Setting Up Pylontech US5000 Batteries with a Victron System
This guide outlines the correct wiring, startup, and shutdown procedures for integrating Pylontech US5000 lithium batteries with a Victron inverter system via CAN-bus communication. It is compatible with Victron and Deye hybrid inverters.
🧷
Wiring Overview
🔌 Inverter Communication:
-
Connect the inverter to the ACAN port on the master battery using a standard CAT5e/CAT6 Ethernet cable.
🔗 Battery Interconnection:
Master Battery:
-
No DIP switch configuration required.
-
LinkPort 0: Leave empty.
-
LinkPort 1: Connect to LinkPort 0 of the next battery.
-
Repeat the connection chain for all batteries.
-
On the last battery, leave LinkPort 1 empty.
Ensure that all DC power cables (positive and negative) and ground connections are securely installed in parallel across all battery units, following the wiring reference provided in the diagram below.
⚙️
Startup Procedure
Turn ON the power switch on each battery unit.
-
No lights will appear yet — this is expected.
-
Press and hold the red SW (Power) button for 1–2 seconds on each battery.
-
LED indicators will light up.
-
The batteries will auto-address sequentially.
-
For US5000B models:
-
Turn ON the breaker switch on each battery.
-
This allows current flow after the stack is energized.
-
🔧
CAN-Bus Configuration in Victron
After the hardware setup:
-
Go to Settings > Services > BMS-CAN port on the Victron GX device (e.g., Cerbo GX).
Set the CAN-bus profile to:
➤ 500 kbit/s
This ensures stable communication between the Victron system and Pylontech batteries.
🔋
How to Check if Battery is Working in Victron (for Deye, go to this link: Battery Check)
1. From the Cerbo GX screen, click Menu.
2. Select Pylontech battery.
3. Go to Details.
4. Under Battery modules, confirm it shows 12 online, 0 offline (or matching the number of connected batteries). This indicates all battery modules are functioning and properly detected.
⏹️
Shutdown Procedure
To safely shut down the Pylontech battery system:
Turn OFF the inverter (Victron or Deye).
Switch OFF the breaker (if using US5000B) on each battery.
Press and hold the red SW (Power) button on each battery for 1–2 seconds until all LEDs turn off.
Turn OFF the battery’s power switch (on the side or rear, depending on the model).
⚠️ Always perform shutdown in this order to avoid communication or protection faults.
