Abstract
The out properties are compared and analysed between serial PWM and soft switching MPPT off-grid PV controller by measurement and simulation. The out voltage waveforms in different stages of the two kinds of PV controller are given. It is pointed out that the batteries' life of serial PWM controller is shorter than that of soft switching MPPT controller due to their different controlled properties of the peak voltages. Two kinds of the PV controller's mathematical models are given. The output power curves varied with battery voltage, irradiance and temperature are calculated by emulation mode, The result shows that the output power of soft switching MPPT controller is averagely 26% higher than that of serial PWM controller under the standard conditions. The difference will be bigger with the higher irradiance or lower
