I don't let them X-ray my head ever since I was a little baby Physicist.  They say it is less than exposure from a sunny day (according to the X-ray machine salesman).  I say, nobody gets to irradiate me for profit.  My IQ is already down 10-15 pts from my neighbors mindlessly spraying Agent Orange (by another trade name) on their grass 5-6 times a year.  Can't afford to loose any more.   ;D

Yes, I think most will get what you're saying.  I serious, however, about not letting them X-ray me.

Thanks .

The lack of real info since the media is no longer free to report is the problem .

To get back to the new inverters topic:

MN product dev, can we please get the MN GT inverters to honor the convention set up by Magnum PAE inverters? The Magnum PAE (battery based)  inverters raise the grid frequency when the batteries are full, giving the signal to other GT inverters on the grid to stop producing power.  Please refer to http://pdf.wholesalesolar.com/inverter%20pdf%20folder/MagnumACcoupling.pdf for additional info. So the idea would be to get the proposed MN  GT inverters to honor this.

Just some BG info.  Are your MS4448PAE stacked on the same battery?  Does MagnaSine require stacked inverters to be on the same bank or just recommend?  Is their protocol capable of combining different inverters on different banks?  Just thinking around not wanting to get locked into a given bettery (or maybe inverter) tech.  So far it looks a little restrictive to me.

As clarification,  I am talking about what is called "a/c coupling". The new inverters by Midnite should honor all existing in-band  signaling protocols for a/c coupling.  I would like confirmation from Midnite that this will be the case in the new inverter products but have not seen posts from boB or other engineers recently -- is everything OK?

A slightly different concept, stacking of inverters can be accomplished by a/c coupling (in-band) or out-of-band. Magnum for example uses an out-of-band protocol for stacking  implemented by means of  a product  they call "router"  than can stack up to 4 PAE inverters. The Magnum router( "RTR" ) uses ethernet cables to network the stacked inverters together.

While on topic what is the radiation, if any, leaked by the new inverter, has this been tested?

any inverter will have a tad of rf leakage, but even the worst of them couldn't pose a threat in 5000 years.

I also hope for low RFI, but the motivation for me is that I'm a ham.  I still remember the original PVPowered inverters that wiped out the AM broadcast band for a couple of blocks in all directions :)

There are many engineers at MS that are Hams. At least 3+ are involved with the new Inverters. I'll refer to boB as the lead Engineer since he is paid the least...:) His favorite mode is CW...while mobile! Since active hams are actively designing them the RFI/EMI should be very low. If not they all get busted down to Novice!
I got the deluxe kit, it had a solar cell and a meter.

I didn't think there were too many Hams left. Something about younger generations being more interested in Xbox etc.
Have not worked with any Hams but have worked with plenty of Turkeys  ???

One of the many HAMs on here is HalfCrazy (Ryan).

I am as well and neither of us are exactly "kids". Ryan may well be the youngest HAM I know personally. :o

Actually 2 weekends ago I got to sing the general ticket for a 7 year old, that was pretty cool!!

Also MidNite has its own amateur radio club now and most all of the engineers are now licensed. As has been pointed out RFI/EMI has and will always be one of our big concerns and we will do all we can do to make them as quite as possible
