For achieving the above object and other relevant purposes, this utility model provides a kind of photovoltaic DC-to-AC converter body structure, it circuit board container including a metal material and the rosette of a plastic material, described circuit board container is fixing with described rosette to be connected, and is provided with through wires hole between described circuit board container and described rosette.
Preferably, described circuit board container setting several draw-in groove, described rosette is provided with several grab, described draw-in groove and described grab position one_to_one corresponding, and described grab is stuck in described draw-in groove.
Preferably, the edge of described rosette is connected by screw with the edge of described circuit board container.
Preferably, it is provided with dividing plate in described rosette.
Preferably, described circuit board container is provided with radiating fin.
As mentioned above, photovoltaic DC-to-AC converter body structure of the present utility model has the advantages that casing is divided into circuit board container and rosette two parts by this photovoltaic DC-to-AC converter body structure, rosette uses plastic material, thus can effectively reduce the cost of photovoltaic DC-to-AC converter casing, rosette is attached by the way of clamping with circuit board container simultaneously, attachment structure is simple, have only to a screw and just can both are securely attached to together, the efficiency that both assemble can be effectively improved, and use this structure also can alleviate the weight of casing to a certain extent, casing is made to install, hang.
