Shake it shake it baby low rider song12/16/2023 ![]() ![]() The 2k2 resistor is used to activate or bias the diodes so that it can conduct and enforce the intended 2.1 V total drop. ![]() The drop of 0.7 V across each diodes raises the grounding threshold of the IC by stipulated level forcing the IC to regulate the output at 14.1 V instead of 12 V. The 3 diodes connected at its ground (GND) terminals is introduced specifically to counter this problem, and to upgrade the IC output to about 12 + 0.7 + 0.7 + 0.7 V = 14.1 V, which is exactly what is required for charging a 12 V battery fully. The voltage from a solar panel can vary hugely, depending upon the incident sun rays, andĪs we know the IC 7812 will produce a fixed 12V at the output which cannot be used for charging a 12V battery. Though it might look quite simple, charging a battery from a solar panel is never easy, because of two reasons: The energy from a solar cell or a solar panel can also be effectively stored so that it can be used as per ones own preference, normally after the sun has set or when it's dark and when the stored power becomes much needed for operating the lights. Rechargeable batteries are probably the best and the most efficient way of collecting or storing electrical energy for later usage. Normally there's only one efficient way of storing electrical power, and it's by using rechargeable batteries. Solar energy may be used directly for powering an electrical equipment or simply stored in an appropriate storage device for later use. The main property of this device to convert solar energy to electrical energy has made it very popular and now it's being strongly considered as the future solution for all electrical power crisis or shortages. Solar panels are not new to us and today it's being employed extensively in all sectors. The post comprehensively explains nine best yet simple solar battery charger circuits using the IC LM338, transistors, MOSFET, buck converter, etc which can be built and installed even by a layman for charging all types of batteries and operating other related equipment Overview Must be efficient enough to satisfy the fundamental battery charging needs.A simple solar charger must have 3 basic features built-in: ![]()
