  • Page 78 Remark: [1] Solar panel active: PV voltage r47.50 is greater than the threshold setting P47.56 for switching to hybrid power supply. [2], [6] The driver works in photovoltaic independent power supply mode/hybrid mode: it can be checked through function code r47.58. [3] The output frequency is too low and has been maintained for a period of time: the operating frequency r27.00 is less than the weak light detection threshold P47.05, and the duration exceeds the weak light detection time P47.06.
  • Page 79 [5] The sleep time is reached: the bus voltage r27.03 is greater than the weak light wake-up voltage P47.45, and the sleep time exceeds the weak light wake-up time r47.07. [7] The photovoltaic voltage is high enough and has been maintained for a period of time: the photovoltaic voltage r47.50 is greater than the switching to photovoltaic independent power supply threshold setting P47.55, and the duration exceeds the weak light wake-up time r47.07.
