Abstract
The utility model provides a photovoltaic control device with a self-heating function. The photovoltaic control device comprises a photovoltaic component, a micro-inverter, an island detector and a link relay. The island detector is connected between the link relay and the power grid; the output of the photovoltaic component is connected with the input of the micro-inverter; and the output of the micro-inverter is connected with the link relay. In the actual installation of the photovoltaic control device, a plurality of inverter modules are connected together in series and are inserted into the power grid; each inverter module is not required to load one island detector; only the inverter which is most close to the power grid is loaded with the island detector; meanwhile, one link relay is additionally arranged in the inverter; and the power grid and the next inverter can be cut off. When the power grid is cut off, the inverter detects the island effect to cut off the grid-connected relay and the link relay, thereby increasing the actual electric energy production and reducing the interference of the power grid.
