PWM Charge Controllers

Solar PV is a straightforward proposition in its basic form. You will only need to hook a solar panel up to a DC load. Once the sun goes down, it will transform solar energy into electricity. Connect the panel to a grid-tied inverter to send electricity to the utility as long as the sun is shining. All is easy until the sun stops shining

In the night time or when the grid is down, the complications begin. It mainly concerns the energy storage section. Solar batteries are linked with the inverter that stores the electricity for further use at night or when the grid is not working. A solar charge controller becomes one of the most critical device components once a battery is added.

What does A Luminous Solar Charge Controller do?

A solar charge controller is like a regulator. It supplies power to system loads and the battery bank from the PV array. The controller will taper off the charging current when the battery bank is almost full, maintain the necessary voltage to charge the battery completely and keep it topped off.

The solar controller protects the battery by controlling the voltage. Luminous Solar Charge Controllers are needed to charge a solar panel battery without overcharging them. Along with this, they also prevent the reverse flow of electricity at night.

The two principal types of solar charge controllers are the PWM (Pulse-Width Modulation) and MPPT (Multiple Power Point Tracking).

PWM or Pulse-Width Modulation charge controllers are simply a device that connects the battery with a solar array. These charging controllers use algorithms to measure the amount of charge that goes to a battery and gradually taper off charging once the battery becomes fully charged. One of PWM controllers' most important advantages is that they have been around for many years, are not expensive, and are accessible in different sizes for different applications.

Here are some of the features of a Luminous PMW solar charge controller:

1. Protection against overcharge and reverse current

Luminous Charge Controller charges solar panel batteries without overcharging and stops the reverse current flow at night.

2. USB Port

This Charge Controller comes with a USB port that gives the flexibility to charge your DC devices such as cell phones directly without using an adapter.

    Frequently Asked Questions:

    1. What are the features of a Luminous PMW Charge Controller?

  • 98% efficacy
  • Inbuilt Low Voltage Disconnect (LVD)
  • Automated battery selection
  • USB port for DC load connection
  • 2. How Can You Check Whether Your Solar Controller is Working or Not?

    To check if your solar charge controller is working or not, disconnect the positive cable between the solar battery and charge controller. Measure the current by linking the positive test lead from the multimeter to the controller's positive line. The negative test leads from the multimeter are connected to the positive terminal of the solar battery.

    3. Can solar panel overcharge battery?

    You can control the voltage and current coming from the solar panels that go to the battery. Most '12 volts' panels put out about 16 to 20 volts, causing battery overcharging issues if there is no regulation. It is where you need a solar charge controller.

    PWM & MPPT Solar Charge Controllers | Luminous India

    Description: PWM (Pulse Width Modulation) and MPPT (Multiple Power Point Tracking) control the current and voltage flowing from the solar panels to the batteries. Furthermore, these controllers safeguard the batteries from getting deep discharged and prevent the reverse flow of current from batteries to the solar panels at night. As a result, the solar charge controllers are a vital component of the setup.

    What is a Solar charge controller?

    A solar charge controller is a device that aids in the charging of batteries using the solar energy supplied by solar panels while preventing overcharging. While all is easy until the sun stops shining, solar panels can generate electricity at extremely high voltages and currents. If all of this is supplied straight to the battery, it may get overcharged, resulting in shortening its lifespan.

    The controller prohibits this by monitoring the current and voltage levels, and is usually installed between the solar panels and the battery bank to control the solar charging of the batteries. For instance, if your solar panel produces 20V and your battery is 12V, it will ensure that only 12V reaches the battery.

    Solar charge controllers also prevent the deep discharge of batteries and prohibit reverse current flow from batteries to solar panels at night. Essentially, solar energy cannot be properly used to charge batteries without the assistance of a charge controller.

    What does A Luminous Solar Charge Controller do?

      1. Enables Prevention Of Reverse Current at Night

    Solar batteries run the risk of passing small amounts of current back to the solar panels at night. This can lead to a discharge from the battery, causing damage to the solar panel. This is where a solar charge controller plays a crucial role by preventing the passing of reverse current during night-time. Hence, safeguarding your solar panels against damages.

      2. Prevents Overcharging Of The Battery

    Since a solar battery can't hold any incoming energy when it's fully charged, it's critical to keep it from receiving any further energy. For the same, a solar charge controller is useful. When a battery reaches a certain voltage level, the controller interrupts the energy flow and prevents overcharging.

    MPPT (Maximum Power Point Tracking) Charge Controllers

    MPPT charge controllers are more advanced than PWM charge controllers. They enable solar panels to operate at their maximum power. MPPT charge controllers operate according to the panel voltage and convert the extra voltage of the panel into a current, increasing the output from the solar system.
