I have requested a detail information abut LCF-064-1P,
Enphase - datasheet only
Manufacturer - can not provide it because customized item
No more solution, I have decided to return the filter on Enphase,
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 checked GTX-2300 to remove it.
the coil configuration is the two-in-hand winding, it is good for common filter becuase lower leakage
but, not good for differential. it means, it is not much useful for me.
so, I have removed it. and, reduce 0.5mA leakage current & 10mOhm Resistance Loss
It is similar situation, RP230-30-10-S have 60dB 50/50 insertion loss, but, can not block
the signal from next door, because too quiet in background noise, and no one use PLC devices.
so, just Envoy signal can be detected too easily.
so, I have detected to install a differential filter using ferrite
Ferrite core is B64290L0082X065
and, look the direction, it is the coupled differential mode, and 2 pass
over one day, verified, 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 5A. so, I have tried on single pass.
at least, I need 10A 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.
It is happening becuase too quite !!!
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
