A photovoltaic panel encryption method and encryption system in paygo mode

Abstract

The invention provides a photovoltaic panel encryption method and an encryption system in PAYGO mode, belonging to the field of photovoltaic panel encryption. The encryption method of the present invention includes the following steps: the host computer detects the PV voltage of the photovoltaic panel, and sends a verification initiation signal to the encryption board on the photovoltaic panel; after the encryption board receives the verification initiation signal, it processes the verification initiation signal and returns it to the host computer; The board performs two-way encrypted verification; if the verification fails, or the feedback information from the encrypted board is not received within the set time, the host cuts off the input circuit of the photovoltaic panel, and if the authentication passes, the photovoltaic panel is in normal use; Send a verification initiation signal to the encryption board at regular intervals, and perform two-way encryption verification with the encryption board once. The invention has the beneficial effects of: ensuring the safety of the host computer and the photovoltaic panel, and an efficient use environment, eliminating the possibility of danger caused by users using other inferior photovoltaic panels with mismatched power.

Description

technical field [0001] The invention relates to a photovoltaic panel encryption method, in particular to a photovoltaic panel encryption method in PAYGO mode, and also relates to an encryption system for realizing the photovoltaic panel encryption method. Background technique [0002] The new energy industry is developing rapidly under the environment of global advocacy of green and environmental protection. Photovoltaic energy storage power generation is a very important part of it. At present, the status quo of many developing and economically backward countries is that their own power infrastructure is not complete, and daily household electricity consumption cannot be guaranteed. However, with the development of the economy and the improvement of living standards, households' demand for electricity is increasing. However, The price of a complete set of photovoltaic energy storage products is beyond the reach of most households at one time, so the PAYGO (pay as you go) m...

Problems solved by technology

Similarly, it brings great risks to suppliers of photovoltaic energy storage products, because the down payment may not even be able to recover the cost

Photovoltaic panels are accessories of photovoltaic products. They can work independently without the product, which will cause users to use photovoltaic panels to supply power without renewal fees.
