OK thanks that is more understandable I think so the 317HV can accept a higher input voltage and feed 9 Volts to the circuit .The Solar panel then feeds through a MOSFET to the battery with a blocking diode ?.
Yes, the 317HV can take 60 volts max from input to output. I figured maximum battery voltage of about 58.4. So there should be 10 volt safety margin.
Pin3 goes high and turns the transistor 2n7002 on which turns the MOSFET on . Is that how it goes? or is the 3 pin going low that activates the rest ?
Pin 3 going high turns it all on as it was before.
The 555 can take up to 15V input voltage so maybe I could adjust that to !5V
The solar panel is putting out 80Volts !
You could. Or maybe 10 volts would be an easy number to work with.
I missed the open circuit voltage of 80 volts on the panel. You will need to change the 7002 to a 100 volt FET-say an FQU13N10LTU.
[quote[I have not used LTSpice for years but it seems that you have it set to 44V? or is that 60?
