How to connect GSL batteries to a DEYE inverter

To connect GSL batteries to a DEYE inverter, follow these steps carefully:

1. Hardware Setup:

Check Compatibility: Ensure your GSL batteries (e.g., GSL-HV51200, GSL-051200A-B-GBP2) are compatible with the DEYE inverter.

2. Wiring Connections:

Connect the positive (+) terminal of the GSL battery to the positive (+) terminal of the inverter.

Connect the negative (-) terminal of the GSL battery to the negative (-) terminal of the inverter.

Use the provided communication cable (RS485 or CAN bus) to link the battery to the DEYE inverter for data exchange.

Ensure proper grounding of both devices.

3. Inverter Configuration:

Power on the DEYE inverter and navigate to the Settings menu.

Go to Battery S

Select Communication Protocol → CAN or RS485, depending on the cable used.

Choose GSL as the battery brand if available.       If not, select Custom and manually set the parameters.

4. Battery Parameter Settings:

Set the following parameters on the inverter display:

Voltage Settings: According to GSL battery specifications (e.g., 51.2V for wall-mounted models, 100- 512V for high-voltage models).

Charging Current: Configure according to the maximum allowable current of the GSL battery.

Discharging Current: Set the limit based on your application needs and battery specs.

Charge and Discharge Voltage: Match these with the GSL technical specifications:

Charge Cut-off Voltage: 58.4V (for 51.2V models)

Discharge Cut-off Voltage: 45V (for 51.2V models)

5. System Testing:

Ensure all cables are securely connected.

Power on the DEYE inverter and the GSL battery.

Monitor the display for proper communication—battery status, voltage, current, and SOC (State of Charge) should display correctly.

Perform a functional test by simulating a load to confirm smooth operation.

6. Troubleshooting (if necessary):

If communication fails, double-check the CAN/RS485 cable connections and communication settings.

Ensure firmware is up to date on both the inverter and battery.
