I don't have a definitive answer. The Radian does have relays but since it's heritage is Off Grid I don't think the Radian has the functionality that a true grid interactive inverter like the Skybox has. Clearly it can island to protect Linemen.Someone mentioned there is no ATS in the Radian, but I thought it could consume grid power when PV/Battery is not enough. Anyone know that answer?
My first Inverter was a Radian seven years ago before it had AC coupling and I just used it as a crude load shifting device using some batteries from an EV conversion project. I sold it when bought another home and bought a Skybox when it first came out. By then (2018) I was more informed about where NEM policies, rates and TOU periods were heading and knew I wanted a true grid interactive inverter.
My only caution about the Skybox is that with the new Mohawk, I don't know what it's future is? Certainly Outback will support it and continue firmware updates. It continues to work for me with my DIY battery pack. The Mohawk offers a NEC 2020 compliant battery system that is integrated with communication between the two. The cost is significantly higher than a Skybox with DIY batteries.
