The attached diagram is my current setup in my RV with the exception of the boost converter. I am currently dumping the solar panels to to a 36 volt water heater element using the Elecrodacus DSSR 20 and the DEXT 16 . On cloudy days the hot water is not always getting to temp so I would like to augment the dump load. I was thinking I could ad the boost converter to supplement the dump load when needed. My concern is back feeding to the panels. How do I protect the panels and the boost converter. Maybe diodes? The other option might be wrapping the tank in a 12 volt heating pad. Any suggestions greatly appreciated!
