6 FAQs about [Limit PV inverter power]

How to improve PV inverter lifetime?

In response to this problem, the literature proposed a novel control strategy to limit the power generation, thereby improving the PV inverter lifetime. For a specific photovoltaic inverter system, there should be an optimal PV system capacity ratio and power limit value, taking into account inverter damage and increasing power generation.

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.

How much damage does a photovoltaic inverter cause?

When the optimal PV system capacity ratio and power limit value are taken, the annual damage of the IGBT in the photovoltaic inverter is 0.847% and the net increase of power generation is 8.31%, realizing the increase of photovoltaic power generation while the annual damage of IGBT and power generation loss due to power limit is relatively low.

Can a control strategy improve a photovoltaic inverter lifetime?

However, during the peak period, the PV output power is large, thus causing damage to the photovoltaic inverter. In response to this problem, the literature proposed a novel control strategy to limit the power generation, thereby improving the PV inverter lifetime.

How to provide voltage support in PV inverter?

To provide voltage support at the PCC, reactive power is injected into the grid under fault conditions as per the specified grid codes. As previously discussed, the simultaneous injection of peak active power from PVs and reactive power into the grid for voltage support can trigger the over current protection mechanism in PV inverter.

What is the use of bus voltage in a photovoltaic inverter?

The increase in bus voltage is used as the control signal of the PV output current to reduce the photovoltaic output current, such that the PV output power is reduced from 3000 W to the inverter power limit value of 1500 W, which meets the requirements of the inverter output power limit.
