Dirty Electricity Reduction

[Kenny_]

If the tv runs off an antenna most likely it will affect reception, definitely the stereo if using FM or AM. But who uses AM anymore, But like I said 10 to 15 feet away you should be ok

Interesting....I might have guessed that but have not had the opportunity to experience it.... TV is mostly streaming, but do have an antenna on the roof and the Stereo I use FM pretty much 24/7 and it's already a bit staticky....

I think we have 20 computers going in the house plus printers, scanners, ups units, routers, ethernet cables all over the place, 2 large wifi routers, 5 wifi repeaters.

Solar equipment never had a chance to compete in that emi generating pool.

interestingly, the "AM Radio as a measuring tool" does seem to work ... I was able to walk around the house with it set to 87.0kHz, and found:

- many wall-warts and other SMPS devices threw off noise that registered on the radio
- my Magnum 4024 (LF) inverter threw off noise (inverter located in separate power shed)
- my MPP Solar (HF) AIO inverter threw off noise (inverter in hand-truck solargen)
- solar panels (the wiring) threw off noise

I got tired of positioning the radio in three dimensions around each source, as it is a "blunt" measuring tool.

A higher-end gaussmeter is able to measure in all three directions at once, and has sensistivity (per meter) to various ranges of EMF/EMI, so clearly these are the better set of tools, but they start at $100's, and go to $1000's of dollars. The AM radio trick was pretty much free, and it does work, although I can't yet fathom why SMPS's and other power circuitry are throwing off so much interference that an AM radio picks it up.

And yes, the solar panels had some involvement, in that their power blocks mounted underneath did not radiate, but the wiring from the blocks clearly did, using the AM radio to measure things. I only had a few solar panels mounted on the power shed, and not entire roofs full of dozens of the things ...

That is "dirty power", which is more of a characteristic than a perjorative term, as you can have an inverter throwing out "clean" power, and every SMPS in your house throwing out "dirty" power in the form of THD.

Tons of research to continue wading through, but it looks like "electrical hypersensitivity (EHS)" could be a thing for some folks, and I'm guessing that it's EMF/EMI (the harmonics, or THD) and RF/RFI (all the wireless comms) that they'll need to mitigate, depending on their level of sensistivity. I clearly have no sensitivity to any of this, so there's nothing for me to mitigate, but there could be some who do need to put effort into it.

On the other hand, I didn't know I had an indoor air quality problem, until I started monitoring for it ... the mitigation there was to open more doors and windows, as often as I could. I live in the country, so this is no help to those who live in the city ... opening a door/window could make air quality worse for them.

We can't fix this EHS issue with a pure sine wave inverter with low THD, or being off-grid with inverters, as our multitudes of house electrical devices are throwing THD right back out. But, there do seem to be other ways to mitigate for EHS sufferers, and I hope OP finds those ...

I’ve heard of cows not doing well under high power transmission lines (mostly lactation related) so I wouldn’t call B.S. on it.

On the air quality thing…I’m installing ERVs in my workshop (plus regular woodworking air filters) and all future super tight buildings. I plan on I eventually building a “dirty” shop too and it won’t be as tight and will be kept just above freezing in the winter. No AC for that one. Lots of fans and squirrel cage extractors.

Welcome to the modern world absolutely everything throws off so much interference that if you think about it it would frighten you.
Back in the 80s amateur radio and DXing was fun, today it is almost impossible.

This is one of many many reasons I don’t want a “smart home.” WiFi is bad enough. Now you have at least one additional wireless network bouncing around inside and lots of folks have several.

I wish they had more devices that accepted networking cable or at least standard WiFi. I don’t need to turn on lights by farting in a specific rhythm but I would like alarm listeners and a few other odds and ends.

I don't think anyone is making jokes or being critical of you.

No, I think that is pretty much what is happening.
That will probably be their one and only post.

On a relatively basic biochemical level, there are voltage potentials going on at all times, inside and outside of each of your cells. Think about every cell, skin cells, cells that make up your organs, nerve cells, brain cells, heart cells.

Ions, which hold a certain charge on there own build up in number, let’s say on the outside of a cell, thereby creating a voltage potential that can be measured, from the less number of ions inside the cell. There is a gate on the cell barrier that opens either when another molecule binds thereby opening the gate causing influx from outside to inside. These ions are potassium, calcium, et. al…things your cells need. Nerves function based on this influx down the arm of the nerve transporting signal to the end which triggers another nerve and so on for motor contraction, pain, brain response, etc. Even heart cells have to sync up based on electrical nerve contraction to work correctly.

Drug discovery devices utilize this to create drugs that work well or don’t, determine dose, etc.

There is a tremendous amount of electrical stuff going on inside the body very delicately working, points to a Creator in my opinion. Not saying I agree with the DE claim, but not ruling it out either. Haven’t seen heath effects yet, but interesting to think about.

AM, 87 kHz?
Or FM, 87 MHz?

This puts AM broadcast between 500 kHz and 2 MHz, FM 80 MHz to 110 MHz:

How the Radio Spectrum Works

AM radio, FM radio, CB radio... These are all different chunks of the radio spectrum. Find out about the thousands of different uses for radio waves!

electronics.howstuffworks.com

It is something I've dealt with, getting products through EMI testing for FCC compliance.

Switch-mode supplies produce square waves around 100 kHz. The harmonics extend to 100 MHz and beyond.
Wires and PCB traces in the product are inefficient antennas at 100 kHz, more efficient at radiating power in the 100 MHz range - power cord is similar length to car's FM antenna.

What I had seen was a hump with many peaks in the 75 kHz to 150 kHz range. Thought it was digital switching, turned out to be SMPS "fast snake" power supply. I made a common-mode filter which knocked it down. Another guy altered the grounding and decoupling in the product where DC power cord connect, also fixing emissions, and that solution was adopted.

An FM radio would receive signals in that range, whether it affected audio would depend on modulation of the signal, whether it demodulated to audio (FM, frequency modulation, has to jitter back and forth carrying an audio tone.)

As for AM radio, the antenna is a ferrite stick with wire would around it, a solenoid. (A wire as AM antenna would be 100 meters long.) So this antenna in the radio is set up as resonator with a tunable capacitor. It would be affected by magnetic near field (in addition to propagating EM wave far field.) That could be how AM radio picks up SMPS when close.

We used to use AM radio when traveling, and it would hum when near utility substations. Magnetic leakage from transformers. Which is something I deal with in lab instruments today.

It's all true because some click bate YouTuber says it is.
I would hate to live my life with so much fear.
Just buy the best inverter you can afford that suits your needs.

I dont know enuf to know the truth about DE..but I will post it on my worry list in life .

Right under the following…....

Decades of too much booze…
Decades of heavy smoking…( quit 5 years ago)…
Enough fatty rare Ribeye steaks to make up a cattle herd…
Youthful drug use….
Vienna Sauages and soda crackers while fishing ..
100 times the safe UV exposure spent on docks and boats,
A few thousand bacon and egg breakfasts…With real butter..
Tons of Fried shrimp and Raw oysters..

The list could go ….I’m still here….feel good…but I have slowed down Abit…

At this point I have set life on cruise control…what will be ,will be..
I’m no longer able to process all the warnings about everything…

Does anyone have any experience reducing the dirty electricity (DE) caused by solar inverters?

I am wanting to go solar, since paying $850/month on electricity here in Orange County, California is insanity but I have health concerns over the dirty electricity caused by the inverters.

I already have stetzor filters in my house that help reduce DE currently caused by my appliances, etc, but I am not sure they are enough to filter out the DE caused by a solar system.

Here is an explanation on what dirty electricity is:
https://www.youtube.com/watch?v=ecwetD2zsms&t=30s

Here is one of several videos that I've seen proving that solar battery inverters cause high amounts of dirty electricity :
https://www.youtube.com/watch?v=1u1-kNHi-y8

Hello Lane77, If you install the filters at the main panel hey will be much more effective than placing them on outlets on the various circuits. I suggest installing two Stetzer fiters per pahse wired as close to the breaker bar and shortest wire run as possible. Sincerely Eric WIndheim BBEC, EMRS

There are no health risks from EMF from solar inverters. People claiming sickness from EMF are mentally ill. Ignore them and don't give them money.

I agree wholeheartedly.

It's also interesting that that's the guys first post on the forum.

This reeks of this post being created by the same dude, to bring "awareness" to this supposed phenomenon even existing (and because it's easy to rile people up, he can gain traction on the topic) and then him swooping in with his quote unquote credentials.

I bet he's a few hours away from replying to himself with the other account and then replying to that reply with a link to a book he wrote.
