How To Choose the Ideal Solar Charge Controller?


    A solar charge controller is a critical component of your solar system installation as it acts as an intermediary between your solar panels and the battery. Additionally, a solar charge controller is responsible for preventing overcharge by controlling the
    amount of charge your batteries receive. It also restricts reverse current flow from battery to solar panels preventing solar panels from getting damaged.

    Plus, it charges the battery at optimum voltage levels, which increases the overall service life of your battery. In this guide, we will have a look at this critical component to get a better understanding of the inner workings of a charge controller. So, let’s get started!

    How Do Solar Charge Controllers Work?
    In almost all cases, a solar charge controller works by passing a charge current through the semiconductor, which is essentially a valve that controls the current. A charge controller also prevents overcharging of the batteries by controlling the
    amount of flow of the energy the battery receives once it has reached a particular voltage.

    Charge controllers are also responsible for other critical functions in a solar system like protection against overloads, disconnections due to low voltage, and blocking reverse currents. Let’s look at why this is important.

    1. Overload Protection: Charge controllers play a major role in preventing battery overcharge. An overcharge occurs when a battery is charged more than its specified voltage, which is much greater than what the circuit can handle, which can lead to overheating or, in other serious cases, even fire breakouts – making the charge controller a very critical component of your solar unit.
    2. Blocking Reverse Current: A solar panel sends current through the battery in one direction; however, during the night, some of that current can pass through in the reverse direction, which results in discharging of the batteries to some extent and also damages the solar panel. A charge controller acts as a valve and blocks a reverse current from taking place.

    3. Is a Solar Charge Controller Required All the Time?
      Normally, yes. However, you won’t typically require a solar charge controller if you have between 1 to 5-watt panels. If your panel is putting out anywhere between 2 watts or less for each 50-battery amp-hours, you don’t require a charge controller. However, it is best to always have a solar charge controller in place to prevent overcharge and for added safety.

    4. Also, if you have a solar power system at your home and are in need of a charge controller, Luminous has an exciting range of charge controllers that are all designed to offer the best in terms of service and quality.

    Priced at ₹1,085, the SCC1210NM Solar Charge Controller helps you charge DC devices directly without using any kind of adapters via the USB port and helps run DC appliances without any glitches. Moreover, it prevents any overcharging and
    reverses flow, helping extend the service life of your batteries.

    Solar Charge Controller – SCC1220NM

    It’s the same version as the SCC1210NM but with a slightly higher rating at 20A and comes at a price tag of ₹2,295. The solar charge controller has a 98% efficiency rate and has an inbuilt low voltage disconnect, and comes with connection terminals
    for DC load connection.

    Solar Charge Controller – SCC1206N

    It’s a highly cost-effective controller that comes at an affordable ₹636 and offers superior protection against overcharge and reverses current and gives you the option to charge your DC devices directly from the controller without having to use
    any adapters.
