SMA Solar Inverter readout

This is a project to read out a solar inverter from SMA (model 5000TL in this case) via Bluetooth. It displays current power, today's yield, and total producrtion on an attached 16x2 character LCD. The display updates every 10 seconds.

For details, see the posts on the JeeLabs weblog: part 1 - part 2 - part 3.

Built with an STM32F103 board, a soldering iron, Mecrisp Forth, OpenSCAD, and an UltiMaker.
