The result of the comparison of DC/AC voltage side of the inverter.Make a same-side electrical production of solar cells, which have the same type and size.The intensity of the Sun, (PV type Mono-si 300W) The difference of the electrical production of solar cells with a type of different sizes, different electrical power (PV. Type Mono-si 300W) against (PV types Poly crystalline 260W).Output power of the inverter side dimensions 300W 300W [1] and [2] will have similar Output. Part of the Output power of the inverter 600W size will be twice the size, 300W. And the Output of the inverter 1500W are sized to be 2.5 times the size 600W. And about five times the size, 300W Per-unit from using the system to analyze the Output voltage levels will be the same in all levels of sunlight intensity. Efficiency of the inverter. When comparing the proportion of DC/AC power Will find that the performance of your inverter 1500W will cost more than 600W for about 2-3% And more than 300W of about 5-6%. For the harmonic value bindings (THD) of the inverter and inverter both THDv all THDi.The value of all levels will have the same THDv intensity sunlight is THDv = 2.1%.Be based on the requirements of the electricity (PEA). Values of THDi inverter 300W 300W [1] and [2]. Measuring value detection not because power has very low value. Inverter 600W has more than 1500W inverter THDi value equal to 24.4%. In accordance with the regulations of the electricity authority (PEA).
