question

For a new pack thats normal. It needs to balance. Off grid makes this more difficult as it needs time and usually on grid you could set it to keep charged.

Just let it be and try leave it at full charge as long as possible.

On the mppt, use the preset lithium, then tweak the voltages. The charge profile there has equalization and temp compensation. So not set up totally right.

The system if it is BMS controlled will onky charge when told to do so. And on some systems the Pylontec batteies keep themselves at 98 or 99%. Especially when "floating".

Have you followed a the required settings on the pylotec victron page for the basic offgrid?

Hi @Alexandra . thank you.

yes i followed all the victron / pylontech settings. We do install many of the configurations with Victron + Pylontech UP5000. ALL the others go to 100%.

for the mppt settings , I generally do not use the lithium preset because absorb and float are far hugjer than what pylontech requires. but anyway as you mentioned, with the pylon to victron datacable to the gx , the pylontech bms takes over.

the equalization is part of the page but off of course.

what i don't like is that due to this, i notice a larger voltage difference between cells when charging. it does not seem to balance the cells .....

i am closely following it...

thanks anyway for your input ; appreciate

It is normal, as per manuals.
