I have built one of Tony's Solar Hot Water pcb's, but only up to testing stage, the HI/LO switching (using trim pots) on the 555, is working with some playing around, but found the Gate driver IC is not switching, I was planing to change its power supply from the 11.9v to around 15v and try again. Thanks for posting and explaining your setup. I could not get the one Tony built me to work either and couldn't figure it out. Let me know how you go with yours as I really would like to be able to use this but I am sadly lacking in knowledge to know how.
