Solar Panel Charge Controller Low Voltage Disconnect Circuit

The first low dropout voltage ldo solar charger controller circuit using transistors makes use of a basic differential amplifier along with series p channel mosfet linear regulator their compatible use seems as if a relationship created by great beyond.

Solar panel charge controller low voltage disconnect circuit.

A charge controller or charge regulator is basically a voltage and or current regulator to keep batteries from overcharging. The spc3 is a solar power center it can handle all of the power functions for a solar charged 12 volt dc system. Voltage output is adjustable. It is mainly intended for charging 12v lead acid batteries.

Most 12 volt panels put out about 16 to 20 volts so if there is no regulation the batteries will be damaged from overcharging. Short circuit between the positive and negative terminals of the battery or short circuit between the positive and negative wires of the terminal may cause fire and explosion before connecting the battery to the solar system make sure the battery voltage is higher than 6v then start the controller if the system is 24v make sure the. 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 spc3 contains a 9 amp photovoltaic charge controller a 10 amp low voltage load disconnect circuit and a pair of built in white leds for area illumination.

Voltage output is variable. In our case we connect the ve of the solar panel to the pole of the relay and ve of the battery to n o when the battery is connected to the scc solar charge controller the circuit check the battery voltage the voltage is less than or equal to lower limit the current is flows to the battery and battery start charging.
