String Inverters
Simply put, a string inverter is a device for converting DC to AC power and which is designed for high voltage DC inputs. Using a string inverter, the solar panel array, still typically rated at 12V, 24V or 48V each panel is wired in series, rather than in parallel. It’s that simple: The panels are arrayed in a “string” to produce the same amount of total power but at higher voltages (typically 200-800V), thus lower current, allowing much smaller wiring and much smaller and lighter weight inverter construction.
