Hmmm I got to figure out something, how to build a voltage controlled switch the usual voltage output of my solar panels is around 17-18.5 but under low light conditions "evening/ morning" it falls below 16V now I will be using an lm317T to create a stablized 16V because the cells I'm charging can safely handle 16V, but no more. the catch is that while the LM317T can handle voltages of 16.3 and still create a stable 16V output it cannot handle any lower than that I think. so my problem is I need to ensure that this circuit turns the power off when off when the source "my solar panels" go below 16.3V. BTW do you think that 16.3 V is a safe voltage for an LM317T on a 16V output?
