A solar charge controller regulates the voltage and current or amperage coming from the solar panels going to the battery and prevents the solar panel from overcharging the battery.

A charge controller is the layer of protection for your solar system. Charge Controllers are designed to protect the battery from overcharging and to prevent reverse current to panels during the night. They also regulate the voltage that comes from the solar panel which can vary with the sun conditions and may peak as high as 26 volts for a 12-volt nominal output solar panel. The solar charge controller manages the charging of your 12V battery. Once the battery is full the solar charge controller stops the respective solar panel from overcharging your 12V battery and prevents reverse current. When the charge of the battery goes down, i.e. voltage goes down, the charge controller will sense this and allow the solar panel to recharge the battery.

A solar charge controller is needed when you have 15 Watts of solar energy or more.

No, solar systems are designed to be permanently installed.

The 30-amp solar charge controller has a maximum input of 450 Watts from a solar array. The 30-amp solar charge controller is designed for a 12-volt system only. 12-volt nominal output solar panels should be connected in parallel to keep the voltage at 12 volts.

Yes, each solar charge controller has a blocking diode installed within the wiring.

Yes, this charge controller comes with a 1-year limited warranty.
