Best Solar Charge Controller

Best Solar Charge Controller

Today, solar energy is the cleanest and available renewable source of energy. A photovoltaic module or solar panel system with the help of direct Sunlight and transfer it to solar batteries by managing the voltage with the solar charge controller. It helps in maintaining the voltage between the solar power system and the batteries. As a result, you use the power in the form of correct voltage electricity.

What is a solar charge controller?

The solar charge controller manages the power supply in battery banks from the solar panels. It ensures that the battery cells not overcharged during the day time, and power doesn't go back into solar panels and drain the battery. There are some advanced charge controllers come with the lightning and load control, but the primary job is always to manage the power.

Types of the solar charge controller

There are two types of charge controller technologies PWM and MPPT.

1)      PWM or pulse width modulation

PWM or pulse width modulation

Solar Charge Controllers work/operate by making a direct connection from the solar panel to the battery cells. Solar panel's power output voltage pulled down by the PWM to the battery voltage during the day time when charging is in bulk because of the continuous process of connection from the solar panel system to the battery cells.

Solar panel's voltage output rises because of the rise in battery voltage as the battery start charges. That means you have to make sure to match the nominal voltage of the solar panel with the battery's voltage.

When we install a 5kw solar panel in Brisbane, it means it works with the 5V of the battery. The actual voltage of a 12V solar panel system is nearly 16Vmp when it connects with a load because it requires a higher source of voltage to charge a battery. If both solar panels and solar batteries start with the same voltage, the battery would not work and charge.

12v solar panel can charge the 12v of battery. A series of two 12v panel=24v can charge a 24v of battery. But if you are charging a 12v battery with the 24v of the solar panel system, you are throwing/wasting half of the panel's power. If you try to charge a 24v of battery with the 12v of the panel, you are wasting 100% of the panel's potential power as well as draining the battery.

2)      MPPT or maximum power point tracking

MPPT or maximum power point tracking

Solar Charge Controller, it's a technique to maximize the power extraction under all conditions. As we know, all the solar power systems have a complex relationship with weather and temperature, so as a solar panel. MPPT supply the maximum power to the batteries for use when it's not sunny or dark outside.

Lower voltage of the battery can charge through a higher voltage of the solar panel. Like a 20v of solar panel can charge a 12v of battery, or two series of 20v can charge the 24v of battery, or three series of 20v can charge up to 48v of battery. It opens up the full chances of a broader range of solar arrays that can use with an off-grid solar power system.

Key features of the solar charge controller

Ø  It stops wastage of power supply.

The solar charge controller fulfills the main reason for installing the solar power system, which is no to waste electricity.

Ø  Prevents battery from overcharging and draining by controlling voltages.

It maintains the power voltage of current automatically; it prevents battery from draining and overcharging.

Ø  It minimizes the chances of a short circuit by 99%.

The main fear of any electrical item is a short circuit; the solar charge controller maintains voltage, which minimizes the chances of any electrical fault.

Ø  Highly reliable.

Consistently good in quality, performance, and trusted for low and high voltage electricity problem.

Ø  Monitor all reverse power supply flow.

Mostly problem this occurs in solar power systems is the reverse supply flow of power. The solar charge controller helps in maintain that flow.

Uses of the solar charge controller

1.      Power supply to battery banks.

Primary work of every solar charge controller, to charge and supply power in properly.

2.      It controls the device voltage.

After the charging process, it takes care of proper electricity voltage supply

3.      Auto indication of full and low battery charge.

It indicates and manages if the battery percentage is full or low.

4.      Monitors the overload and minimum voltage.

The solar charge controller monitors the overload and minimum voltage power supply and makes it stable for the use.

More about solar charge controller

Lately, in the market of solar power systems, the solar charge controller comes with some new and advanced features, including the increased capacity of operating the higher voltages to manage the larger systems from before.

As we all know, moving towards solar energy is a good step but, setting up it in houses and offices become risky without the whole setup, which includes solar inverters, batteries, and most important a solar charge controller which controls the voltages and supply it properly for the better use.

As I mentioned above, it prevents solar battery from many types of problems like overcharging and reverse flow of electricity because of low and high voltages of power supply. You cannot control Sunlight, as it travels from a long distance and direct lands on the solar panel. To manage that potential energy, a solar charge controller is a mediator between panel and battery, which helps in maintaining the voltage of power so that we receive power in a perfect voltage for use.


By only installing a Solar Panel Systemat your rooftop is not enough. For a better experience, you have to install a perfect setup, which includes a solar panel, solar batteries, solar inverter, and most important Solar Charge Controller in Brisbane, QLD. That gives you the best power supply without any electrical fault or short circuit.

Around half of the residential and commercials owners are using Solar Power System in Brisbane. Sunny Sky Solar offers a great range of solar power installer services, including solar panels, solar inverters, solar batteries, and now in solar charge controller etc.
