Hi,
last summer I installed a fairly easy setup:
- Cerbo GX MKII
- 2x MPPT 150/35
- 1x Battery (Felicity Solar with Pylontech compatible BMS, connected via CAN to the Cerbo GX)
The setup works quite well, however since it is installed in a garden shed, the temps now dropped below 0° C a couple of times.
I konw that the battery’s BMS has a low temperature protection and therefore I was not surprised to see the message “ESS #3 BMS disabled charging” or “ESS #4 BMS disabled discharging” if the battery is empty). However the reported temperature of the battery has once again risen to about 8° which is plenty above what the manufacturer says is fine for charging, however ESS #3 stays.
If I look at the Remote Console of the Cerbo GX it also shows ESS#3 on the main screen. However, if I go to the Pylontech Battery and select “Alarms”, all Alarm states say “OK”. I would have imagined, that the LowTempWarning would have tripped?!. The battery itself also shows no alarms on its LED-display.
Where is ESS #3 pulled from and does it need manual resetting?
regards,
Darky
