Controller, power inverter, photovoltaic power supply system, and method for controlling deactivation of at least one photovoltaic module

摘要

A controller (114) for photovoltaic power supply may be configured to be connected with one or more photovoltaic modules (102) and configured to be connected with an AC grid terminal (108) for grid power supply additional to the photovoltaic power supply. The controller (114) may be configured to monitor the status of the AC power at the AC grid terminal (108) and to generate a signal for deactivation of the photovoltaic modules (102) if the AC power is off.
