The invention relates to an off-grid micro inverter directly mounted on a photovoltaic module panel. The off-grid micro inverter is directly mounted or attached to the photovoltaic panel. The anode and the cathode of a storage battery are connected with the voltage input port base (3) of the storage battery and are connected with the connection port (4) of the output socket of an alternating-current (AC) load through a cable. The connection port (4) of the output socket of the AC load has functions of AC load connection, carrier communication connection and starting switch connection. The output anode of the photovoltaic module panel is connected with the anode input port base (5) of a photovoltaic module. The output cathode of the photovoltaic module panel is connected with the cathode input port base (6) of the photovoltaic module. Radiating fins are casted on the bottom case (7) of an aluminum shell with the radiating fins so as to speed up heat diffusion favorably. The waterproof cover (8) of the aluminum shell is fastened onto the bottom case (7) of the aluminum shell through waterproof cover fixing screw holes (9). In order to be adapted to the direct inversion power supply of a film type photovoltaic module, a waterproof adhesive the bottom case (7) of the aluminum shell is overturned and attached into the photovoltaic module panel through waterproof adhesives.
Description
technical field [0001] The invention patent relates to the field of "an off-grid micro-inverter directly installed on the photovoltaic module board", especially the installation method and product structure have been changed, and the integration of photovoltaic control charging, sine wave off-grid inverter, and carrier communication has been realized. power supply method.
