Re: Photovoltaic inverter monitoring or logging software




Dear Bret,

If the instrument has a RS232 interface probably it sends information in ASCII format.

It would be important to see equipment manual to know how this communication works.

Do you have a cable for conection of the instrument with a computer?

In some instruments you set, by the keyboardthe the sending of data over serial in a unidirectional way, ie, the instrument only sends data but does not receive commands.

Other instruments offer the possibility bidirectional communication, receives commands and sends information.

Send more information about this instrument, link to download the manual, and we'll see if we can help you.

Best regards,
Markos

Hello.

I am wondering whether anyone on this list, has any knowledge or experience of software that runs on Linux, preferably Debian Linux, for monitoring/logging electricity output from a photovoltaic inverter.

In searching in the Debian packages facility, the only package that I found, was solarpowerlog (0.23a-2), for Debian Linux v7, and the package is apparently for only Solarmax inverters.

I am seeking software that will interface with Rewatt inverters, which apparently have an RS232 interface socket. The inverters come with a software disk, the supplied software apparently being for only MS Windows.

I have recently been told information about photovoltaic systems, that increases my curiosity, increasing the incentive to have continuous monitoring of output.

Thank you in anticipation.
