Off-grid Solar with DC Backup

Off-grid Solar with DC Backup

I would like advice on a potential new set up I am looking at installing in my home.
I have a small water heating system that runs @ 150w 24v DC, I intend to use the solar to power the heating system in the day (or sunny) but at night would like a standard AC/DC psu to power the heating so essentially a constant feed one way another with the solar taking priority when it can.
1) How would I achieve this?
2) Could I use a standard solar regulator and plug the AC/DC psu into the battery terminals?
