Has anyone tried 12 volt water heater elements, they crew right into your tank, and are sometimes used to dump wind or solar PV overload.
Should be able to hook directly to a 12V PV collector of any size, the bigger the better. With a small collector no control unit should be required.
If your heater has 2 elements use one and supplement with the 110 whenyou need it, otherwise shut the 110. The elements start at 40 bucks online.
