Description

technical field [0001] The invention relates to the technical field of solar controllers, in particular to a novel MPPT solar controller. Background technique [0002] In the prior art, the constant voltage tracking method CVT or the disturbance observation method is usually used to realize that the output voltage of the holding solar controller works near the maximum power point. [0003] When the constant voltage tracking method CVT does not consider the influence of temperature, the volt-watt characteristic of the photovoltaic cell is a parabola, and the maximum power point is almost on both sides of the same vertical line, which makes it possible to approximate the trajectory of the maximum power point As a vertical line of a certain voltage, if a controller is added between the battery and the load to keep the output voltage constant at this voltage value, the battery basically works near the maximum power point. This method is called constant voltage Track Act CVT. ...
