So to better explain what Im after, I have a 12v solar panel circuit. So the panel, controller, battery and light.
I wanted to expand this lighting system, but expect on cloudier days, the battery wont get the necessary charge. So I was wondering how Id go about getting a sensor to pick up the voltage dropping past a certain point and then I will have either a backup charger (that I guess could preferably turn off at a certain voltage as well) turn on to charge the battery up or the power source is changed from the battery to direct from the 240-12v transformer.
Or any suggestions would also be appreciated.
Thanks
