Hello dear Victron community,
DEr Multiplus 2 and the MPPT charger show about 2V more DC voltage than the Pylontech.
I measured the voltage and found that the Pylontech voltage is physically correct.
This makes the SOC wrong and my relay assist is not working as it should The ESS goes into absobtion at 50% SOC.
I have gone through all the settings but can't find anything wrong.
Here is my system:
MP2 3000/48 CX
Pylontech US 3000C.
MPPT 150/45 3000Wp East/West.
and
the EM24
So I hope to get any hint from this community to solve this problem.
What do you guess? Software Hardware or User related problem. The system was running for 1.5 year. Than I got a new CX electronic board () and the newest updates.
The the problems start to raise with the sun.
with sunny greetings
Volker
