We were discussing remotely turning on and off the inverter itself like
with the Outback's remote on/ off terminals. Magnum only has their
remotes which aren't compatible with other systems.

Bill said one thing we ALL need to listen to, that is untill someone asked
it appears the renewable energy industry was not at the table. We need all
to be asking why and asking for change, also asking the AHJ where it is and
to clearify, sometimes thats all it takes. I bet that of who wa

HI Pat;
No disrespect in either direction. I always appreciate everyone's views.
Larry's Gigavac solenoid looks good too, but my read of 690.71 looks
like I still need an OCPD within 5 ft of the batteries, as well.
I'm already using substantial Midnite products for the actual "PV

I've been promoting the use of the remote on/off terminals that are
available in most inverters, which can be connected to the AUX in the
Birdhouse. For a very minimum effort and cost, the inverter AC output would
be shutdown when the rapid shutdown is activated. I think using the remote
on/off te
As a side note to this conversation, this brings up an advantage of the
Tesla Powerwall battery – my understanding is that it will turn off
immediately at the Powerwall battery when disconnected at the inverter.
This is another nice benefit of having DC-to-DC conversion smarts in the
Powerwall.
MidNite's Rapid Shutdown Sustems are UL listed.
If you have any questions, please email Ryan at r...@midnitesolar.com.
Ryan said we were actually having a webinar on this subject later this
week, too.
No solenoids so no night tare loss on the battery side or the PV side.

Hi Ray
Well you got me there
I meant no disrespect to you personally.
I think as a whole the code making panels do their best to keep up.
If I missed some of the particulars
Please excuse me.
And I guess it would be more useful to offer a workable solution
Maybe I've missed some of the details but
All right Larry, that's an actual start to a solution. My comments:
1) We already have had a solution for the array side using a Midnite
Birdhouse and Midnite rapid disconnecting combiner box. (The /PV
Circuit/ of the "/PV system circuit/" so I wasn't questioning that)
2) Who is the supplier

So Pat, you stated "/There are simple ways to work around these
issues/". Actually, the major off grid inverter manus do not have a
solution for this ( Magnum, Outback, Exeltech, Schneider, SMA)
Can you show us an example of a UL listed system that has multiple
inverters (over 8 kW cont.), with

Hi Bill;
First, I didn't intend to "shoot the messenger". I have appreciated
your many contributions to the PV industry, and enjoyed your education
courses over the years. Thank You.
However, 'PV system circuit' is not 'self defined' as you stated. By
that same interpretation, a single GT sy
Dear List,
Maybe it's an over simplistic opinion, but shouldnt all sources be
disconnected rapidly in an emergency situation.
We can always do better than what the code requires. I get frustrated when
people go to the book, (and try to hide behind the text). instead of
thinking through real life s
Ray,
I guess I have to step in after that acknowledgement. PV system circuit is a
self-defined term and therefore cannot be defined unless you are going to
develop a meaning that is different from the self-definition. It means ANY
circuit in a PV system. This includes battery and stand-alone circu
Greetings Esteemed Wrenches:
I've just heard back from our inspector here in Colorado, and we are
still being required to disconnect the batteries under 690.12. No where
in 690.12 are batteries mentioned, nor in the appropriate 690.71 section
that deals with batteries. The entire reasoning b
I've rented pipe and cable locaters at tool
rentals before. They can be tricky, but can also give good results.
