Multiplus 48/5000/70 slow charging

Hi!

I just installed the multiplus in my boat. After a short sail on my electric motor (100->67% soc), reconnected the cable back to shore.

After an hour it is still slowly charging in absorption mode. Do I have some settings wrong?

Charge setting is 16A.

@Mvmoock

Has the battery reached the set target charge voltage? We can't see from your screenshot what your battery voltage is, neither do we know what it is set to charge to.

State of charge, if you don't have a correctly configured BMV, can be a bit off.

Thank you for your answer.

For the information, I didn't change any settings for batteries voltages. Only the standard settings. The batteries are AGM.

Last days the Multiplus charged the batteries slowly to 100% (BMV setting). But never in bulk mode.schermafbeelding-2023-10-25-om-173210.png

I have still a question.

Sometimes the multiplus charges only slow like in this image. Sometimes, it charges quickly.

Is this because of the temperature? And is it able to change this?


Kind regards,
Martijn
