Abstract

The invention discloses a solar controller circuit which comprises a main battery, a standby battery, a circuit switching module, an MCU and a voltage dividing module. The anode of the main battery is connected with the first end of the voltage dividing module, the second end of the voltage dividing module is connected with the input end I1 of the MCU, the first end of the circuit switching module is connected with the anode of the main battery or the anode of the standby battery, the second end of the circuit switching module is connected with the first output end O1 of the MCU, and the cathode of the main battery and the cathode of the standby battery are connected with the second output end O2 of the MCU. When the voltage dividing module detects that the voltage of the main battery is lower than or equivalent to a preset voltage threshold, the MCU transmits a switching control signal to the switching control module, the circuit switching module receives the switching control signal, and the first end, which is connected to the anode of the main battery, of the circuit switching module is connected to the anode of the standby battery. The solar controller circuit is conducive to reducing the static loss and improves the safety level.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a solar controller circuit. Background technique [0002] The solar charge and discharge controller (hereinafter referred to as the solar controller) is an automatic control device used to control the charging of the storage battery by the multi-channel solar cell square array and the power supply of the storage battery to the solar inverter load in the solar power generation system. It is widely used in remote rural areas and areas where electricity is inconvenient. However, in case of continuous rainy weather, the battery cannot be charged by the sun for a long time. Even if the load is not discharged, due to the loss of the controller itself, if If measures are not taken in time, the battery will be damaged after a long time. Contents of the invention [0003] The invention discloses a solar controller power supply circuit in order to reduce the static loss of t...
