The comparison of the power DC/AC. the period of the inverter 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 THDv THDi of every value of every THDv There will be no need to worry intensity 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).
