Photovoltaics and EMFs

Hi Stephen,

How does one know whether the inverter/wiring was installed correctly for clean frequencies on the occupant load side?  Is there a way to “check”?  

My inverter makes a LOT of noise (located in the basement).  It’s a Renovo.

> DC magnetic fields are found in the ground typically, that?s our earth?s magnetic field. Strength can vary if iron ores or other amplifiers are below the house.

> AC magnetic fields occur when there is AC flowing (current) through a wire. (considered low frequency EMF)
> AC electric fields are an indication of the presence of electrical pressure across a wire/area. (considered low frequency EMF)

> High frequency or microwaves are when the AC magnetic and electric fields combine to create EMF Electromagnetic fields. These happen within a few wavelengths out from the source where they combine to create one wave form.

> When converting DC to AC, transformers/inverters of any kind can generate a significant amount of AC fields, as well as VLF (Very Low Frequency Fields), which is the harmonic noise on the sine wave, which makes for non smooth waves, making your computer crap out. Proper installation of photovoltaics should hopefully resolve most of that since everyone wants clean power. That said, if your PV installer doesn?t understand clean frequencies on the occupant load side, you should have someone different install your PV. Some equipment is also worse than others. Measurements are required on all installations since wiring errors can also amplify these issues.
