Solar not connected

Just installed my ring solar for doorbell 2 and it says not connect. I had it hardwired and even though it said hardwire as power source, my batteries kept dying in a week. Can someone please tell me what’s the point of have a security system that only sometimes work or can’t step up to monitor my house in fear of battery not lasting. Don’t know what to do. But I know I’m not buying anymore ring items.
