Pretty interesting product, and while not technically new, they seemed to have worked out some of the kinks over the years.
It is a DC powered mini split system that is connected directly to solar panels and runs for "free", obviously only during the day.
Seems they are targeting to augment a typical house air conditioner system, though they do have the ability to connect to AC so the system can run when the sun is down or cloudy. Only available in 12k or 18k btu so wouldn't be enough for a typical sized home. Could be interesting for tiny home's that are not grid-tied already.
Anyways, thought some of you guys might be interested in learning more. No affiliation.
