Hmmmm. Very thoughtful idea..... Considering this.... Still, I'd like to
see the net production.
I've an e-mail in to John Berdner-- he may have a Plan B I was not
previously aware of. I'm hoping the monitor that transfers data via the
power line does become available soon. I have several other clients who
could use this.
In spite of minor problems with the inverter, the web site and delivery on
this monitor, I am at the head of the cheerleading section for SMA
products. They are well built and work with minimum problems.
