Will this work with 12V dc supply??

It is a DC powered device, yes, but we wouldn’t advise it with any power source besides what it was designed for. The current and voltage requirements to actuate the solenoid are likely much greater than what a solar panel would provide. If you have further questions, though, please don't hesitate to contact our Support team at 1-800-488-6156. We'd be happy to help in any way we can. Thanks!
