MPPT Solar Charge Controller MPPT-30A
Feature:
The most important feature of this controller is intelligent tracking input voltage from solar panel, which could let solar panel always working at Maximum Power Point of V-A curve. Compared with normal solar charge controller, this MPPT controller could increase 10%-30% electrical power using efficiency from solar panel.
 Schematic Diagram:
The picture on the right shows typical 12V battery solar charge system V-A curve. Normal Solar Charge Controller:
Solar Panel works at point A state, the solar panel working voltage is a little higher than battery voltage. Charge Voltage: UA=13.2V Charge Current: IA=9.8A Charge Power: PA=13.2*9.8=129.36w Area in drawing: ①＋③ MPPT Solar Charge Controller:
Solar Panel works at point B state, the solar panel working voltage much higher than battery voltage. Charge Voltage: UB=18.4V, Charge Current: IB=9.3A Charge Power: PB=18.4*9.3=171.12w Area in drawing: ①＋② Comparison:
The power B is more than power A. △P/ PA =（PB— PA）/ PA＝32.3% As a result of different manufacture of solar panels,different solar illumination intensity,different temperature,different efficiency of solar charge controller and so on.The effective power increase rate is 10-30%
Function:
This MPPT solar charge controller is not only have above mentioned special function, at the same time including completely Protecting and Controlling functions:
Overcharge protection
Over discharge protection
Battery Reverse Current Protection
