Hello all!
I installed a Victron system in my sailboat two years ago and I thought it was working perfectly; however, this year I was checking the system and it shows 16v at the system plus port. My system has the MPPT and DC loads connected to system plus. I also have the following installed: multiplus-ii 12-2000, cerbo gx, 2 Victron LiFeP0 160 AH batteries. Problem seems to be happening when batteries are full and balanced. Voltage settings in MPPT are correct. The only charging source that is running is the solar panel when I saw this reading. I wired this according to my suppliers suggestions and it seems to align with my bms manual. Has anyone else seen this and do you have any suggestions? Thanks.
