This thread (and a couple of others here) show there is a small amount of interest in monitoring using a Linux host. Has anyone started work yet? Like others I have a Linux box that is on all the time that would be ideal to handle the data collection.
Installation at my house is likely to begin in a couple of weeks. I'm getting a pair of Sunpower SPR-3300x invertors (which are apparently re-badged Xantrex inverters). The limited information on the Sunpower site gives me some hope that the rs232 connections and protocols might be the same.
One question on opto-isolation & Xantrex ... the fishbowl info page still has the "absolute requirement that you purchase and install an opto-isolator", but in
this thread Solar guppy said "<i>The CPU's are isolated from all the inverter electronics internally so from a protection stand point, the RS232's are effectively isolated and no I do not use another level of isolation and never had issues, even in lightning capital of the US here in Florida</i>". So did things change with newer Xantrex invertors?
