Phoenician Energy 30A Solar Charge Controller

The charge controller also provides a USB output for charging phones or other 5V appliances.

Advantages: Fully Automatic 4-stage Battery Charging Process, Adjustable operating modes of loads, and power rate with USB output.

This charger controller is built-in with a larger buffer battery for storage of solar energy. The included 5W power panel has a built-in regulator to prevent solar overcharging. The control status is shown on the IIC port of the Arduino and then displayed on the LCD when displaying data.

Phoenician Energy 30A solar charge controller has 12V battery charging port, used to charge the battery.

Advantages: With this kind of function, we can protect 3.2V or 12V lithium battery controller from damage by reverse polarity connection.

The solar regulator is only suitable for lead-acid batteries: OPEN, AGM, GEL, not for nickel hydride, lithium, Liions, or other batteries. For protecting the lifespan of your battery, once the voltage of the battery drop below 8V, the solar controller will turn off automatically.

Waterproof, dust-proof, protection against overcharged/over-discharge, and short circuit. With an input voltage of 20 to 40V DC (e.g. when the solar panel output is strong), this controller can work with the batteries that have a rated voltage of 20V or above, which will be discharged at 25A constant current and recharge at 0.5A to 1A constant current

Solar Charge Controller FAQs

What does a solar charge controller do?

A charge controller or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery.

How big of a solar charge controller do I need?

You typically want to make sure you have a charge controller that is large enough to handle the amount of power and current produced by your panels. Typically, charge controllers come in 12, 24, and 48 volts. Amperage ratings can be between one and 60 amps and voltage ratings from six to 60 volts.

What is the difference between MPPT and PWM charge controller?

With a PWM controller the current is drawn out of the panel at just above the battery voltage, whereas. With an MPPT controller the current is drawn out of the panel at the panel “maximum power voltage” (think of an MPPT controller as being a “smart DC-DC converter”)

Wrapping Up 

Take control of your electrical costs in the most convenient way possible with a solar charge controller. The good news is that a solar charge controller is none of those things. A solar charge controller makes sure that every device in the system works perfectly. It automatically regulates the power usage and makes sure that it’s clean and safe. The solar charge controller, which acts as a central communication point for the battery bank, ensures your system runs better than ever before, but only if you use it with these five devices.
