Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] Such as Figure 1-2 A movable cabinet-type photovoltaic water pump that realizes distributed MPPT is shown, including photovoltaic components arranged on the surface of the electrical cabinet and electrical components arranged inside the electrical cabinet;
[0025] The photovoltaic assembly includes a photovoltaic panel 1 surrounding the outer periphery of the cabinet body 13 and a photovoltaic panel 1 arranged on the top of the cabinet body 13;
[0026] The electrical components include a DC / DC control circuit 2 that is connected to each photovoltaic panel 1 and can realize maximum power tracking. The output ends of each DC / DC control circuit 2 are connected in series to form a DC bus and connected to the pump control unit. The output end of each of the DC / DC control circuits 2 is also connected to a bidirectional isolated h...
