Didn’t know about the trickle charging, neat!

Problem with attaching a load is that if you want to build a standalone unit with the nest, you’ll need some type of inverter when powered off DC, or perhaps a simple sine wave generator? I’m more of a digital, DC power guy.

Yeah, you need a sine inverter, either 24VAC, or 120VAC with a 24VAC transformer.

There might be a way to trick the Nest into running on something closer to DC, but I could only guess.
