I settled on a Zoeller Spin 508 combo sump with dc backup system. Found it in stock at a local plumbing supply (did not offer to them that I was not a plumber, nor did I have an account)

Decided on a Fleet standard size 31 AGM battery that was available at Oreillys locally instead of buying the over priced Aquanot branded AGM

Installed, setup, and was very happy with the result, house safely out of risk from sump failure
