That is not one such system, that is THE go to system for trying to keep an "old school" string installation. Plenty of drawbacks to that systems.
SMA's version has been an unmitigated disaster. Years to release, and many reports of it randomly shutting down and requiring a reset on the roof.
Keep in mind the system needs to be listed for the purpose, so options are VERY limited.
The next phase looks to be string inverters that broadcast a trip signal over the DC powerline to Tigo devices via a standard protocal (Sunspec). Tigo might be a more simple devices, but is still electronics on the roof.
I'd want a system that is somehow capable of providing me array power when the grid is down.
