AI Customer ServiceThere is a loss in every link of energy from solar radiation to photovoltaic modules, through DC cables, confluence boxes, DC distribution to solar inverters in photovoltaic system. As shown in the figure, the DC side loss
AI Customer ServiceAn important consideration in calculating inverter size is the solar panel system:inverter ratio. This is the direct current capacity of the solar array divided by the maximum alternating current output of the inverter. For example, a 3kW solar panel system with a 3kW inverter has an array-to-inverter ratio of 1.0.
For example, a 3kW solar panel system with a 3kW inverter has an array-to-inverter ratio of 1.0. The same array with a 5kW inverter would have a system:inverter ratio of 1.2. Most solar installations have a ratio slightly above 1, but usually no more than 1.25. The highest ratio generally recommended is around 1.5.
The general guideline is to choose a solar inverter with a maximum DC input power of 20-35% greater than the total capacity of the solar array. It ensures the unit can handle periods of peak production without getting overloaded. Installers typically follow one of three common solar inverter sizing ratios:
Most installations slightly oversize the inverter, with a ratio between 1.1-1.25 times the array capacity, to account for these considerations. The size of the solar inverter you need is directly related to the output of your solar panel array. The inverter’s capacity should ideally match the DC rating of your solar panels in kilowatts (kW).
The maximum recommended array-to-inverter ratio is around 1.5-1.55. Oversizing the inverter too much can lead to increased costs and inefficiencies, while under sizing can result in clipping, which is when the inverter can’t handle the peak power output from the solar panels, leading to energy losses. Solar Array Size
The output of a solar PV system is dependent on the availability of the sun. Because the output of panels may only reach peak DC capacity a few hours out of the year, it may not be cost effective to size an AC inverter to capture that full output.
