Hi,
I have some issues with my multiplus 12/500/20 in battery charging mode. While charging a lifepo4 battery the multiplus shuts down the charging current when increasing battery voltage of 13.8V.
Since battery voltage drops with absence of charging current, the cycle starts again and again and again. Therefore battery can’t be fully charged
Any ideas what could potentially trigger the current shut down event when increasing 13.8V? (Multiplus is set to correct lifepo4 mode with the dip switches).
Further info: In the system there are also some loads, which lead to the negative currents. The system is also connected to a Victron solar charger which fully charges the battery without any issues.
Thanks for any ideas.
