Hello,
When I charge a 200Ah lithium battery with a Multiplus 12/500, after a while the charger switches off and the "high DC ripple" alert appears. Could not charge it fully. I took the battery and the Multiplus out of the electrical system to connect them directly to each other, but the problem persists ...
So I imagine the error is either from the battery or from the multiplus?
Have you ever run into this problem? What do you think is the cause?
thanks in advance
