This circuit when used like this with solar panels should be self regulating. When a 6 v zener is used the battery should not charge past 14-15v, when the battery voltage gets to 14-15v the panels will no longer be able to raise the cap voltage enough to dump and the solar output will be blocked by the closed SCR so only the oscillator output will continue to charge the battery.
And if and when the voltage of the battery drops the caps will resume pulsing.
If the zener is jumpered out, theoretically the circuit could charge the battery to 19- 20 volts or so, it is good to equalise the battery bank by charging to 15.3 volts every now and then and this circuit allows that under supervision without the need for an expensive charge controller. There really needs to be a way to stop overcharging when not using the zener. I havn't worked that out yet.
I have learned so much stuff here I only hope to contribute a part to help, I don't really deserve much credit as most of what I have learned I have learned from others too numerous to name. The stuff I have learned here is becoming very usefull to me.
Word is spreading of these things, I have a few people around here (off grid) who are open to the possibilities. Though they are busy people and for now I offer to try to fix thier batteries for return work from them. Work that I can no longer do because of my neck problem. And no money changes hands.

Updated schematic here. I added 3 pole switch for zener selection, a pot on the oscillator trigger and changed the fixed base resistor to 1k, also added a neon.

I'll post my latest update to this circuit here but i'll make a new thread soon when I have time. New drawing has switch and SCR+Caps arrangement to charge the oscillator source battery ( I use a cheapo charge controller there), I have adjusted the zener value's ( they need to be selected for the particular setup "tuned" ) i've also added an led to indicate the voltage difference is working which I havn't tried yet. I can probably think of more things to make it more complicated.

I just realised the setup now has three SCR's.
