Specifically, when sunlight irradiates the silicon solar cell module, a direct current is generated on the silicon solar cell module through the J1-1 normally closed contact and the resistor R1, and then the light emitting diode LED1 connected to the resistor R1 is energized, and it starts to emit light, i.e., the battery B is ready to start charging. At this time, the switch K1 is closed, and the controller U3 outputs a voltage, so that the subsequent circuits start to operate. The controller U1 is used for comparing whether the battery B has the over-charge condition, and the controller U2 is used for comparing whether the battery B has the over-discharge condition, so that the normal operation of the battery B is ensured, and the service life of the battery B is prolonged.

When the terminal voltage of the storage battery B is smaller than the preset voltage value of excessive charging, the potential of the pin 3 of the controller U1 is higher than the potential of the pin 2 thereof, so the pin 1 thereof outputs a low potential to the base level of the transistor Q1, the transistor Q1 is cut off, after the transistor Q1 is cut off, the base level of the transistor Q2 connected with the collector thereof is high, namely the transistor Q2 is conducted, then the light-emitting diode LED2 connected with the collector of the transistor Q2 is electrified and emits light to indicate the charging state, meanwhile, the relay J1 is electrified and starts to act, the normally closed contact J1-1 thereof is switched to the position, namely, the silicon solar battery component starts to charge the storage battery B through the diode D1.

At the same time, the relay J1 is released, namely the normally closed contact J1-1 thereof opens the charging circuit, and the LED1 lamp shines again to indicate that the charging is stopped.

When the voltage of the battery B is larger than the preset voltage value of excessive discharge, the potential of the pin 3 of the controller U2 is higher than the potential of the pin 2, the pin 1 outputs high potential to the base stage of the transistor Q3, the transistor Q3 is turned on, after the transistor Q3 is turned on, the base stage of the transistor Q4 connected with the collector of the transistor Q3 obtains low level, namely the transistor Q4 is turned off, and then the light-emitting diode LED3 connected with the collector of the transistor Q4 loses power and stops emitting light. At the same time, the relay J2 is released, the normally closed contact J2-1 is closed, and the light emitting diode LED4 of the circuit is powered and emits light, so that the load works normally. When the terminal voltage of the storage battery B is gradually reduced when the storage battery B discharges to a load, when the terminal voltage is reduced to a voltage value smaller than a preset excessive discharge voltage value, the potential of a pin 3 of a controller U2 is lower than the potential of a pin 2 of the controller U, a pin 1 outputs a low potential to a base level of a transistor Q3, a transistor Q3 is cut off, after the transistor Q3 is cut off, the base level of a transistor Q4 connected with a collector of the transistor Q4 is high, namely the transistor Q4 is turned on, a light emitting diode LED3 connected with the collector of the transistor Q4 is electrified and starts to emit light to indicate that the storage battery B is in an excessive discharge state, meanwhile, a relay J2 operates, a normally closed contact J2-1 is disconnected, and the light emitting diode LED4 on the circuit.
