Hi guys, quick question.
Got 2 mid size systems with Victron components, everything is working great.
But I have one question I couldnt find an answer to, neither in the internet nor in the manual and I was searching for very long time.
Which ESS Setting in an DC coupled panel system is the most preservative for Pylontech batteries when the main focus is on feeding the grid only? (batteries are just there for a backup solution, but because of the stable grid, they are not really needed in practice)
Setup:
Multiplus II GX
BlueSolar MPPT 150/60
2x Pylontech US3000C
Again, everything is working great, but as Lithium batteries dont really like to get charged on a full 100% all the time I was wondering which setting in [ESS] menu would be the best to save and extend the lifetime of the batteries.
If I select [keep batteries charged] I minimize the "cycle movement" inside the batteries, but I have the problem of a full 100% and high voltage all the time.
If I select [optimized - without battery life] and put the SoC to 100% its the same in the end.
Wouldnt be the best solution for this an option which allows me to lets say keep the SoC on a stable 80%, with no further action? (just as a backup system when grid fails)
Please let me know which ESS settings are the most harmless for the batteries and for this type of scenario.
Thanks a lot,
All the best
Markus
