The question is: Will you be getting rid of your existing inverter and replacing it with a single hybrid inverter (known as DC-coupled. . Why it matters: These details determine whether you add storage through AC-coupling (most retrofits) or DC-coupling (which needs a compatible hybrid inverter), and whether upgrading to microinverters makes sense now or later. But even if your system wasn't designed with storage in mind, you still have options. [pdf]
