Hi All,
Watching JB's video has my head spinning (again) . . .
A few observations (you guys probably pounced on all of what follows,
and then some, but what the heck . . . ):
1) Notice the 17+ (almost 18 volts from the "Solar Panel" as supplied to the battery pack - 18 volts is mentioned in a 12/22/2009 JB post/sketch);
2) Looks like the modified TSw is about half of what I'm fighting on my 2X2 battery setup - ergo fewer drops, so the 18 volts above;
3) Maybe there is some kind of "load" internal to JB's unit, or he has maybe
16V or so slamming the battery bank - the reason for the uncertainty is the 10 Amps+ registering most of the time on the meter;
4) At 10 Amps that might push the heck out of what I'm using as to SOA - suggests some really beefy hockey pucks at work;
5) Pulses look like 2Hz or so - not sure about on time vs off time but my guess is fairly symmetrical;
6) Have a weird "hunch" that the "switch" is in the neutral line running from the battery bank (-) over to the "Solar Panel" (-) - maybe this hunch is based on the early-on 3Bat switch John B posted - just speculation here.
Caveat: This is NOT to second guess what John B showed. It is posted to stimulate review of a LOT of material recently posted in which there were a lot of good suggestions (and JB dropped a lot of hints). Again, like the SG motors, maybe the wild card for each of us is the batteries we're each fighting with and trying to tune around.
Okay . . . back to frying more components - the lab is colder than a witch's broomstick . . .
Best,

JB is never connecting the negatives of the batteries to the negative of the solar panel. He is using the negatives just like in the scalar charger or 4 battery TS. The positives may be connected, but I don't think that is true either, I think the positive of the battery is connected to the positive of one of the capacitors through a tranny or diodes.
I believe he is filling two caps, then putting them in serial and sending that to the batteries. While he is applying that potential to the batteries, he is filling the other two capacitors. Notice the current on the generator, it is varying between 3 amps and .5 amps, meaning, the caps are filling up from 6.X (serial 12.X volts after discharge to parallel 12.X / 2) volts to 17.6 volts. Then he switches cap banks, and does it all again. Pulsing the potential into the batteries in a way that they like it. (He may not be switching cap banks either, just using two caps in parallel X 2, and filling them up and sending it to the batteries)
It is a very simple operation, is my guess, but when you can see either the scalar charger or the 4 battery in operation it seems even easier.
It looked like 1/2 hz or 1Hz to me, but it is somewhere between 1/2 to 2Hz would be my guess.
You can only see 5 devices (switching neg of solar panel to each bank, swithing from parallel to series on the caps = 4, but don't know what the other is for), but you can see some optos on the board too. What is behind the big heat sink is anyone's guess, but probably some devices to send in the 10+ amps to the batteries.
Wonderful stuff.

P.S. If this also is working in low light conditions, then all my comments could just be hogwash.
that's me, whistling Dixie. 
. It would explain those "beefy" devices on the heat sink.... being paralleled IRFB or similar, driven by SG, H11D1, MJL's, perhaps? SG circuit is little different than one I'm working on. I posted this patent idea few months ago in Solid State thread, while I was working on Solid State and Radiant Charger but no one commented back then. Amazing stuff and pleasure to watch. A bit frustrating to work on
