How to Configure Deye hybrid inverter with PylonTech/Weco/BYD lithium ion battery

Описание: To configure a Deye hybrid inverter with a PylonTech, Weco, or BYD lithium-ion battery, you generally need to ensure that the inverter is compatible with the battery model and follow the correct setup process. Below is a general guideline that can help you configure your Deye hybrid inverter with these batteries. Make sure to follow the manufacturer's specific instructions for both the inverter and the battery model you are using.

1. Check Compatibility:
Ensure that your Deye hybrid inverter is compatible with the specific model of the lithium-ion battery you plan to use (PylonTech, Weco, or BYD).
Different inverters may have different communication protocols (e.g., CAN, RS485) and voltage ranges for batteries, so verify this from the datasheets or manuals.
2. Preparation:
Ensure proper safety measures: Before starting, make sure you are working in a safe environment and follow the manufacturer’s safety instructions (e.g., disconnect all power sources before installation).
Inspect the inverter and battery: Check that the inverter and battery are both in good condition and have not been previously damaged.
3. Battery Wiring to the Inverter:
DC Connections:
Connect the battery to the inverter's DC terminals. These are typically marked as “DC+” and “DC-”.
For a PylonTech battery, there will be a connection cable that may include a communication port (CAN or RS485), which must also be connected to the inverter.
For BYD and Weco batteries, follow the same process, but also ensure the communication wires are correctly connected.
Battery Communication:
CAN Bus: Many hybrid inverters, including Deye, use CAN bus communication for battery management. If your battery supports CAN, you need to connect the battery's CAN cable to the inverter's CAN port.
If the battery has a different communication protocol, such as RS485, ensure that you are using the correct terminals and wiring configuration for that particular protocol.
Wiring for Multiple Batteries:
If you're using multiple batteries in parallel, ensure that the wiring and balancing are done correctly. Some inverters require balancing resistors when connecting batteries in parallel.
4. Configure Inverter Settings:
After wiring, power up the system and access the inverter’s settings, either via the local display or through a remote monitoring tool.
Select the Battery Type:
In the inverter’s settings menu, you should be able to select the type of battery (PylonTech, BYD, Weco, etc.). This ensures that the inverter recognizes the specific battery's voltage and charging profile.
Set the Battery Parameters:
Configure the nominal battery voltage (e.g., 48V), capacity (Ah), and other parameters specific to your battery.
Some inverters have predefined profiles for popular battery brands. If you don’t see your battery listed, you may need to manually input settings based on the battery manufacturer’s specifications.
Set Charge/Discharge Limits:
Some hybrid inverters allow you to customize charge and discharge parameters to optimize battery lifespan or performance. You might need to adjust parameters such as maximum charge/discharge current, low and high voltage limits, and state of charge (SOC) range.
5. Check Battery Communication (if applicable):
After selecting the appropriate battery, check the communication between the inverter and battery.
You should be able to see the battery’s state of charge, voltage, temperature, and other key metrics on the inverter display or monitoring platform.
If the inverter doesn’t seem to recognize the battery, check the wiring and communication settings. Ensure all CAN or RS485 cables are securely connected.
6. Initial Testing:
Test the System: Once the system is configured, test it by running a few charge and discharge cycles to make sure everything is operating correctly. Monitor the inverter’s display for any error codes or warnings.
Verify Battery Charging/Discharging: Ensure that the inverter is charging and discharging the battery as expected. The inverter should manage the charge cycles based on energy input from the solar panels, battery state of charge, and energy demand.
7. Remote Monitoring (Optional):
Connect to Remote Monitoring: Many Deye inverters support remote monitoring via a mobile app or web portal. You can check the performance, battery status, and other key data remotely.
Follow the manufacturer’s guide to set up the remote monitoring features and ensure the inverter is connected to your local network if needed.
8. Troubleshooting (if necessary):
If you face any issues, check for error codes in the inverter’s display or the mobile app. Refer to the user manuals for troubleshooting steps.
Common problems can include issues with the battery's communication, wiring, or parameter settings.
Important Notes:
Consult Manuals: Always refer to the manuals provided by both the inverter and the battery manufacturers for detailed, model-specific instructions.
Firmware Updates: Check if your Deye inverter requires any updates .
