Shema 50V problem.pdfI have a strange problem on a ship with a 24v system. When checking the electrical system, I found that if everything or Multiplus, MPPT, etc. is connected, apart from the negative consumer and the starter battery are also connected to the system, I can measure 50V on the negative cable of the consumer and the positive pole of the consumer batteries . If I remove the plus of the starter batteries, I measure normal about 24V. I don't think that's normal and it looks like a hidden series connection to me. If EVERYTHING is connected, the system has normal 24V and the 50V are no longer visible. Maybe I'm making a mistake and don't see the forest for the trees. Does anyone have any idea why that is?
