Problem constructing a solar powered waterfall, please help?
Hello, I have constructed a waterfall in my garden. It consists of a small dc pump which consumes 0.35a at 12v and a bigger pump which consumes 0.87a at 12v and a 5050smd led strip encased in a tube to make it waterproof, which consumes 3.7a at 12v totally 4.9a at 12v. I have a solar panel with 12v 30w and a solar charge controller with 12v 6 a capacity and a sla battery 2v 7ah capacity. I calculated a runtime of 1.4 hours when all three devices are connected together. But they last for only 30 seconds and then the charge controlled shuts them down with low battery indicator. I don't know what went wrong, can someone please help?
