The comparison of the power energy DC/AC of the inverters to the equality of the power capacity of solar cell with type and size as the intensity of sunlight, had. A kind of PV Mono-si 300W.
And the difference of capacity of solar cells with different type and size that is different, electric
A kind of PV Mono-si 300W compared with PV type Poly crystalline 260W.
The power of the inverter Output size 300W [1] and [2] 1 300W*2 is output nearby.
Part of the inverter power Output size 600W will be twice the size of 300W and Output of inverter, the size 1500W. A 2.5 times the size and 5 600W approximately twice the size 300W.
By using system analysis Per-unit is equal in every level electric power Output intensity sunlight.
The performance of the inverter. Comparing the proportion of power DC / AC will find that the efficiency of the inverter of 1500W be worth more 600W about 2-3% and more. 300W about 5-6%.
For the harmonic THD include () of the inverter and the inverter THDvTHDi of every value of every THDvThere will be no need to worryintensity sunlight.
Is THDv = 2.1% can follow the requirements of electricity (PEA).
The THDi inverters 300W [] and [] 1 300W 2 detection measure value is not due to low power
The inverter is more 600W THDi inverter 1500W was 24.4% not follow the requirements of electricity (PEA).
