Will this work?
A friend has an off-grid property that is served by a Canyon Industries AC
turbine w/ T&H controller. Output is around 2kw. Of course, no surge capacity
there. He has recently moved there full time and is Vrbo’ing one of the cabins
so power needs have increased.
What I have done previously in these situations with low Kw AC turbines is
install a battery based system and Iota chargers that are powered from the
turbine. That’s always worked well, BUT now that we are disciples of the
Discover AES/XW pairing I thought I would try this:
1) Connect the turbine’s output to AC2 and use Gen Support to enable loads
above 2kw or surges. That’s placing a lot of faith in Gen Support, and if it
were to not respond quick enough, well …trouble. The site is six hours away.
Then my friend tells me that he would like to throttle the turbine down during
the summer to conserve water, reducing output to .5-1kw. So, I got to thinking:
2) One inverter for charging only. One inverter for power output only. Charging
inverter communicates with AES through Xanbus and is connected to a
Gateway/Insight so that I can remotely adjust AC2 input current to scale with
seasonal turbine fluctuations. Neither inverter is Synced or knows of the
other’s existence. Output inverter gets a SCP for basic control and
monitoring. Battery bank is connected to a Discover SOC monitor.
I guess my questions are: Do you see any problems with this arrangement? Would
having what amounts to an external load (the output generator) trip things up
since it’s not communicating w/ the batteries? Could/Should I include the
output inverter in the Xanbus loop? And/Or can I connect the output inverter to
the Gateway device since it has two inputs,
Xanbus 1 and 2.
I’ve tried to reach Schneider to speak about this to no avail. Great product,
not so great support.
Thanks in Advance,
Michael
