description The utility model discloses an improved centralized inversion voltage transformation type photovoltaic power generation monitoring complete device. A centralized monitoring device (4) is connected with a photovoltaic assembly string combiner detection device (1), an inverter control device (2), a transformer measurement and control device (3) and a string inverter (5) via communication lines; a reference string (6) is electrically connected with the string inverter (5); the photovoltaic assembly string combiner detection device (1) is disposed in a combiner box; the inverter control device (2) is disposed in a centralized photovoltaic grid-connected inverter; the transformer measurement and control device (3) is disposed in an isolation transformer; the centralized monitoring device (4) is disposed in the inverter or the isolation transformer; and a synchronizer (8) is connected with the centralized monitoring device (4) and a photovoltaic power station stage monitoring system (7). Efficiency and automation level of a photovoltaic power generation system are improved, and power capacity of the power generation system is increased, thereby facilitating debugging and maintenance.
