Serial Connection to Solar Inverter

Submitted by Guest on Wed, 06/07/2011 - 13:13

I was wondering if there would be enough space/computing cycles left on the Arduino to also communicate to a solar inverter using the SoftwareSerial Library? I'm guessing that I can't use the main UART to connect, as this is used for programming?

Just that I think the inverter would give a more accurate reading of the voltage/current output of the PV array.

My inverter is a Xantrex 2.8, and I've found the protocol has been documented, and it runs at 9800 baud, so seems that SoftwareSerial Library should be possible.

Any thoughts?

I think this should be possible, its quite suprising sometimes how much you can get out of an arduino. Rob over at senecass has developed some software to communicate with Xantrex inverters which might be worth a look: http://www.welcomehome.org/senecass/software/powerguru/

Haha yeh that was the website I was using for reference! First thing I found from googling. Thanks for the feedback.
