This repo has a few different implementations and tools for communicating with EP Solar Tracer charge controllers. This has been tested with Tracer model 3210A, but should work with any EP Solar Tracer model that uses Modbus RS485 and MT50 displays.

This Git Hub repository contains the solar powered website content and will evolve as we go along.
