It's not about loosing the voltage. If we connect 17v panel to 12v battery, which is, for example at 12.0v. The voltage on the terminals of the battery will start increasing from 12.0 till.. until the pulse ends. The charging current is proportional to difference between open circuit voltages. Lets say we don't want to charge higher than 14.4v. when we'll reach that voltage the controller should end the pulse. While not charging the voltage on battery terminals will go down to 12.x -13.x pretty fast. Then next pulse kicks in. We're loosing power between the pulses and it has nothing to do with voltage diff. Mppt has regulated voltage output so it charges constantly thus not loosing power. It also able to pull as much energy from panels as possible.
Please also 1 question: I have total 12 panels each 700 watt with 48.6 VOC. Can i link them to 1 mppt tracker ranges between 90v to 520 v ? My inverter is SOLIS HYBRID 8KW PRO
@@acectrl What I wanted to say was whether it could actually increase the amperage by reducing the voltage. For example, while a solar panel that provides 15 volts and 7 amps is charging a 12 volt battery, the mppt device can output 14 volts and more than 7 amps. In this case, the 7 amperes coming from the panel are increased.
Hmm, I stopped watching at 1:00 when the maths was so obviously wrong. 12v x 10.8A is 129.6W (not 129.8), a small error, but the efficiency calculation is so far out of whack that anything else you say can not be treated as reliable. 129.8/130 is close to 100% as any ten year old could tell you.

Good explanation.
In other words, can the MPP device give a higher amperage value than the amperage value given by the panel?
MPPT cannot provide a higher amperage than what the solar panel is capable of. However, it can optimize the efficiency of the panel's output

@@acectrlyou say the opposite at 0:44
Yes but at a lower voltage
