Can Charge Controller Work Without Solar Panel?

[inetdog]

Hi, I am new in this forum and I have just bought some items to make a small home solar lighting system. I have a charge controller, a battery and an LED light. I have ordered a 40W solar panel but yet to arrive so I decided to test the charge controller.

I off the timer and light sensor available in the charge controller itself according to the user manual given. I then connect the battery and LED light to the charge controller. I presumed if the sensor and timer are off, the LED light should work even in the day time. But I got no light!

Note, the LED light and battery worked perfectly without the solar charge controller.

Please help!

What maker and model is the CC? Is it actually a solar lighting controller rather than just a simple CC? It sounds like it.
Most of those will sense the current from the panel itself as an indication that it is daytime and will inhibit the Lighting Load output because of that.
If your manual says that you can disable that feature, double check your work.
