Off-line button solar power generation system

Abstract

The invention relates to the field of off-grid photovoltaic power generation systems, in particular to an off-line button solar power generation system which comprises a solar panel and an energy storage battery, and further comprises a mobile terminal used for registering a user and recharging; a server which performs data interaction with the mobile terminal through a wireless network, and sends a ciphertext to the mobile terminal according to the recharging information of the mobile terminal; a device end which is used for controlling the charging and discharging of the energy storage battery according to the ciphertext received by the mobile end, wherein the device end comprises a controller, and the controller comprises a charging and discharging control circuit which is electrically connected with the solar panel and the energy storage battery and is used for controlling the charging and discharging of the energy storage battery; a main control circuit which comprises a main control chip, is electrically connected with the charging and discharging control circuit and is used for identifying the ciphertext and issuing a control instruction to the charging and discharging control circuit according to the ciphertext; and an input circuit which is electrically connected with the main control chip and is used for inputting the ciphertext. The off-line button solar power generation system has the effect that the selling function of solar power can be achieved on the off-grid photovoltaic power generation system.

Description

technical field [0001] The present application relates to the field of off-grid photovoltaic power generation systems, in particular to an off-grid solar power generation system with buttons. Background technique [0002] The off-grid photovoltaic power generation system is widely used in remote mountainous areas, islands, communication base stations, and areas without electricity. The off-grid photovoltaic power generation system includes a photovoltaic square array. The photovoltaic square array converts solar energy into electrical energy when there is sunlight, and provides power for the load through the solar charge and discharge controller, and charges the battery at the same time; The solar charge and discharge controller is powered by the battery pack for the DC load, and the battery also inverts the DC power into AC power through the inverter to supply power for the AC load.

Problems solved by technology

[0003] In relatively backward countries and regions such as Africa and Southeast Asia, electricity is in short supply and the economy is relatively backward. However, off-grid photovoltaic power generation systems can only be sold in the form of a complete system, and the price and cost are relatively high. The sale of solar power has not yet been realized.
