FYI...
Every [Midnite] SMA E-Panel comes with a shunt trip breaker. SMA
requested this when they asked MidNite to design an E-Panel for them.
You will need the battery disconnect module to go with each E-Panel
though. The battery disconnect modules connect to the Birdhouse and to

Hey Steve,
Yes I'm reading that code article closely and I think its open to
interpretation. If you consider PV circuits to include the battery based
inverters, you would need to include them in rapid shutdown.
For some reason I thought it applied to all of the DC conductors,
including the batt
Mac,
Do you mean to ask for a way to shut down the Sunny Boys connected to the
Multicluster box?
Sunny Islands are not applicable to the rapid shutdown requirements. They are
not PV.

I completely agree with you and the "snail trails" will effect the
performance sooner then later, and the manufactures a kicking the can down
the road. We are also a small scale 42 watt to 110 watt module manufacture
and cracks are something we avoid at all costs.

Hi Wrenches,
I am working on a rapid shutdown design with an SMA multi-cluster box with
6 x 6048 Sunny Island Inverters, 2 per phase. I will be utilizing a
Midnite system for some roof top combiners. Is there a way to shutdown the
Sunny Islands via communication from the Midnite rapid shut down

Unfortunately snail trails are a clear indication of micro cracks that will
in time open up and degrade the output of the module substantially. They
may not have a performance problem yet , but give it time to show up! It
usually takes awhile for the snail trail to appear, the micro cracks

I am under the impression that a manufacturer module power output warranty
is just that - a warranty to guarantee the power output at a certain minimum
level unless a warranty exclusion occurred such as physical damage,
incorrect installation, etc. So, if a module is producing zero power it
The reason behind this rule, going back through some history, was to
reduce the possibility of a nail penetrating hidden conduit (conduit
behind a wall). Since the conduit is exposed/visible, the chances of
that action happening are small to none. So, the installer is saying
that a literal inte

We used to use Sharp but now its Trina, containers of 250 watt modules, data

story goes debates there data so that is true it softens the blow a little. I
have seen some another brand that are cracking p
