MPPT(Maximum Power Point Tracking) Solar Charge
Contents
1. 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 Form a complete set Solar Panel 12V solar system should use 40pcs cells laminated solar panel The maximum 0 2 4 6 8 10 1214 16 18 20 22 U v power point voltage is over 18V 24V solar system should use 2pcs above mentioned solar panels 48V solar system should use 4pcs above mentioned solar panels Conductor The cable between solar panel with MPPT solar charge controller should be better calculated by 1Ampere per 1mm Solar Charge Controller We have 12V 24V and 48V three kinds of MPPT solar charge controllers with 10A 20A other specifications could be designed as customer special request Fit for power of solar panels MPPT 20 200Wp 12V 40 400Wp 24V 80 800Wp 48V Connection As Picture 3 according to below process 1 Connected the poles of the battery to the controller 3 4 from left firmly and correctly At this time the LOAD green LED is bright If the LOAD green LED is not bright it is indicate there is battery reverse polarity connection Only LOAD green LED is bright we could continue next step operation 2 Connected the poles of the solar panel to the controller 1 2 from the left firmly and correctly 3 Connected the poles2. of the LOAD to the controller 5 6 from the left firmly and correctly Picture 3 Solar panels MPPT solor controller Simply Measure Method 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 and 48V system the input voltage will be much more higher than battery voltage Note It is normal phenomenon the controller can not find Maximum Power Point within 10 minutes from system start Indicator Picture 1 1 Load indicator green bright indicate there is output Load could work off indicate there is not output and Load can not work 2 Low Voltage Indicator red bright indicate the voltage of the battery is low Load could not normal working This is normal phenomenon When the battery voltage recover to 12 6V or 25 2v the Load will be automatically working at this time the indicator is off 3 Charge Indicator red bright indicate the battery need to charge flickering means float charging off means charge has stop RESET Button Please notice the rated current of your controller if there is short circuit or overload happened the MPPT controller will close output Load indicator off Low voltage indicator off If you need the MPPT controller recover work please check the reasons and clear out the fault fi
3. MPPT Maximum Power Point Tracking Solar Charge Controller MPPT 10 MPPT20 User s manual 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 Function This MPPT 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 Overloading Protection Short Circuit Protection Reverse Polarity Connection Protection 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 ICA Charge Voltage Ua 13 2V Charge Current la 9 8A Charge Power Pa 13 2 9 8 129 36w Area in drawing MPPT Solar Charge Controller Solar Panel works at point B state the solar panel working voltage much higher than battery voltage Charge Voltage Us 18 4V Charge Current IB 9 3A Charge Power Ps 18 4 9 3 171 12w Area in drawing 0 Picture 2 a om NUA NMNANGQG Comparison The power B is more than power A AP Pa Ps Pa Pa 32 3
