I have a 2022 East to West Alta 2810KIK that came with a cheap Wayree charge controller shown on the attachment 1. Also has a 50W solar panel that I plan to upgrade down the road. I want to upgrade this controller to a Victron MPPT and lithium batteries. The wiring diagram on attachment 2 and the photo on attachment 3 are different. What am I missing as it seems there should be + & - battery, + & - PV, and + & - load?
Thanks in advance for help.

The WAAREE controller uses a common positive. Behind your panel, the positive from the panel, to the battery and to the load are tied together. The controller works using the negatives to do its job.

With a new controller, you will need to separate the positives.

Myself, I don't use the LOAD terminals. All my loads are direct to the battery.
