Abstract
A photovoltaic controller comprises a solar cell panel, a storage battery and a load which are connected in sequence. The solar cell panel and the storage battery are connected through an on-off device Q1, and the storage battery and the load are connected through an on-off device Q2. The photovoltaic controller also comprises a control unit for controlling on-off of the on-off devices Q1 and Q2. The control unit comprises a voltage detection circuit, an MCU and a driving circuit which are connected with the storage battery in sequence. Two output ends of the driving circuit are connected with the on-off device Q1 and the on-off device Q2 respectively. The photovoltaic controller is simple in structure, easy to manufacture, stable in performance and precise in control, and has an overcharge and overdischarge protection function.
