<p class="MsoNormal">I am going to be working with a group of high school students
this summer who have very limited prior solar experience. We will be
installing a small off grid PV system (1.9kW) and small wind turbine generator (400W
to 1kW). I plan on using three Morningstar Trimetric controllers, one to
control charge of the PV array to the battery bank, a second as a load control
relay, and a third as a dump control. I can connect all the Morningstar
controllers together on an RS485 bus and connect to the solar charge controller
via an Ethernet link to the local area network. The Morningstar
controllers will be monitored via a classroom computer, and they will be able
to give me Ahrs in from the solar array, Ahrs to the load, Ahrs to the dump
load, but not the Ahrs in from the wind turbine generator. My question
is, how can I add monitoring of the wind turbine Ahrs that goes to the battery?
I will need something that can get to the local area network. Wifi or
direct broadcast may be difficult because I have to go through the electronics
cabinet and two brick walls.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The only thing I can think of is to add a Tri or Penta
Metric from Bogart Engineering, which would duplicate the info the Morningstar
controllers would give me, but could add the Wind Turbine Generator as well,
but perhaps there is a better way.<o:p></o:p></p>

<p class="MsoNormal">Thanks for your thoughts.<o:p></o:p></p>
