12/200 alternator shut off

Trying to get my head around how the 12/200 operates and would appreciate any help to educate me ;)


The 12/200 datasheet shows that the 12/200 has a shutoff voltage of 11V which makes sense, but I am missing something in my understanding of how it works to stop overcharging of a lithium.


I also understand the purpose of the fuse to set the current limiting from the alternator (not sure how it achieves this though) - but again, am missing something to see how/when it shuts off the charge to the lithiums (and uses the lead-acid to dump into).


Anybody able to fill the missing gaps for me ?

Hi Daniel,


I have a similar issue. I have a 12/200 BMS on my Victron lithium batteries. I don't really use the alternator for charging as the solar fulfills most of my power needs. However, now in winter I noticed the alternator charging seems to be switching on and off after a few minutes. If I turn off the engine and start again the charging is back to normal but after a few minutes it reverts to switching on and off continually. Any ideas of the issue? Thanks in advance
