Solar photovoltaic inverter

Abstract

The invention relates to the technical field of photovoltaic power-generating inversion, in particular to a solar photovoltaic inverter. The solar photovoltaic inverter comprises an inverter device installed in a circuit board, input terminals, output terminals and safety protection switch devices, wherein the inverter device has a DC power supply input end; the DC power supply input end receivespower supply output of a DC power supply and an AC power supply used by a plurality of photovoltaic cell panels, and provides AC power adjustment for the AC power supply; the input terminals and the output terminals are electrically connected with the photovoltaic inverter respectively; each safety protection switch device comprises a plurality of protection switches which are connected in parallel, and each input terminal corresponds to one of the protection switches; and the input terminals are electrically connected with the photovoltaic inverter by means of the safety protection switch devices. The solar photovoltaic inverter has the function of AC power adjustment for the AC power supply, can prevent the occurrence of safety accidents such as electric shock, and improves the safety ofthe photovoltaic inverter.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation inverter, in particular to a solar photovoltaic inverter. Background technique [0002] A photovoltaic inverter is a power conversion device that converts direct current generated by solar panels into alternating current. Ordinary photovoltaic inverters need to be controlled manually, which is inconvenient, and there is a lot of room for improvement in the power interactive control link. The present invention is a kind of solar photovoltaic inverter, which uses improved technology to manufacture the photovoltaic PV module of the power adjustment unit inverter. The principle of this technology is simple, and its design scheme is reasonable and practical. Thus bringing about new technological changes. [0003] At the same time, it is located outside the control box of the photovoltaic inverter, which is convenient for wiring, but it is likely to make people mistakenly think t...
