Solar energy electricity generation recharge/discharge intelligent controller

The utility model relates to a solar energy electricity generation recharge/discharge intelligent controller, which comprises a charge circuit, a charge sampling circuit, a discharge sampling circuit, a battery terminal voltage sampling circuit, a microprocessor, a relay execution circuit and a load control circuit, wherein, the charge circuit is provided with a direct charge closed circuit and a constant voltage floating charge closed circuit. By that the magnitude detection of charge current and the state of a battery, the appropriate charge modes can be automatically judged and selected: when the charge current is big, direct charge can be adopted; when the charge current is small or battery terminal voltage reaches a predetermined value, floating charge can be adopted. The utility model both enhances charge efficiency and solves the heat dissipation problem of an antireflection diode.
