DC -> DC -> DC Solar. With a single used solar panel, a few used batteries, and $40 in parts you can power your life, transportation and all. Add an ESP32 Arduino to a 95% efficient DC-DC buck converter controlled over serial and you get an internet-connected, privately hosted smart solar MPPT power system.
Using a Drok DKP6012 converting 10V-75V down to 0-60V at 12A/720W works well as a nice cheap fully functional system for a house solar panel to 48V battery.
I'd like suggestions for a cheap programable buck converter to swap out the Drok DKP6012 to feed a house panel into 12V at about 20A. I'm thinking a WZ5020L DC DC Buck Converter might be suitable.
