I have utility approval for a plug-in solar setup and am comparing options for four panels, with AC output limited to about 1,200W. I’d also like some room to oversize the panels, but I’m not sure which microinverters are dependable or a good fit.
What microinverter would work for a 1,200W plug-in setup?

One option to investigate is an APsystems unit in the 900VA range. That is below your stated 1,200W ceiling, so check whether it actually meets your output target before buying. With four panels, match each panel to the inverter’s input voltage and current limits, and check how much DC capacity it allows. The AC rating alone doesn’t tell you whether the panel combination is compatible.

If export control matters, the NEP BDM-1200LV has been suggested with a BDNZ-WiFi-2 meter for limiting backfeed. Confirm the exact model and setup with the manufacturer and your utility, since a bidirectional utility meter that credits exports is not the same thing as an export-limiting device. Also check whether this equipment is available where you live.

I’d start with the utility’s approved-equipment requirements, then ask them to confirm the exact inverter model and grid profile they accept. A familiar microinverter brand isn’t automatically approved for a receptacle-connected setup, and local installation rules can still apply. Also, grid-tied inverters generally shut down when the grid is out, so this won’t provide backup power by itself.
