Simple Solar Panel Regulator Circuit

The pot or the preset is used to accurately set the voltage level that may be considered as the safe value for the battery.

Simple solar panel regulator circuit.

It is mainly intended for charging 12v lead acid batteries. Here is the simple circuit to charge 12v 1 3ah rechargeable lead acid battery from the solar panel. And for good reasons. Solar panel charge controller wiring intro solar panel charge controller wiring diagram and step by step guide for off grid solar power system wiring.

This low dropout voltage ldo solar charge controller uses a simple differential amplifier and series p channel mosfet linear regulator their compatibility seems like a marriage made in heaven. The first part of a solar circuit is a device for collecting sunlight. Using a current control feature the specialty of the design is that it incorporates a current control feature also. This circuit may also be used to charge any battery at constant voltage because output voltage is adjustable.

The shown solar panel regulator circuit is framed as per the standard mode of the ic 338 configuration. A solar regulator is a small box made up of circuitry in a solid state that is located between a battery and a solar panel. This solar charger has current and voltage regulation and also has over voltage cut off facilities. Voltage output is adjustable.

The input is given to the shown input points of the ic and the output for the battery received at the output of the ic. Photovoltaics the process of making electricity from sunlight is growing in popularity among alternative energy enthusiasts. Connecting the solar panel charge controller mppt or pwm are the same solar battery and the pv array in the right way is the essential work before enjoying the solar energy. This circuit uses the solar cell for dark detection this charges the batteries and turns the led on when the solar cell is in the sun or turns off the led when the solar cell is in the dark not charging the batteries.

The circuit of a simple lm338 solar battery charger is shown below using the ic lm338. The purpose of the box is to regulate the amount of charge going from the panel that flows into the deep cycle battery bank. The panel that we re using for these circuits is this one part number pwr1241 from bg micro about 3 each.
