An inversion process is carried out before photovoltaic grid connection; before the direct-current heat pump unit is used, an inversion process is also carried out, and loss can be caused by inversion. The inversion of the two is opposite, so that a device is developed, direct current generated by photovoltaic can be directly preferentially supplied to a direct current heat pump unit for use, insufficient electric energy of the direct current heat pump unit is supplemented by inversion of a power grid, and the electric quantity of inversion is reduced, so that the loss is reduced, and the efficiency is improved.
