EP Solar MPPT Tracer charge controller serial code

Following on from my previous post working out the EP Solar Tracer serial protocol, I’ve got code working on a Raspberry Pi. It’s even validating the CRC checksum.

EP Solar MPPT Tracer charge controller serial interface

I’m currently involved in a project to set up a solar powered wireless station and wanted to remotely monitor the battery charge process. I looked into a number of charge controllers to see if any of them could be connected to a computer. Many of the controllers have ethernet and built in web servers, but these come at a cost.

The (relatively) cheap chinese made EP Solar Tracer MPPT Solar charge controllers have an RJ45 interface for an MT5 remote display which means that there must be some way to get data out of the charge controller.
