Description
technical field [0001] The invention relates to the fields of safety, charging control, and automatic load dimming control of storage battery equipment, specifically a combination of functional modules of a wind-solar hybrid controller for battery flow monitoring, charging control, and load automatic dimming, which is suitable for various wind-solar hybrid controls Device. Utilize wind energy and the sun for electric energy and energy storage conversion. Wind-solar hybrid controllers are widely used in street lighting, urban street lighting, highway street lighting, marine farming lighting, home lighting, etc. Background technique [0002] There are some problems in the actual application of wind-solar hybrid systems in China. The climate difference between the north and the south is large, and the application environment of wind-solar hybrid systems is partially limited. For example, wind-solar hybrid systems on urban roads are blocked by tall buildings, bridges, and trees,...
