Embodiment Construction
[0014] The invention will be described in detail below in conjunction with specific embodiments.
[0015] This embodiment combines figure 2 The illustrated photovoltaic off-grid inverter is used for illustration, and the commercial power described in this embodiment is a three-phase commercial power.
[0016] In this embodiment, in order to give priority to solar power, the operating voltage point of the photovoltaic output control module is set to 430V, and the operating voltage point of the mains rectifier module is set to 405V. The control method of the photovoltaic off-grid inverter in this embodiment mainly includes two steps:
[0017] First, check whether the solar energy is sufficient. Specifically, the voltage of the bus a is detected. Under different levels of solar energy, the voltage provided by the photovoltaic output control module to the bus a is different, so that the voltage of the bus a can be used to determine whether the solar energy is sufficient. Set a...
