Installation and Configuration Manual
Pytes Lithium Battery V series
With Sinexcel/Isuna Inverter
BOM List
Before installation, you should prepare the following items:
| Item | Remarks | Quantity |
|---|---|---|
| Power Cable (DC) | Conductor cross-section: UL10269-1/0AWG-200mm-Amphonel 8.0mm or TMR-190*25*18mm. Cable diameters: 14 mm to 25 mm. Only copper cables may be used. The DC cables must be sized for the maximum battery voltage and the maximum battery current (refer to battery manufacturer documentation). | Depends on the number of batteries and the connection method |
| Com. Cable | CAN communication or RS485 communication | 1 |
| Battery | V5°/V5°a | Depends on the number of batteries and the connection method |
| Inverter | Sinexcel / Isuna | 1 |
Installation Steps
1. Power Cable Connection
Step 1
Connect the red and black power cables to the inverter DC connector as shown in the diagram. Diagram showing the DC input connector on the inverter, with red and black power cables being inserted.
Step 2
Parallel connect the other end of the power cables to the battery power terminals, positive to positive and negative to negative. Ensure the battery power switch is off. Diagram showing the battery terminals with positive and negative connections, and the corresponding power cables attached.
2. Communication Cable Connection
Connect one end of the communication cable to the inverter CAN/RS485-BMS port. Diagram of the inverter's rear panel, highlighting the CAN/RS485-BMS port where the communication cable is connected.
Connect the other end of the communication cable to the battery CAN port. Refer to page 4 for communication cable pin sequence.

5. Change the Battery Setting of the Inverter
CAUTION:
For more details about inverter battery settings, please check the inverter user manual.
Step 1: Download the App
Download the ESS LINK application from the Apple Store or Google Play.
Step 2: Run the App and Log In
Click the ESS LINK app icon to run the application. Register and log in. Screenshot of the ESS LINK mobile application's login screen, featuring fields for Account and Password, along with login options.
Click on the bottom right icon labeled "ME". Screenshot of the ESS LINK app's main dashboard, displaying energy data and system status, with the 'ME' icon highlighted in the bottom right corner.
Click on "Bluetooth Pairing" on the next page. Ensure WiFi and Bluetooth are enabled on your device before proceeding. Screenshot of the ESS LINK app's menu, showing various options including 'Bluetooth Pairing', which is highlighted.
Enter the Device number found on the WiFi Dongle. Then, enter your WiFi Name (SSID) and Password.
Click "Confirm" to wait for the auto-pairing process. A successfully connected window will be displayed. Two screenshots demonstrating the Bluetooth pairing process. The left shows the pairing screen where users input device number, WiFi name, and password, with 'Confirm' and 'Cancel' buttons. The right shows a confirmation pop-up indicating successful configuration.
Set Battery Parameters
Navigate to "My Device" > "Device Info" > "Parameters" to set the battery parameters. Screenshots illustrating the navigation path within the ESS LINK app: 'My Device' -> 'Device Info' -> 'Parameters'.
Enable Battery 1 by selecting "Lithium Battery" as the Battery Type and click "Confirm". Screenshots showing the battery parameter configuration screen in the ESS LINK app. The left displays battery enable options, and the right shows the selection of 'Lithium Battery' for Battery Type, followed by a 'Confirm' action.
Set the specific battery parameters as required. For example, set the Maximum Discharge Current to 75A, Battery Rated Voltage to 51.2V, Minimum SOC to 10%, Overvoltage Setting to 57V, and Undervoltage Setting to 45V. Screenshot of the ESS LINK app's parameter settings screen, detailing various battery parameters such as Maximum Discharge Current (75A), Rated Voltage (51.2V), Minimum SOC (10%), Overvoltage Setting (57V), and Undervoltage Setting (45V).
6. Check the Battery SOC
Return to the main menu. Navigate to "My Device" > "Device Info" > "Parameter" to check the battery's State of Charge (SOC) and other operational status. Screenshots showing the process to check battery SOC. The final screenshot displays detailed battery status, including Operating Status (Online), Basic Status (Sleep), Voltage, Current, Temperature, and SOC (72%).
7. System Monitoring
Download and run the Isuna APP for more information and system monitoring.
