🔌 1. How do I configure BMS communication with lithium batteries?
EASUN SMG II 11KW supports RS485 communication with a variety of BMS systems such as Pylontech, JK, Jikong, and Daly.
Pylontech BMS: Select battery type “Li2” in the inverter menu and set BMS to “Pylon RS485”.
Daly BMS: Some users report success using “Li4” and setting Daly BMS to "Growatt" protocol.
JK BMS: It is recommended to use “Li2” and ensure correct wiring.
Note: Wiring methods may vary depending on the BMS brand. Please refer to the connection diagrams or consult technical support.

⚡ 2. What is the idle power consumption of the inverter?
According to user feedback, the no-load power consumption is around 90W, and with a light load (200-300W), it may reach 100–120W.
The official specification lists idle consumption as 50–60W, but actual performance may be slightly higher. It's recommended to account for this in system design.

☀️ 3. What is the minimum PV voltage required to start the inverter?
The MPPT controller requires at least 120VDC PV input to start, but a recommended input of 250VDC or higher is suggested to ensure stable power output under load.

🛠️ 4. How can I fix the issue of the LCD screen flickering?
Some users have reported flickering on the inverter's display.
A common solution is to connect an X2-class capacitor in parallel between PV+ and PV- to stabilize voltage fluctuations.
⚠️ This operation requires electrical knowledge. Please consult a professional.

🔄 5. Does the inverter support parallel operation?
No, the EASUN SMG II 11KW does not support parallel connection.
If you need parallel functionality, consider models in the EASUN SMW series that support this feature.

📶 6. How does the WiFi monitoring work?
The inverter has a built-in WiFi module and can be monitored via a mobile app.
Download the recommended monitoring app and follow the instructions in the user manual.
Note: Data updates from the WiFi module may occur at 5-minute intervals.

🔋 7. Can the inverter run without a battery?
Yes, EASUN SMG II 11KW supports batteryless operation.
In this mode, the inverter uses PV input directly to power loads. However, it is recommended to carefully evaluate power stability and load demands when designing your system.
