The way that IC works is to use the solar cell both to charge the battery and sense darkness. The output of the solar cell is on the CE (Chip Enable) pin which must be pulled low to turn on the chip. As long as there is enough light to keep the pin at logical high, the solar cell is connected to ground and has a path to charge the battery.
Simple solar charger circuits are small devices which allow you to charge a battery quickly and cheaply, through solar panels. A simple solar charger circuit must have 3 basic features built-in: It should be low cost. Layman friendly, and easy to build. Must be efficient enough to satisfy the fundamental battery charging needs.
Thus this 5V solar battery charger circuit can be considered as an ideal and extremely efficient solar charger circuit for all types of solar battery charging applications. For solar panels with higher voltages, such as 60 V solar panels, the design can upgraded by adding zener diode regulator at pin12 of the TL494, as shown below:
The design is targeted for small and medium power solar charger controller designs, capable of operating with 15 to 60V solar panel modules and 12V or 24V batteries with up to 16A output current. The design uses the perturb-and-observe algorithm for MPPT and has an operating efficiency of greater than 98%.
The ADC output is multiplied four times and displayed on the LCD as battery voltage. When the solar panel voltage is present, the dusk-to-dawn sensor provides a signal to the microcontroller, which then displays 'charging' message on the LCD. During charging, the battery voltage is continuously monitored.
In such situations the battery might need an external charging from mains using a 24V, power supply applied across the solar panel supply lines, across the cathode of D1 and ground. The current from this supply could be specified at around 20% of battery AH, and the battery may be charged until both the LEDs stop glowing.
We know that a 5V solar charger circuit can be easily built using linear ICs such as LM 317 or LM 338, you can find more info on this by reading the following articles: Simple solar charger circuit Simple current controlled charger circuit
