I have installed shortest wiring, and no overlap to avoid a crosstalk, and just put one Ferrite core to filter a common mode for wire organizing and 10cm overcome earth wires. It may affect on the high frequency, but, it is not our concern because LCF is for 110kHz L-to-L PLC & Noise filtering now.
 

Let me check what will happening,

Long story is short, It is not working

This is an error what I do not want to get..

I have requested some advice and, Enphase said

 

Avoid a magnetic PLC coupling by

  - Own enclouser :: it is related with a distance, but, -.-a

  - 12" distance between conductor  :: point to point is not important, parallel run is the key

 

Anyway, I have installed as

If I add an enclouser for the filter, I have to get a permit & inspection from local office. it become so complicated issue. and, I feel, so strange, the engineer do not understand what is the real problem.

 

anyway, I am not sure what is the cause why it can not block the signal from my next door, 

i understand as it is a customized part for IQ. Maybe it is just a issue of my part. 

 

while low current, Enovy is detecting the other enovy at outside.

IT is happening because my house has very quite in electric noise.

if not cut-out completely, the filter is not enough because still high SNR. 

 

 

Very good video what is difference between Mico and String Inverters

 

 

Micro vs String Inverter

 

 

You have to watch it before install a solar system.

 

Enphase MI system is much expensive than String inverter,

even more than Optimizer system.

 

But, String inverter system need 6+ panels in series, it means there is a minimum number of panels under similar sun-light condition. but, MI system do not have the minimum requirments, technically 1 panel.

 

so, if have small zone & multi zones (more than 2), MI should be better

except this condition, There is no advantage via the extra cost
