Every solar installation business knows that in order to provide great products and services to their customers, all of their solar panels and systems should be of high quality. This means that every component, both big and small, should be in prime condition so that the output the panels or systems produce is exemplary. If you’re a solar installation business yourself, then you should know by now that one important component you need to make sure that is of high quality is the solar charge controller.
What Is A Solar Charge Controller?
Generally speaking, solar charge controllers are the ones that regulate the energy flowing from the PV array and transfer it directly to the batteries as a DC-coupled system. Hence, a solar charge controller makes sure that batteries are given the longest life possible, thus making it an incredibly important component of any solar system.
Currently, there are two kinds of charge controllers that exist. The first kind commonly referred to as the “standard,” is small and features pulse-width modulation (PWM). The PWM technology sends out short controlling pulses to the batteries, and for a lot of solar professionals, it’s not particularly agile. For instance, it lacks the ability to optimize an entire array based on differences between panels. Because of this, solar professionals usually consider PWM as old school and not very efficient.
On the other hand, the second kind of charge controller is the one that has maximum power point tracking (MPPT) technology. The MPPT technology can usually be found in larger systems and offers higher performance through its ability to extract all available power from the panels. Moreover, MPPT charge controllers increase a solar array’s effectiveness by 30%, thus making it the preferred technology, but the most basic systems.
