FAQs 6

What is PV module capacity & solar inverter capacity ratio?

The PV module capacity and solar inverter capacity ratio are commonly referred to as capacity ratio. Reasonable capacity ratio design needs to be considered comprehensively in the light of the specific project.

How much solar power can a 5kw inverter produce?

Under the Clean Energy Council rules for accredited installers, the solar panel capacity can only exceed the inverter capacity by 33%. That means for a typical 5kW inverter you can go up to a maximum of 6.6kW of solar panel output within the rules.

Does a solar inverter need a higher DC capacity?

The start voltage required for a solar inverter's operation is specified in its datasheet. A higher DC capacity attached to an overloaded solar inverter may help it attain this start voltage during low light conditions. However, DC overloading may have an indirect benefit of improving the low light performance of the system.

What is the maximum output capacity of a solar inverter?

That is to say, under the condition that the module capacity is equal to the solar inverter capacity, due to the objective existence of various losses, the actual maximum output capacity of the inverter is only about 90% of the rated capacity of the inverter, even when the light is the best, the inverter does not work at full load.

Why should you choose a lower inverter capacity?

It might make sense to choose a lower inverter capacity to improve the utilization of the Solar Inverter. The Normal Module Operating Temperature output given in the Solar Module Data Sheet might be a better Indicator of the actual peak output of the Solar Module under real-time conditions.

Can a solar panel be more than 33% larger than an inverter?

Clean Energy Council regulations dictate that solar panel arrays cannot be more than 33% larger than the inverter they are paired with, otherwise the STC rebate will not be applicable. (The amount of the STC rebate is based upon the DC power output from the array of panels. So in this example, the STC is based on the 6.6kW of panels.)
