All, Anyone out there successfully AC-coupled inverters in an off-grid system? Advantages vs. pitfalls?
In my case I'm thinking of its practicality with a Solaredge inverter AC-coupled to an OB Radian inverter. OB firmware makes this pretty easy now. So effectively the Radian is always operating in a grid-backup mode. I already upgraded the system to the Radian, and soon to add 5kw of pole-mounted PV(currently only 1.8kw of 22-year old PV on the roof). This system also just got 16kwh of Blue Ion LFP batteries. This is a last-minute thought I have instead of investing in additional DC charge controllers for the new array. Cost-wise there's not much of a difference between several high-quality charge controllers and a smaller SE inverter w/optimisers.
