Why do photovoltaic converters have a 1:1 capacity ratio?

From the analysis of the above influencing factors, under the traditional 1:1 capacity ratio design, the maximum power generation of the photovoltaic system is lower than its installed capacity, and a certain ratio of component over-configuration can make up for the capacity loss of the inverter and improve the utilization rate of the converter.

Can the over ratio of modules bring higher power generation?

Should a 9 kW PV array be paired with an AC inverter?

Thus a 9 kW PV array paired with a 7.6 kW AC inverter would have an ideal DC/AC ratio with minimal power loss. When the DC/AC ratio of a solar system is too high, the likelihood of the PV array producing more power than the inverter can handle is increases.

Why does PV module output rarely produce power at rated output?

This common question has a simple answer. In real world conditions, PV module output rarely produces power at the rated output due to thermal losses. PV module power is a product of DC current and DC voltage. In a PV module, the DC voltage is a function of PV module cell temperature. That is, DC voltage goes down as cell temperature goes up.

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 nameplate rating of a solar inverter?

Thus the nameplate rating of the inverter is its capacity to process the power of the PV array. For example, a 7.6 kW inverter can produce an output of up to 7.6 kW AC. A 9 kW DC solar array rarely produces this much power.
