EG4 ELECTRONICS LV6548 Battery Voltage Calibration SOP
Product Information
Specifications
- Power Supply: 55.5V / 5A
- Communication Tool: RS232-USB cable
- PC Compatibility: Yes
Product Usage Instructions
Prepare
- Download and install the Communication Tool on your PC.
- Connect the RS232-USB cable to your PC.
- Connect the power supply (55.5V/5A) to the battery positive and
negative connectors of the Inverter.
Calibrate the Battery Voltage
- Turn on the Inverter, ensuring it is set to battery mode.
- Double click on the Communication Tool to start the communication tool on your PC.
- Connect the RS232 to USB cable to establish a connection between the Inverter and your PC.
- In the Communication Tool window, locate and select the appropriate COM port. Enable CRC (Cyclic Redundancy Check) if available.
- Send the command “BTA0” to the Inverter. The Inverter should return an acknowledgment (ACK).
- Adjust the power supply to 55.5V and send the command “BTA1055.50” to the Inverter. The Inverter should return an acknowledgment (ACK).
- Adjust the power supply to 46V and send the command “BTA2046.00” to the Inverter. The Inverter should return an acknowledgment (ACK).
- Change the power supply’s voltage to a different value. Send the command “QPIGS” and compare the return value to the actual battery’s voltage. They should be equal.
Frequently Asked Questions (FAQ)
Q: What is the purpose of calibrating the battery voltage?
A: Calibrating the battery voltage ensures accurate measurement and performance of the Inverter.
Q: Can I use a different power supply for calibration?
A: No, it is recommended to use the specified power supply (55.5V/5A) for accurate calibration results.
