This is in reference to my solar light controller here
http://forum.allaboutcircuits.com/showthread.php?t=77021
I have the ability to shut off the light once the battery level reaches a voltage that is selectable.
I am currently shutting the light off when the battery reaches 12V. But of course when I remove the load of the battery the level rises above 12V. But the design of the controller keeps the light off as it should. The process is reset once charging starts.
The other night I noticed that the light was off so I checked on it. It shutdown at 11.8V (the lcd shows the shutoff voltage) but the battery voltage was 12.1V (because there was no load).
I understand that lead acid batteries should bot go below 12V? If so, is that loaded or unloaded? In other words could I safely set my level to say 11.5V?
