to "system management" and select baud rate.
2. Choose the RS485 channel to modify.
3. Save the changes.

4.6 Network communication

EnerLog connects via network cable. Options include automatic IP allocation via DHCP or a fixed IP.

4.6.1 Networking settings

• Set "DHCP ENABLE" to 1 for automatic IP assignment (default) or 0 for static IP.
• For static IP, disable DHCP, then set IP, gateway, subnet mask, and DNS.
