What is MPPT Solar Charge Controller?

1. What is MPPT Solar Charge Controller? A solar charge controller is one of the most vital parts in a solar power system that uses battery backup. As a matter of fact, it is the center of the system which controls the power entering the batteries from the solar panels. If you pick a high-quality solar charge controller, it will improve the efficiency of your system by as much as 30 percent. Unlike other types of charge controllers, Maximum Power Point Tracking is the best type of solar charge controller that assists you to get the most from the solar panels and greatly increase battery life. Due to their high-efficiency, the best MPPT solar charge controllers have been highly used in off-grid solar power systems and in RV solar systems than any other charge controller. With this in mind, it is important that you get the best MPPT solar charge controller for your off- grid home or RV. But before that, let’s define what MPPT solar charge controller is and how it works. MPPT charge controller Maximum Power Point Tracking normally referred to as MPPT is an electronic system that operates the Photovoltaic (PV) modules in a way that enables the modules to produce all the power they are capable of. Note that MPPT is a fully electronic or digital system that varies the electrical operating point of the modules so that the modules are able to provide maximum available power.

2. In short, the Maximum Power Point Tracking charge controller looks at the output of the solar panels and compares it to the battery voltage. The device then figures out what is the best power that the panel can put out to charge the battery. Thereafter, it takes this and changes it to the best voltage in order to get maximum AMPS into the solar batteries. A good number of the most recent top MPPT solar charge controllers are around 93 to 95 percent efficient in conversion, nevertheless, some of the best MPPT charge controllers can go up to 97 to 99 percent. The real gain can vary greatly depending on the temperature, weather, battery state of charge, and some other factors. How do I size my MPPT charge controller? Sizing solar charge controllers is very easy. This is because solar charge controllers are rated by voltage and current. These ratings depend on your solar arrays current and battery voltage. Thus, solar charge controller sizing normally involves getting a charge controller huge enough to handle the level of power and current generated by your solar power system. How does a Maximum Power Point Tracker Works? The MPPT is a high-efficiency DC to DC converter. They work by taking the DC input from the solar panels, then convert it to high-frequency AC, and convert it back down to a different DC voltage and current to exactly match the panels to the batteries. The power point tracker functions at extremely high audio frequencies of around 20 to 80 kHz range. At what conditions are MPPT solar charge controllers very effective? When there is a low battery charge – the lower the condition of charge in your battery, the more current an MPPT passes into them.

3. During Cold weather, cloudy, or hazy days – during this time, you will find that the Sun hours are low but you still need to recharge batteries. The MPPT works best at such times and you will have nothing to worry about. Long wire runs – Most of the best MPPT charge controllers enable you to utilize your solar panels with a higher voltage output than the operating voltage of the battery system, which permits much smaller gauge wire to be utilized.
