I have requested a detail information abut LCF-064-1P,
Enphase - datasheet only
Manufacturer - can not provide it because customized item
No more solution with LCF, I have decided to return the filter on Enphase,
I am not sure the part is no good, or filtering is not enough.
So, I start to find the solution on my way,
I have reinstalled RP230-30-10-S and GTX-2300
BUT, it has too high line loss, so, I have disassembled & checked GTX-2300.
the coil configuration is the two-in-hand winding, it is good for common mode filtering, But, it has lower magnetic
leakage, so,not good for differential mode filtering. it is not much useful for me.
so, I have removed it. and, reduce 0.5mA leakage current & 10mOhm Resistance Loss
RP230-30-10-S have 60dB 50/50 insertion loss, but, can not block
the signal from next door also, I guess, my noise level at my home is too quiet and no one use PLC devices.
Yes, high SNR, so, just Envoy signal can be detected too easily.
so, I have detected to add an extra differential mode filter using ferrite
Ferrite core is B64290L0082X065
and, look the wire direction, it is the coupled differential mode, and 2 turns.
over one day, it can isolated successfuly, the expected core loss is 200-300Wh per year.
it is much less than 1~2kWh in GTX-2300-Y02.
This configuration will be saturated under 10A. so, I have tried on single turn.
at least, I need 20A because higher current will act as a noise, and will reduce the sensitivity of enovy.
and, I just need this inductor is working at the lower current (quite) zone.
This is final, configuration.
It is working well, now, my system has isolated completely.
and, no more cross-domain-traffic issue.
The cost of Ferrite & RP230 filter is just $80, and under $100 include tax & shipping.
It will working when system current is under 24A (around 20, IQ7+),
If want to apply on the bigger system, need bigger filter
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
