I configured my Setup with the help of this victron offical tutorial https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom


Problem:

Multi Plus shows always "Battery low voltage" warning.


Question:

What could i have done wrong ?


Thanks for the support

Hi! I am in the exact same situation as you. Did you manage to figure that out?

There is too little information provided relative to your question.

You can submit some CCGX information photos or the measured system battery voltage is a value, etc.

Good luck

Using VEConfigure3, look in to see/change your 'low batt' setting. Maybe under Inverter>'DC input low pre-alarm'. Ask again if you need help doing that.

Might not be the issue either, but you'll enjoy the learning experience. :)

Hi Inigodu and Oemmes,

Did you both read the section in the Pylontech Victron manual 4. VEConfigure Settings ?


"Due to the reliability of the grid supply and the behaviour of the sustain voltage threshold in ESS; you may wish to suppress the low voltage pre-alarm warning so that it does not trigger every day on its regular deep cycle. See ESS FAQ Q5 - about suppressing the low-voltage alarm."
