You are probably right. But this is a theoretical question as well as a practical one. I really want to know what would happen doing it the way I proposed and why.

Good ol' Battery U seems a bit dated. I have read some of their stuff but it is 'past era' stuff. They have solar panels at $5.00 a watt and that sort of thing. Doesn't make him wrong, of course, but it also seems NOT to be current. And, sadly, there is no reference to combining charger...

Thanks, Don. No, I hadn't seen it and it will provide me with a lot of info. Appreciated. Mind you, I have come to know that everyone has at least two opinions on the nature of batteries but, as I have about wtenty, this might help narrow it down a bit. But what about the PWM up the back...

An ultracapacitor is, it seems, just a HUGE, more efficient capacitor acting as a battery. MIT is developing them. Which is good. For maybe, Ford Motor Company. But, for those of us living in the forest and 'making do', it is not an option. We Luddites have to use lead acid. Rich Luddites...

My capabilities are pretty limited but if there are capacitors for this, I can do it. IF I KNEW what an ultra capacitor spec for this was. But back to the main question...why does this bode poorly for the batteries? Why would the PWM going in one way and the MPPT going in the other make any...

The original question was really two questions - how can I use my Tec cable for all of what I wanted to do. I was going to run three circuits using the three wires in my cable and use the ground as a common neutral. But then I found some more cable so I have decided to give dedicated wires to...

More than that, B, if you read the codes as well as the How-to books, it is all easier to understand. And we needed 'easy'. Both of us are pretty stupid. How stupid? Well, I used to race motocross when I was young...just for starters (seeing your avatar) ;) No problem with wasting anyone's...

Electrical background: Zip. Nada. Zilch. Used How-to books to wire my house. Used how to guides to wire up original solar array and OUTBACK system. Outback is 48v. Original system was 640 watts. Keeping that system. New system is also 48 volts (by label) but made from different panels...

I have a three circuit solar array. Live off the grid. Each is 48 volt rated but two are really 90 volt rated (3 x 250 watt x 24 volt which are really 30 volt). The other is more like 60 volt. (2 strings of 4 80 watt panels x 12 volt -really 17.5 volt - total 640 watts. I have three +...
