I'm bringing this thread back up for B&W Travel. Regarding upgrading a Flex 400 solar package. Bryan, install 2 additional panels on the roof and connect to the existing ports. Upgrade the Victron solar controller. This is where I'm not sure which one he needs. I believe it's the MPPT 100/50

Here is a wiring diagram.
