What Is The Difference Between MPPT & PWM?

 MPPT stands for Maximum Power Point Tracking. It observes and regulates the energy going from the solar panel to the batteries. Solar panels have a variable output depending on the light available. The devices can match the panel’s voltage with the battery voltage to maximise charge efficiency.

PWM stands for Pulse Width Modulation. The devices can be explained as electrical switches between batteries. It can be quickly switched on and off. Which allows the desired voltage to be obtained to charge the batteries.

So what is the difference?

MPPT charge control devices are more efficient. The current is drawn out of the panel at the panel.

Where as a PWM device, the current is drawn out of the panel at just above the battery voltage. This is not to say that PWM devices do not have place in a system set up.

PWM devices are a good low cost option for small systems where the efficiency of the system is not critical such as trickle charging. Also it’s good for panels with a maximum power voltage of up to 18V for charging a 12v battery.

MPPT controllers are best for larger systems where additional energy harvesting is worth while and the solar array voltage is substantially higher than the battery voltage. An example of this is using house solar panels to charge 12v batteries.

 

Technology & Innovation, State of the Art manufacturing and collaboration with the world’s largest battery manufacturer Johnson Controls has allowed the AMARON® brand to fast become a global leader in the ultra competitive battery market.

 

AMARON® batteries have forged a strong name in Australia due to their incredible value and outstanding quality and reliability on Australia’s rough roads and harsh climatic conditions. AMARON® manufacture a range of batteries to suit most Automotive, Industrial and Commercial applications.

 

Striking the ultimate balance between quality and value, AMARON® has forged a strong reputation for ultra long service life under the toughest of conditions. AMARON® batteries offer excellent value for money due to significantly increased service life and can be stored safely without detrimental loss of charge up to 3 months after charging, making AMARON® the perfect battery for those which see only seasonal or occasional use of their vehicle.

 

Made in India to suit the harsh and demanding native environment, each battery features a rugged design and patented technology which combine to deliver performance at the price which is only a small premium over that of conventional flooded type alternatives.
