Technical FAQs 4

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.

Why does a distributed photovoltaic power station need an inverter?

Because the inverter accounts for only about 5% of the system cost, the number or power of the inverter is reduced by the overmatching of the components in the distributed photovoltaic power station system, and the investment income is very small, which also bring other problems, the specific analysis is as follows.

What is a good DC/AC ratio for a solar inverter?

Because the PV array rarely produces power to its STC capacity, it is common practice and often economically advantageous to size the inverter to be less than the PV array. This ratio of PV to inverter power is measured as the DC/AC ratio. A healthy design will typically have a DC/AC ratio of 1.25.

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.
