Larry, I recommend considering retrofitting the SolarEdge “StorEdge” Li-ion battery. It’s a high-voltage battery on the PV side of the inverter. We have a few out there now for a few months without a problem. Really like the design concept of the storage on the PV side, increasing system efficiency.
We’ve done quite a few AC-coupled systems, which Outback FX, Outback Radian, and SMA Sunny Island/Sunny Boy. The Outbacks require a cutout relay. We won’t do Radian AC-coupling any more, as the setup, documentation, and support is a royal PITA, and have had failures in the “ROCB” automatic cutout breaker. Even when the ROCB doesn’t fail, it often cuts out when it isn’t supposed to, like at the start/end of a float cycle. My understanding is that Outback doesn’t support AC-coupling any more with the Radian. Kelly Keilwitz, P.E.
