[RE-wrenches] off-grid AC coupling feasibility

[Kirk Herander]

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. Thanks.
