Re: [RE-wrenches] Enphase monitoring picking up other systems

Ben:

 

I hope you installed a dedicated sub-panel to connect the inverters and Envoy.  
If so, find a filter to insert on the feeder to the sub-panel.  Digi-key has 
some models.  Install the filter and you should be resolved.

 

Enphase tech support can scan the bandwidth to detect interference and advise.  
They have been pretty helpful.  Good luck.

 

William

Subject: [RE-wrenches] Enphase monitoring picking up other systems

 

Wrenches,

I'm sure i read a thread on this list about dealing with this, i've searched 
but cannot find it.  If anyone recalls the subject line, please let me know.

 

We are dealing with setting up Enphase monitoring in neighborhoods with other 
Enphase systems nearby and these 'other' systems are being picked up by the EMU.

 

A few weeks ago we finished a 14 module (3.5kW) install and i plugged in the 
EMU to search for the inverters.  As it was picking up the first few inverters, 
it was showing several hundred kWh already produced???  Not bad for a 14 module 
system being in operation for 10 min!!!  (yes the inverters were new, out of 
the box)

 

After 30-40 min, the EMU had picked up 28 inverters in total.  There were 14 on 
the system we had just installed, and 14 on a house across the street that we 
had installed back in Nov'13.  I'm pretty sure it had picked up the 14 across 
the street before picking up the ones we just installed.
Funny that we can sometimes have communication issues btwn the inverters and 
EMU in some houses, and here we have EMU's picking up inverters across the 
street!?!

 

Anywho... has anyone dealt with this and streamlined a process with Enphase to 
remedy this issue?

 

Cheers,

Benn

Hi Ray,

We always add a dedicated PV 120/240 VAC Load Center to mount our Enphase
CB's in, and the 15A CB for the Envoy's receptacle. This has eliminated all
comm. Issues for us.

Funny the timing of the Wrenches list, just Saturday I added some Enphase
inverters to an existing GTB  Outback system.  The Enphase are not AC
coupled to the Outbacks, as I didn't want to get into the battery charging
issues, and the customer has plenty of PV relative to the battery size.
However, we're having a communication issue as well.  I'm guessing that the
Envoy can't be on the Outback side of the system with the Enphase inverters
being on the grid side.  So, is there an elegant solution besides putting
the Envoy on the grid side of the system  (which is out in the garage)  The
whole house is on back up, so no grid direct circuits are available there,
and the wiring is such that it would not be easy to change that either.
I was actually going to add a transfer switch to the Enphase circuit, so
that in an extended outage, the customer could have the option of bringing
in the Enphase inverters.  I have the Enphase breaker in the Outback Flex
500 box already, so at least that would be simple.

Since some of these are home builder's 'show homes' and new home builds,
there is the possibility that internet has not always been set up yet, so in

If "we" cannot remove rogue inverters from a particular Envoy, then we will

Enphase and let them sort it out.

 

We may consider the Array Gun scanner option.

Hi Benn,

We've run into these problems when simultaneously commissioning systems in
adjacent units of a housing development where we did PV systems on all
homes, and 2-3 homes are on one utility transformer. I'm a little surprised
that the Envoy picked up inverters from an existing system, unless those
microinverters were never associated with another Envoy. My understanding
from Enphase is that once they are "bound" to one Envoy, they won't be
easily picked up in a device scan. But maybe I'm missing something, or got
bad info from tech support.

We've definitely had to work with Enphase tech support on a couple of
systems to remove inverters from one Envoy, then do a device scan on another
Envoy, as August suggested. Another option is to spend the money for the
Array Gun scanner (SocketMobile CHS7xi scanner), and use the iOS Enphase
Installer Toolkit app to build arrays and "provision" the Envoy, sending the
inverter serial numbers directly to the Envoy, without need for a device
scan. Not sure if this is worth it at the $450 retail price for the scanner,
but if you can find one used, it might be. I recently was able to pick one
up for about $250 used.

Haven't yet had issues serious enough to require LCFs on residential
systems. Crossing my fingers on that one.

Re: [RE-wrenches] Enphase monitoring picking up other systems

[Nick Soleil]

Hi Benn,

Our customer service team can help you resolve this issue, and I am also
happy to speak with you about this.

That is a somewhat unusual scenario, because once an array of
microinverters has been communicating with one Envoy (EMU was the original
product name,) then those microinverters should be associated with that
Envoy.  For the scenario that you described to occur, the older site's
Envoy must have been removed or not communicating with it's
microinverters.  Since those older microinverters have not been
communicating with any other EMU or Envoy for a while, they reported all of
their production data to the new Envoy when you plugged it in.  The
situation you described can also occur when the Envoy or EMU had been
previously installed at another system and already was holding that data in
it.

If you want to remove the other devices from the Envoy, you can connect the
Envoy to a laptop or to a network, and access the local host page of the
Envoy by entering the IP Address that is displayed on the Envoy's LCD
screen into you browser's address bar.  Once you've accessed the Envoy's
local host page, you can delete the extra devices from the device menu.  To
access that menu, you will need to enter 'admin' for the user name and
'admin' for the password.

If the Envoy has reported those erroneous devices from the Envoy to the
web, then those devices must also be removed from Enlighten, as August
mentioned.

This scenario you described, with two arrays reporting to a single Envoy,
can only occur when the separate residences share a common utility
transformer.  If you are developing a large project with many homes or
apartments on the same transformer,  then we have some best practices that
we recommend, to ensure a trouble free commissioning.  You can view our
Multitenant Application Note online.

I would say that Line Communication Filters are not necessary for this
application.  LCFs are really designed for commercial scale projects.  We
have evaluated a number of smaller, 20A to 60A filters that are available
for filtering:powerline communications in single phase applications, but
they are likely not needed in your scenario.  That technical brief, Filters
for Single Phase Applications, is available on our website.

For commercial scale applications, some of these same design parameters can
come into play.  Our Envoy is limited to 600 microinverters, so a large
system may need to use powerline filters or transformers to isolate the
separate Envoy's communication domains.  You can read more about that in
our Commercial Design Guide online.

All of our US downloads are available at:
http://enphase.com/global/resources/geo_us/  The docs discussed are
primarily located under our tech briefs.

I'm being told that "we" (as opposed to "Enhpase") cannot delete or remove
rogue inverters from the Array Builder.  Enphase has to do this step.   And
if you just don't include the rogue inverters in the Array Builder you are
building for a particular system, you will still receive the production
data from the rogues.  (2nd hand info, so..?)

Louis,
Since some of these are home builder's 'show homes' and new home builds,
there is the possibility that internet has not always been set up yet, so
in some of these cases the inverters may not have been dedicated to a
particular Envoy yet.

If "we" cannot remove rogue inverters from a particular Envoy, then we will
likely just send the serial numbers of the Envoy and respective inverters
to Enphase and let them sort it out.

We may consider the Array Gun scanner option.

Anyone else have any feedback on this option?


Cheers,
Benn

Re: [RE-wrenches] Enphase monitoring picking up other systems

[Louis Woofenden]

Hi Benn,

We've run into these problems when simultaneously commissioning systems 
in adjacent units of a housing development where we did PV systems on 
all homes, and 2-3 homes are on one utility transformer. I'm a little 
surprised that the Envoy picked up inverters from an existing system, 
unless those microinverters were never associated with another Envoy. My 
understanding from Enphase is that once they are "bound" to one Envoy, 
they won't be easily picked up in a device scan. But maybe I'm missing 
something, or got bad info from tech support.


We've definitely had to work with Enphase tech support on a couple of 
systems to remove inverters from one Envoy, then do a device scan on 
another Envoy, as August suggested. Another option is to spend the money 
for the Array Gun scanner (SocketMobile CHS7xi scanner), and use the iOS 
Enphase Installer Toolkit app to build arrays and "provision" the Envoy, 
sending the inverter serial numbers directly to the Envoy, without need 
for a device scan. Not sure if this is worth it at the $450 retail price 
for the scanner, but if you can find one used, it might be. I recently 
was able to pick one up for about $250 used.


Haven't yet had issues serious enough to require LCFs on residential 
systems. Crossing my fingers on that one.

We are dealing with setting up Enphase monitoring in neighborhoods 
with other Enphase systems nearby and these 'other' systems are being 
picked up by the EMU.


A few weeks ago we finished a 14 module (3.5kW) install and i plugged 
in the EMU to search for the inverters.  As it was picking up the 
first few inverters, it was showing several hundred kWh already 
produced???  Not bad for a 14 module system being in operation for 10 
min!!!  (yes the inverters were new, out of the box)


After 30-40 min, the EMU had picked up 28 inverters in total.  There 
were 14 on the system we had just installed, and 14 on a house across 
the street that we had installed back in Nov'13.  I'm pretty sure it 
had picked up the 14 across the street before picking up the ones we 
just installed.
Funny that we can sometimes have communication issues btwn the 
inverters and EMU in some houses, and here we have EMU's picking up 
inverters across the street!?!


Anywho... has anyone dealt with this and streamlined a process with 
Enphase to remedy this issue?


Cheers,
Benn

Re: [RE-wrenches] Enphase monitoring picking up other systems

[August Goers]

Hi Benn,



You should be able to login to the Array Builder and select and remove the
micros that don’t belong. As long as the 14 micros that you do want show up
you should be good to go. When all else fails Enphase tech support will
walk you through it.



Best, August

[RE-wrenches] Enphase monitoring picking up other systems

[Benn Kilburn]

Wrenches,
I'm sure i read a thread on this list about dealing with this, i've
searched but cannot find it.  If anyone recalls the subject line, please
let me know.

We are dealing with setting up Enphase monitoring in neighborhoods with
other Enphase systems nearby and these 'other' systems are being picked up
by the EMU.

A few weeks ago we finished a 14 module (3.5kW) install and i plugged in
the EMU to search for the inverters.  As it was picking up the first few
inverters, it was showing several hundred kWh already produced???  Not bad
for a 14 module system being in operation for 10 min!!!  (yes the inverters
were new, out of the box)

After 30-40 min, the EMU had picked up 28 inverters in total.  There were
14 on the system we had just installed, and 14 on a house across the street
that we had installed back in Nov'13.  I'm pretty sure it had picked up the
14 across the street before picking up the ones we just installed.
Funny that we can sometimes have communication issues btwn the inverters
and EMU in some houses, and here we have EMU's picking up inverters across
the street!?!

Anywho... has anyone dealt with this and streamlined a process with Enphase
to remedy this issue?

Cheers,
Benn
