Solar MD SS4143-11, Installation Manual

Page: 20 / 55

Fixed color with current direction based in shading
**For future development
When this state has been selected, the button shows illumination in a color based on the
user choice and flashing code based on the electrical current direction (charge / discharge).
The flashing code for charge goes through illumination interruption for 1 interval and slow
illumination for 5 intervals. The flashing code for discharge represents the opposite from
charge - study color for 1 interval and slow loss of color following illumination interruption.
Solar MD users refer to both as charging / discharging waves.
Firmware
BMS EX can store multiple firmware versions. Upon startup the bootloader will start the latest
version available.
How to Update
Logger V2 can update the firmware of a connected and communicating BMS via CANBUS. The
logger stores available BMS-Ex firmwares locally and can send it to the BMS as requested.
Firmware Update Settings
- Refresh Loaded Firmware info BMS: Press “Refresh”to see the latest BMS firmware
version that has been sent from the logger to the BMS.
- Check Available Updates: Press the “Check”button to see the latest BMS firmware
version available.
- Upload Available Firmware to BMS: If the BMS firmware version is lower than the latest
available firmware version then type in the firmware version you would like to upload in the
space provided and click “upload”.
- Write Loaded Firmware: Once the firmware has been fully uploaded from the logger to
the BMS (progress bar should show 100%) click the “write” button. This will start the two
step installation process on the BMS.
- The BMS will first verify the uploaded firmware, during this process the indication
LEDs on the BMS will flash slowly from left to right.
- The second part is installing the firmware, during this process the indication LEDs
on the BMS will flash fast from right to left. Once successfully installed the BMS will
restart. Verification of a successful update can be seen on the MyPower24 portal.
