When IC1 has been heating up over defined transistor. It stops! Of course, there is no current to the transistor. So, It gradually reduces heat down. IC1 will return to run again. In normal IC-LM338 Can supply up to 5 amps, but to load current maximum 20 amps, we will bring it to parallel.

By parallel with the transistor Q2, from the Q3 onwards. Each transistor can increase the current of 5A. Solar panel regulators monitor the flow of power between the solar panels and the connected battery. Some regulators may simply disconnect the flow of power when the battery is in danger of overcharging. Others monitor the flow and, when the battery voltage rises to the regulation point, they regulate the flow to hold the voltage at this point for a period of time. This is called the 'absorption' period, and generally allows the battery to become fully charged. The regulator then controls the charge to keep the battery at close to full charge, also known as the 'float' point.IC1 is temporarily stopped responding. Because it is overloaded. By earlier, the current of 1A flow through the IC1 and the SCR1 into loaded directly. Not through all transistors.

Our new Voltage Regulator does one job, simply and effectively — takes an input of 7-40 volts dc and outputs a regulated dc current. The SCR1 is working to hold. Until the power supply is cut off. Which automatically resets itself in this manner is called an Electronic circuit breaker. How much output voltage This power supply is not broken. IC1 can prevent overload very well. Even being a long-short circuit throughout the day. It is still in good condition. It may have more energy a loss in transistors and ICs. Making must use a larger heat sink. It is too consumes more energy than necessary. To measure an S3 or S3H sender (with screw in head) measure from the top of the thread to the bottom of the stem.In the short-circuit conditions. Or Overload, Or Using too many currents. The Q2 is pulled by the current of 5A. Until the voltage of 0.75V drop across R5 – 0.15 ohms. (emitter pin of Q2). Then, this voltage to gate lead of SCR1. Next, it is enough to trigger SCR1 works immediately. Solar power regulators are used to prevent the battery bank connected to your solar panels from becoming overcharged.
