[RE-wrenches] Internet-based monitoring

[Joel Davidson]

Hello Wrenches,

The subject of PV system monitoring has been discussed before, but I want to 
get your latest recommendations. I have over 50 commercial PV systems in 
several states that I want to monitor on computers both at the site and at 
one central location. Some sites have more than one PV system. What 
internet-based PV monitoring system for multiple commercial PV systems have 
you found to be reliable, provides useful information for identifying 
problems and trouble-shooting, and is reasonably priced? What other 
attributes should I be looking for? And what should I avoid? Thanks in 
advance for your practical and sage advice.
