Description

technical field [0001] The patent of the invention belongs to the technical field of solar photovoltaic power generation, and in particular relates to a portable online fault diagnostic device for photovoltaic off-grid power stations. Background technique [0002] Photovoltaic off-grid power station is a photovoltaic power generation system that operates independently. It does not have any interface with the public grid and belongs to a power generation system integrating generation, storage and supply. Its basic working principle is that the photovoltaic module generates electric energy under the sunlight, and the electric energy is supplied to the load through the off-grid controller, and the excess electric energy is stored in the battery. When the light is insufficient or at night, the electric energy in the battery passes through the off-grid controller. Continue to supply power to the load. Photovoltaic off-grid power stations are small in scale and suitable for distr...
