The Charger Circuits / Circuit Battery - Charging Regulator is capable of charging a 12-Volts battery at up to six ampere rate. Other voltages and currents , from 6 to 600 Volts and up to 300 Ampere , can be accomodated by suitable component selection. When the battery voltage reches its fully charged level , the charging SCR shuts off , and a trickle charge , as determined by the value of R4 , continues to flow. See Circuit Battery - Charging Regulator below : Circuit Battery - Charging Regulator You can use the circuit to charge : Cells battery  Accu wet and dry Rechargeable battery

Introduction       The PV applications could be grouped according to the scheme of interaction with utility  grid: grid connected, stand alone, and hybrid. PV systems consist of a PV generator (cell, module, and array), energy storage devices (such as batteries), AC and DC consumers and elements for power conditioning. The most common method uses the PV cells in the grid network. However, to understand the performance and to maximize the efficiency of the irradiation of the PV cells, the standalone PV cells have spurred some interest, especially, in the area of the solar tracker system.       Over the years, test and researchers had proven that development of smart solar tracker maximizes the energy generation. In this competitive world of advanced scientific discoveries, the introductions of automated systems improve existing power generation methods. Before the introduction of solar tracking methods, fixed solar panels were positioned ...

 Single microcontroller based 12v to 230v inverter with intelligent battery charging (Made by me) Here I describe the circuit as: *single microcontroller/controller (ATMEGA16/32) *no op-amps, only chips are the micro, opto-couplers and regulator (7805) *low-battery/overload/short-circuit protection *thyristor controlled battery charger, using the MOSFET body diode as the AC-DC rectifier *charger maintains the battery voltage (top) between 13.2-13.5v (adjustable) to maximize the battery life *6-LED display *Only 93 parts in entire control circuit *Delay between switchover to prevent inrush current The method used here, described for those who may benefit from it: -Initialize all ports and peripherals[ADC, Timers, Compare Modules] -Initialize interrupts for Timer0 and compare module for -For PWM, use Timer1 and 16-bit Phase and Frequency Correct PWM mode so the PWM runs completely on the hardware level without need for interaction to keep it running -The AVR senses whether mains is p...
