Midnite Classic data logger

stephendv Solar Expert Posts: 1,571 ✭✭
I've got my classic logging to a local mysql database and also uploading the data to cosm.com (a free data logging and graphing service). It's part of my Island Manager code which includes the sunny island logger, but you can use the files separately to log data just from the classic. Mine data is here: https://cosm.com/feeds/75889
The files you'll need are:

The whole library:

And if you want to log to a local mysqldb, then also:

If you want to log to cosm then you'll need to setup an account and create a feed and 3 datastreams with the same names I used in classiclogger.php.

    The interface to the classic is progressing nicely, added a new feature where the Raspberry Pi will monitor the actual return amps going into the battery by reading the shunt connected to the Sunny Island, and then it will terminate absorb on the classic based on this value.

    Return amps into the battery have been set at 3.5A.
