What is more “cost effective” in your opinion?Arguably the wrong tool for the job ( offgrid ) and less cost effective if actually cobbled together to function ( AC Coupling ).
Depends on the NEC code designing too.What is more “cost effective” in your opinion?
And shading if you want to use optimizers adds cost. Cabling/wiring can be cheaper with micro inverters.Depends on the NEC code designing too.
By far, string inverters are the lowest cost per watt, so if one is NEC2017 or older ( no module level requirements ).
Once you are in NEC2020, its module level required shutdown, then the math is different as something has to be there, but even in this case its $30 rss only module vs $165+ for micro inverters, so more than 10 panels, string configuration still wins.
Most hybrid inverters have ample capacity for most systems ( like most things nothing is one size fits all ), so just adding panels with RSS is the best option.
This.Or if you have maxed out the DC side of a hybrid AIO.
If you are connecting it to an AC coupling capable system.You can easily use microinverters to supplement an off-grid system.
I have a cheap 300W gti plugged into mine. Just wanted to see if it works. Also means I'm running AC thru 30m of cable instead of DC. Less voltage drop and simplifies the wiring.

I’m paying less than $100/panel to add micros. That would work out to be ~$167 if I instead added another Sol-Ark 15K and that’s before RSD/Optimizers or figuring more cabling into the equation.
I looked around at his videos. Great resource. But I don’t see a vid one off-grid micros. Could you link? ThanksYou can easily use microinverters to supplement an off-grid system.

They are not "off grid" micro inverters.I looked around at his videos. Great resource. But I don’t see a vid one off-grid micros. Could you link? Thanks
Micro inverters are designed for grid-tied.What does it means "AC Coupling" exactly and what solution are exits?
And why does Micro-Inverter forcing AC coupling?
