Guest guest Posted August 18, 2011 Report Share Posted August 18, 2011 Hi, the dirty electricity generated by the converter goes also backwards into the panels. So you will have to fix one of these gizmos to the wiring to take care of the problem. dietrich In einer eMail vom 15.08.2011 15:48:27 Westeuropäische Sommerzeit schreibt delyme@...: Hi, I should warn you that I struggle with most cogitive tasks, so I might be asking a really dumb question. Anyhow, we are considering solar powers panels on our roof. I've searched previous posts and seen that the invterter/converter is a source of dirty power and should be housed in a wooden box lined with aluminium foil. The panels would be on the roof but not directly over the main sleeping or living area. However the only way to get the generated power to the export meter seems to be to go under the living room floor. Wondering about the potential risks and whether I can minimise them. I have relatively mild EMS, well, compared to what I used to have, (and on my scale of health problems it's lower ranked) but don't want to make it worse.

Guest guest Posted August 18, 2011 Report Share Posted August 18, 2011 It is very risky unless you are only using it for a DC system (batteries and DC lights... and make sure the battery regulator is not the " smart " pwm kind. I think the new micro-inverters are not as horrible, but don't be surpised if you have to leave the house when the sun is up. Foil shielding is not sufficient and you need very good filters properly bonded to the shield. You need to filter both the AC and DC sides. If all the solar stuff is far from the house you can just use a military type filter, with RF grounding, on the AC side.

Guest guest Posted August 19, 2011 Report Share Posted August 19, 2011 , housing the inverter in a foil-lined box will not help. The dirty electricty is on the wiring an the RF will be broadcast throughout the building from the wiring. Attempting to filter will damage the inverter.

Guest guest Posted August 20, 2011 Report Share Posted August 20, 2011 Ok, thanks Bill Bruno, dietrich and Shivani. Guess I knew it was a long shot and whatever I did I could never be sure it wasn't impacting my health in some way. > > > , housing the inverter in a foil-lined box will not help.

Guest guest Posted August 20, 2011 Report Share Posted August 20, 2011 A couple of links about inverters, filtering and electrical noise: http://www.power-eetimes.com/en/dc-filter-helps-reduce-solar-inverter-noise.html\ ?cmp_id=7 & news_id=222902292 http://www.windsun.com/General/PV-EMI.htm The details in the second link were written by an engineer. I believe someone on this list once mentioned that " Sunny Boy " inverters seemed exceptionally clean. R.

Guest guest Posted August 21, 2011 Report Share Posted August 21, 2011 Hi R Thank you for the links on how to clean up grid tie inverters. I can confirm that some grid tie inverters can be very " noisy " (ie full of harmonics from 50 hertz right up to the long wave and medium wave radio bands) depending on their quality. I was not aware that " sunny boys " had a reputation for being " clean " but it would make sense considering their cost. I became aware of this phenomenon when installing and operating a low output grid tie inverter powered by solar panels recently as an experimental and feasibility study. There was also a worrying development that was observed during the course of monitoring the progress of my " green energy " experiment and that related directly to the possibility of adverse bio-effects on plants and animals. The solar panels and grid tied inverter were sited at my remote garage 20 metres away from the house. The grid tie inverter was mounted on the garage wall inside the garage. On the outer side of the same garage wall what seemed like a healthy creeper producing abundant foliage had been growing for some 20 years. Every year this creeper was seen to cover more and more wall and roof area of the garage, indicating a measure of health and vitality. The system was switched on around early spring during the time the creeper was observed to be budding and producing its leaves. Within 2 weeks of operating the solar panel grid tie inverter system all the now fully formed creeper leaves mysteriously began to drop off and within a few weeks all the leaves were shed. They were observed to be lying in piles at the foot of the barren stalks that once supported them The creeper after 20 years of prolific growth now seems to be " dead " . I don't know what to make of it. The obvious explanation might be that the " extremely dirty " electricity could have caused this adverse effect on the creepers well being. The professional skeptic on the other hand might offer the " chance " explanation that is normally touted addressing adverse health clusters around masts etc. that this healthy creeper decided to " die " in mid bud by chance from some other unrelated and obscure reasons. I have not observed any adverse health effects on me or my partner as we already sleep in a shielded environment and are at some distance from the grid tie system. The worrying conclusion that might be drawn from this observable phenomenon is that the installation of grid tie inverters in an effort to go " green " might need to be given very careful thought. all the best panayis zambellis luton uk > > > > > > > > > , housing the inverter in a foil-lined box will not help.

Guest guest Posted August 23, 2011 Report Share Posted August 23, 2011 No problem everyone. Mind you, I haven't tried these inverters myself, but I'm keeping them in mind for if/when I build an offgrid system/home of my own. Cheers, R.
