1. solar panels on time and can track the highest voltage and current VI Then made the inverter discharge to power grid with the highest efficiency The peak voltage Vpp of the solar panels is about 19 5V when it in factory And the environment temperature is 25 C The reason of setting this temperature interestingly different from the subjective imagination we ordinary people the conclusion may let us surprised is that when the weather is very hot solar panels peak voltage will fall to about 17 5 V while in cold weather the peak voltage can achieve 20 8 V Now we back to contrast the difference of MPPT solar energy grid inverter and traditional inverter The traditional solar inverter is a bit like the manual gearbox When the engine speed increase while the gearbox gear don t increase at the same time it will definitely affect the speed of the car For traditional inverter speaking the parameter output power is been set in factory It likes a car have been fixed set on fixed 1 gears no matter how powerfully you trample accelerator the speed of a car IS limited While have the MPPT function it will be different it is automatically It will automatically adjust the gears according to the engine speed so it can make cars in the most gears in a reasonable efficiency standard operation It means the MPPT controller can track the maximum power point of solar panels in real time then express the biggest efficiency of solar panels The higher t2. adjust from the maximum to the minimum 4 In automatic adjustment process we will see the LOW light flashing And the power will keep as a starting point from 0 to the maximum output power and it will restart at most for 6 times then locked in the maximum power the ST lamp long bright 5 It need 10 minutes for 6 grade power search Wide voltage input 22 60VDC Achieve wide voltage input I DC voltage input 22 60VDC 2 Second level power variable voltage conversion High frequency two way and one way grid function I High frequency direct modulation AC half wave synthesis 2 Two way grid means Load consume directly And can reverse AC current transmission 3 One way grid means Load consume directly And banned reverse AC current transmission Kinds of frequency output function It can apply to 50Hz and 60Hz frequency of AC Frequency range 45Hz 53Hz 55Hz 63Hz directly connected to the solar panels do not need to connect the battery Using precise Dynamic differential pressure type MPPT function APL functions the inverter automatically adjust the solar panels of maximum output power simply connect the solar panel to the grid inverters Do not need to connect the battery I Differential pressure type MPPT 0 1 V accuracy 2 Power lock 10W AC output AC 0 angle with high precision auto detection AC phase angle of 0 through isolation amplifier then input to the MCU for high precision detection and analysis The pha
