My yacht has 1400w of solar that runs through two MPPT to lithium batteries. The boat has a Quattro 12/5000. Everything works fine on the solar side. Float is set to 14v and that works well every time. But. If I plug the boat into shore power the system never goes to float mode. Batteries keep getting charged up to the alarm level at 16v. It used to work. No longer does. There may have been a software update between it working and not working. I’ve looked at the settings on the Colour Control panel but can’t see a fix. Help please.
