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,
Updated on NOV 29 2021
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
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

Have to watch this video ~ Really ~ Really important
Most solar users are fooled by the micro inverter company,
Their advertizing is a fake ~
Typical FAKE INFORMATION
String Inverter
The pannel has connected in series. when some panel has shaded, it will affect on VOLTAGE not current. so, and, power will be by-passed on the the shade panel, total power output will be 100-100-100-50, the drawing for string inverter is 100% fake, or they just ignore the role of by-pass dioe,
Micro Inverter
when partial shading, it will reduce the voltage not current, and there are 3 or 4 sections in a panel, and each section has by-passed using a diode. if the panel has 3 sections (60-72 cell), voltage will drop to 2/3 level. Even shade a SINGLE cell. if 36~39V system voltage drop to 2/3, the votlage output with the same current will be 24~26V. UNFOTUNATELY, most micro inverter need higher than 27V, effectively 29~30V. So, Even 1 CELL has shaded, MI will just output 5-10% power which has generated by the diffusion light. so, 100-100-100-10 are the correct otuput in the drawing.
NEVER FOOLED, Practically, String inverter will ouptut more than 99% of MI system, even better long term.
If someone ask, when MI system is better ?
I want to say when have small sections. you need at least 6+ panels for start-up and 8~12 panels for the best efficiency in a section (similar light condition). and, the most string inverter has 2~4 MPPT line. if there the section size is less than 6, can not use the section in case of string inverter. and, if the section number is more than 4, need multiple inverters. example,
BUT, micro inverter system free from this requirments.
It is the real advantage of micro-inverter system,
Any other explanations are 99% BS
