Got my new system running, main components:
MP5000, JK BMS, 10KW Battery Li ION (NOT lifepo4). Excess energy fed to the grid.
From time to time the following happens:
Battery status: nearly full (60v)
PV production low, ca. 500 watts
AC Loads go up to about 2500 W for some seconds only (no big consumer active in the household...). Grid consumption goes up too, of course.
Battery goes down to 51V.
Battery alarm goes on.
Then during about 10 seconds the battery goes up volt by volt back to 60v.
What could be the reason for this?
And: why is there an alarm at 51 volt? I didnt set it anywhere to this point.
