Something I'm considering seriously given the potential for energy reduction.
A feedback comment from a customer on one of the supplier sites mentioned that he'd been able to use these 12v units connected to a car battery in a stable without any electricity supply.
This got me thinking. Considering the frequency of power cuts where I live, might it be a good idea to introduce a backup battery into the circuit, with overcharge protection naturally?
What I don't know is whether this would be in violation of any safety standards, or even if there are any standards for this new technology.
