Grid power limitation

For maximizing the annual yield, people often install an over-sized PV system (high DC:AC ratio), and accept some energy loss during the best hours of the year (peak-shaving). In practice, the power limitation cannot be performed at the injection level, since there is no device able to "absorb" any excess power (meaning to dissipate it as heat).

6 FAQs about [The maximum excess power of photovoltaic inverter]

What is the maximum output of a solar inverter?

Maximum output is what your inverter will output on a perfect day (within tolerance). Most 10kW inverters have a maximum output of 10,000W. If you oversize your solar panel array, it’s not unusual that a 8000w inverter would reach 10,100W or even 10,200W. Nominal output – for all intents and purposes – is a joke.

Do PV inverters oversize?

PV inverters are designed so that the generated module output power does not exceed the rated maximum inverter AC power. Oversizing implies having more DC power than AC power. This increases power output in low light conditions. You can install a smaller inverter for a given DC array size, or you can install more PV modules for a given inverter.

What happens if a solar inverter exceeds a power rating?

Exceeding this power rating can lead to overloading the inverter and potential system malfunctions or damage. To avoid overloading your solar inverter, ensure that the total power output of your solar panels does not exceed the inverter’s capacity.

How does a PV inverter reduce power output?

By reducing the current, it effectively reduces the power output. Maximum Power Point Tracking (MPPT): Normally, the inverter uses MPPT to maximise the power output from your PV array. During curtailment, the MPPT algorithm adjusts to a point where the power output is reduced to match the inverter’s capacity.

How do I avoid overloading my solar inverter?

To avoid overloading your solar inverter, ensure that the total power output of your solar panels does not exceed the inverter’s capacity. This can be determined by calculating the maximum power output of your panels under normal operating conditions and comparing it to the inverter’s power rating.

What happens if a PV inverter is overloaded?

Overloading an inverter can help to increase the energy yield of a PV system by allowing more DC power to be converted into AC power. However, overloading an inverter can also cause clipping, which occurs when the inverter cannot convert all the DC power into AC power. Shade is another factor that can affect the performance of PV systems.
