[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

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
