Form a complete set:
Solar Panel: 12V solar system should use 40pcs cells laminated solar panel. The maximum power point voltage is18V above. 24V solar system should use 2pcs above mentioned solar panels.
Conductor: The cable between solar panel with MPPT solar charge controller should be better calculated by 1Ampere per 1mm².
Solar Charge Controller: MPPT 10 Amp Model solar charge controller Rated input Ampere is 10A. We have 12V, 24V two kinds of MPPT solar charge controllers (other specifications could be designed as customer special request). Fit for power of solar panels: 20—200Wp(12V), 40—400Wp(24V).

Simply Measure Methord: For 12V system, measure the input voltage from solar panel with multimeter (terminal 1, 2 of controller), it is normal if the voltage of solar panel more than battery voltage 0.5-6V. Generally, the higher input voltage, the better charge efficiency. For 24V system, the input voltage will be much more higher than battery voltage
(Note: It is normal the controller can not find Maximum Power Point within 10 minutes from system start.)
Compared with normal solar charge controller by Schematic Diagram
(Note: It is normal the controller can not find Maximum Power Point within 10 minutes from system start.)
MPPT Schematic Diagram: Picture 2 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

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 30%.
