How does a solar charge controller work and why do you need one?

Solar charge controllers can prevent battery over-discharging by disconnecting the DC loads when the battery is at a low capacity. This is mainly done through the Low Voltage Disconnect (LVD) feature.. The lower the state of charge (SoC) of a battery, the lower its voltage. In the image below, you can see the voltages of a typical Lead-Acid battery vs its state of charge:
