This is my first DIY solar project: Nermak model 12V12A LiFePo4 battery and Renogy 12/24V 10A PWM solar charge controller. It's going to replace a Bluetti EB3A for charging HT radios, running LED lights, and powering an HF radio.
I'd planned to charge it with a 12V/10W solar panel and cigarette lighter car charger. The solar panel works ok when it gets above about 18 volts, which requires almost full sunlight. The car charger, at 14.4 volts, doesn't put any power through the charge controller. So reading here and other places I find that's the way it's supposed to work: I need about 5 volts more than battery voltage going into the controller.

Will this 12V to 24V step up converter charge my system with around 14 volts input, without harming my charge controller? Would there be a danger of it putting out too much power with the solar panel in full sunlight?
Or is there a better solution that I haven't found yet?
