I picked up the 2022 version of the 40 amp Tracer when I got my second set of 8 panels. At the time I was
also really wanting to get a controller that had a good built-in display, and the new Tracer has that. I just
got done building a new harness for it, using better quality wire (mostly OFC) and an optimized design. The
harness also can be disconnected from the controller so it's not flopping around when handling the controller.
I haven't decided if I will be using this as a replacement controller, run both controllers in parallel to
boost max solar production, or possibly split the solar collection into two separate sites.
Another "hybrid solution" would be to connect one string (of four panels) to the LiFePO4 battery controller
to power a satelite station, and connect the other three strings to one or two Tracer controllers at the main
grid. This system is pretty modular, so it allows me to try out different configurations to find what works
the best, or is the best for a given situation. Standby current is only 40mA, just a bit more than the 2021.
