Do you know what’s the meaning of I-Panda smart MPP

Nowadays mppt technical is popular welcome to be used in solar controller, more and more enterprise spend time and money on it, here believing all of you have a question in the heart saying”why ?” before this let’s learn the follows.
1. What the heck is an MPPT charge controller?
MPPT controller is a Solar charger that tracks the maximum power output of the panel to charge the battery.on one hand it optimizes and makes use of the solar panel,on other hand it can protect and charge the battery with three stage charge stages.it saves a lot budget to construct a off grid solar system. please view the follow system, the bold is the I-Panda eSmart solar controller.

2. So what do you mean by "optimize"?
Solar cells and batteries are neat things. Unfortunately, they are not very smart. Most PV panels are built to put out a nominal 12 volts. In actual fact, almost all "12 volt" solar panels are designed to put out from 16 to 18 volts. The problem is that a nominal 12 volt battery is pretty close to an actual 12 volts, generally 10.5 to 12.7 volts, depending on state of charge. Under charge, most batteries want a 13.2 to 14.4 volt to fully charge, it quite a bit different than what most panels are designed to produce. However the MPPT controller can keep the power not reduce and ensure the voltage convert normally either.
3.What is maximum power point track ?
Maximum Power Point Tracking is digital electronic tracking. The charge controller looks at the output voltage of the panels, and compares it with the battery voltage. It then figures out what is the best power that the panel can out put to charge the battery. So get the best voltage and maximum AMPS charge the battery. Most modern MPPT are around 93-97% efficiency in the conversion.So you can increase 30-60% efficiency than the traditional controller,they are all from the MPPT which means maximum power point track.

From this three questions, why I-Panda spend so much time on developing mppt solar controller is clear to us.
