Abstract
The disclosure provides a photovoltaic electric appliance system and a voltage protection value control method and apparatus thereof, and a controller. The photovoltaic electric appliance system includes: a photovoltaic power generation module, an electric appliance, and a grid-connection module. Said control method comprises-: acquiring the working states of the photovoltaic power generation module, the electric appliance and the grid-connection module; and according to the working states of each, determining an operation mode of the photovoltaic electric appliance system, and setting a voltage protection range of the photovoltaic electric appliance system according to the operation mode. By determining whether the grid-connection module is working, whether the electric appliance is working, and whether the photovoltaic power generation module is working, and by setting voltage protection values respectively for different working modes, the invention achieves the effect of compatibility of protection values and improves the system performance.
