Does anyone know if you could buy 48V DC powered heat pumps in New Zealand or Australia?

technically yes, because you can get peltier cooling units that are a form of solid-state heat pump, but their COP is less than 1.
What do you actually want to do with it? What heating/cooling power do you want?

I know that there’s 74vdc units available for locomotives and I a google search shows 48vdc units available.
Probably not quite as efficient but a 48-230vac inverter.

Thanks for the replies guys. It is for a research project. I've seen them on google mostly from US suppliers, but didn't find anyone selling them in NZ.
