Hello every one,
Thanks for your ideas,
yes you are right
my idea is when solar energy get fail in evening a circuit should start using supply from DC adopter and in morning again turn solar power on.
and i want to have this circuit before my charge controller. circuit will be supplying...
no, i have a charge controller. I need a circuit which can switch the inputs power source to my charge controller form solar to adopter in evening and to solar again in morning, i need to reduce my backup system(batteries) as it is very costly.
thanks
Hello,
Thanks for your reply.
i have solar panel of 200W ,28v and 7 amp (optimum operating) which is running: i am using charge controller of 12 v and 20 amp
3 12volts DC fans= 3x26watts = 78 Watts
5 12volts DC lights= 5x7watts = 35 Watts
Total = 135...
hello,
I have two DC power sources primary and secondary, i need circuit which should simply turn my primary power off when it gets lowere than some given voltage and turn on secondary power, and again turn on primary when it gets higher than same given voltage.
same type of circuit is...
