question, I know: what has worked well as a 24V – 12V DC-DC step-down
converter for a Sun Frost? I am doing a design to completely rebuild/replace
an early-90s off-grid 12V system with a new system at 24V. The only DC load is
a Sun Frost. I think it’s an RF16, so dual-compressor. I know of at least
three converters: Solar Converters; BZ Products; ICT; and I’m sure there are
many more. What has worked well, with minimal ghost load?
