Gday, My question is, I currently have solar controller with a connected load output, in my caravan. I’m not sure what is connected to , but obviously small draw led’s etc. I am upgrading the system to lithium, and will upgrade the solar controller to a Victron mppt of similar amperage (45amp) Most solar controllers now, do not have load outputs, only batt and solar. What would I do with the pos and neg load output wires if I upgraded the solar controller? Some have suggested connecting them to the battery connection on the controller. Is this advisable? ---

I would not connect them in the same terminal unless you are sure the wires are smaller than the terminal holes. If I was doing this there are 2 options. 1. Put a connection block by the MPPT, connect the existing battery and load wires to this and add a new short wire from the connection block to the MPPT. 2. Extend the load wires to the battery with their own fuse and isolator. ---

That is great advice, running the wires direct to the battery will be problematic due to the cabinetry in the caravan. I will look at the connection block. Thanks for the reply. ---
