1. Restart.
2. If you observe a module LED is off, try to
bypass the module on both comm. and
power side and see whether rest modules`
LED could be on and green. If so, then
please change the BMU of the bypassed
module. If not, further bypass the next LED
off module and repeat the process.
If problem remains, contact Pylontech
service engineer.
1. Check the connectivity and reliability of
the comm. cable between BMS and battery
modules.
Restart.
2. If problem remain, contact Pylontech
service engineer.
1. Change the BMU of the RED LED module.
If problem remain, contact Pylontech service
engineer.
1. Restart.
2. Change the current measurement board
3. Change the CMU or BMS.
4. If problem remains, contact Pylontech
service engineer.
1.
Change PMU
If problem remain, contact Pylontech service
engineer.
1.
Completely switch off inverter and
battery system. Make sure DCBUS has no
voltage.
2.
Switch on each BMS first before switch on
the MBMS. After the battery system finish
self-test (require ~3mins), switch on the
inverter.
3.
Change the relay or BMS.
If problem remain, contact Pylontech service
engineer.
1.
Change the RED LED module`s BMU.
2.
Check the temp. sensor cable connect
between BMU and battery pack of the
connectivity.
3.
Change the RED LED module.
If problem remain, contact Pylontech service
engineer.
1.
Change the RED LED module`s BMU.
2.
Check the voltage sensor cable connect
between BMU and battery pack of the
connectivity.
3.
Change the RED LED module.
4. If problem remain, contact Pylontech service
engineer.
