Solar energy controller and realizing method thereof

Abstract

The invention discloses a realizing method of a solar energy controller, and aims to provide a solar energy control method for adjusting the output power according to the electric energy production and accumulator capacity on the same day so as to ensure that lights are switched on every night all the year. The realizing method comprises the steps of setting brightness level output functions of different levels at constant output according to different variable values of power generation of the accumulator and capacity of the accumulator; detecting the variable values of power generation of the accumulator and capacity of the accumulator constantly to obtain the variable values of power generation and capacity of the accumulator and store the variable values of power generation and the capacity of the accumulator and performing logic operation of the variable values of power generation and the capacity of the accumulator; judging whether logic operation result meets the requirement or not, and transferring the brightness level output functions according to the variable values of power generation and the capacity of the accumulator when the requirement is met, and outputting constant current of corresponding level according to the brightness level output functions by the accumulator to drive the LED. The invention can be applied to the field of solar energy street lamps for solar energy generation.

Description

technical field [0001] The invention relates to solar charge and discharge control processing technology, in particular to a solar controller with adjustable discharge and a realization method thereof. Background technique [0002] Existing solar controllers generally have low efficiency and lack reasonable protection for battery charge and discharge, which shortens the life of the battery and makes the system unstable. Parallel protection is used for battery overcharge protection, which is easy to burn the protection tube; the maximum power tracking of the photovoltaic power generation system is MPPT ( Maximum Power Point Tracking, maximum power point tracking) There are many methods, such as admittance increment, fuzzy control, disturbance observation, etc., which are relatively complicated to implement and cost relatively high. Because LED has high efficiency, low energy consumption, good light quality, long service life, safe use, and environmental protection, it is the ...
