inverter mppt 80a solar charge controller

  On the left is a screenshot from the Maui Solar Software "PV-Design Pro" computer program (click on the picture for full-size image). If you look at the green line, you will see that it has a sharp peak at the upper right - that represents the maximum power point. 

What an MPPT controller does is "look" for that exact point, then does the voltage/current conversion to change it to exactly what the battery needs. In real life, that peak moves around continuously with changes in light conditions and weather. into the battery.

  Charge priority or load priority support battery and lithium battery Various battery types support battery-free mode.

   The main function of the MPPT controller: the DC voltage and output current of the main circuit are detected, and the output power of the solar cell array is calculated, and the maximum power point is implemented. The disturbance resistor R and MOSFET are connected in series. When the output voltage is substantially stable, the average current flowing through the resistance is changed by changing the duty cycle of the MOSFET, thereby generating current disturbance. At the same time, the output current and voltage of the photovoltaic cell will also occur. Measure the output power and voltage of the photovoltaic cell before and after disturbance to determine the direction of the next cycle disturbance. When the interference direction is correct, the output power of the solar panel will increase. The loop continues to disturb the same direction, in contrast, is disturbed in the opposite direction. Thus repeated disturbances and observations, the output of the solar photovoltaic plate reaches the most objective power point.
