ABB Aurora protocol (also used by former PowerOne in their Aurora Inverters) for communication with inverters and other devices

Introduction

Aurora protocol is used by ABB to control/monitor their power devices (inverters, central inverters, etc) over a RS485 bus. Usually inverters are capable of Aurora Protocol as well as Modbus RTU protocol (ABB sells a converter from Modbus RTU to Modbus TCP/IP).

This library intends to communicate with ABB Inverters using RS485/Aurora Protocol. Most of commands here were derived from an old document from Power One (this company was acquired by ABB year ago) and others were derived from projecs like aurora monitor and Linux Aurora program from Curtis Blank.

A documentation of the Aurora Inverter Communication Protocol can be found here.

Original work

Original arduino sketches (example provided) were originally wrote by Mr. Davide Rosa who was kind enough to give me permission to modify as a library and share under LGPL v2.1.

Originals can be found on Davide's page.

New Products

Please notice that newer product report model codes not recognized by this library yet. Please, send pull requests or open a issue with register values returned by your product and its model and I will be glad to merge/implement it.
