Good morning,
yeah, it is currently 01:23 in the morning and I have to ask because my MultiPlus-II 24/5000 show the first time a realy strange behaviour.
OK, here it is:
Since in the Winter it is hard to Equalize the Batteries (24V, 2940Ah), I rent once a month a SDMO HX6000 which worked fine for the previously 4 times. Yesterday I start charging because the batteries reached the DOD70% and all was working fine (13:52)
Just 30min ago (01:02) everything changed. I had to refill the tank and started the HX6000 and after some seconds the MultiPlus-II went from Bulk Charging (27,7V) into Equalizaton and lowert the Voltage to 26,6V. WTH?
My 4 BMVs (each SOPzS set of 735Ah has its own BMV 702 and a Balancer) showed that I have still -70Ah approximately, hence I have to charge at least 5-8 hours to get the batteries full.
The 4 previous times, the batteries where charged to 29,13V and then it switched into Equalizing.
What can have caused this strange behavour?
MultiPlus-II 24/5000 broken?
Thanks for your help
