Inverter Monitor on Raspberry Pi for Samil Solar River Inverter via Serial

Perl script for monitoring an older Samil Solar River inverter using the RS232 (serial) connection, and uploading data to https://pvoutput.org.

See this blog post for a full explanation and instructions: Logging Solar Inverter Output with a Raspberry Pi.

This script has been modified from the original script hosted on the now-seemingly-defunct Solar Freaks forum.
