Some side-note concerning D.E.A.

*To read this may require you to scroll to the right due to my having written this in un-formatted text (Got lazy).

1.) Although I am old (60ish) and have never once been struck by lightning, nor know of anything remotely close to me being struck by lightning, it has occurred to me that lightning strikes and the risks associated with the isolated happening might be easily mitigated, but am not certain that adding a fuse as close as possible to the solar panels outside and/or adding a ground-loop (to earth) is feasible or profitable. This is an unconcluded area that I need to become familiar with and not be blindsided by the wonders that I see daily with D.E.A. (in fact I would not have been able to take hot showers for the past decade if D.E.A. DIDN'T work, as an example).  Still, even in the course of a 48v D.E.A. what might become of a lightning strike if it should somehow find its way to the hot water tank?

2.) At present there is absolutely no protections added to the D.E.A. applications and the only intermediary devices between the appliance (lights, hot water tank, stoves, etc.) and the source of energy (solar panel) are a quick-disconnect (which is not fused) and a permanently-placed volt meter.  Tentatively, I see no reason to have a fuse or breaker on the inside of the home or building where the appliances are usually located.  What advantage a fuse or breaker at the cut-off switch is not known and I cannot envision many examples as to why it would be necessary, especially if there were fuses or breakers added or already present inline out at the solar panel.  In the case of lightning, would there not be a spider web of energy looking for a ground?

*Also I am not sure what would be the effects of a man-made light, such as those emitted by some weapons. I can tell you this, during lightning storms, my lights instanteously and momentarily turn on during the night-time (or blink in correlation to the duration of the lightning flash).  This can sometimes prove unsettling in an exciting way (whenever it happens it's as if the first time the inside became momentarily and unexpectedly bright).

3.) If the D.E.A. system is examined, we might assess the system as a closed system, however in the case of some sort of energy burst that has never yet been witnessed by me, what would be the effects (and is it worth creating such a disaster just to find out what the result might be?)?


Aside from the thought of a man-made laser or some natural phenomenon such as lightning, I see absolutely no other potentially negative effects from D.E.A. (everything positive for a decade now).  However the 12v D.E.A. is the newest addition to my experiments using D.E.A. and the 12v version is not even two years old so by no means conclusively ....oh who am I kidding, it works flawlessly and I wish I'd done this a decade or two ago.

The only thing about 12v D.E.A.'s and 48v D.E.A.'s is that 48v is much easier whereas 12v devices that have only lights as the dump-load creates a less fault-friendly environment (one little amp too much and it's off to Temu again). 

As for the positive effects, what can I say?  Right now my lights are super-intense and free (without the need for ac, batteries, charge controllers, inverters, etc.) and I enjoy the fact that I don't ever have to turn them off due to worries of some regular expense such as premature replacements or an energy bill predatorially lurking in the mailbox.
