6 FAQs about [Photovoltaic inverter capacity increase meter]

What are the advantages of a PV inverter?

The extraction of maximum power from all of the PV strings during partial shading and mismatch between PV panels. Ability to extract power from PV strings during sunrise/sunset or cloudy sky with low irradiation. Higher modularity compared to the single-stage power conversion with a central inverter.

Can an SMA inverter oversize a PV array?

In this example, we need 60kVA of inverter capacity, but only generate 49kW of active power. This means we can oversize SMA inverters by approximately 20% compared to the size of the PV array. SMA inverters can generate reactive power without using any active power.

How does a SMA inverter improve grid quality?

SMA inverters can help improve a site’s power factor through the use of built-in grid support functionality, such as a dynamic cos (φ) function. This improvement can help reduce grid quality supply charges a customer might incur from their electricity provider.

Can SMA inverters generate reactive power without using active power?

SMA inverters have the capability to generate reactive power without using any active power, which is referred to as Q @ Night within SMA. By oversizing inverters, you can secure reserve reactive power capacity without sacrificing active power generation.

Can an SMA inverter reduce electricity bill?

An SMA inverter can help you save more money by reducing the grid quality charge component of your electricity bill through its built-in grid support functionality. By feeding reactive power as well as active power, it corrects a bad power factor.

What is inverter clipping?

Inverter clipping, or “inverter saturation,” occurs when DC power from a PV array exceeds an inverter’s maximum input rating. The inverter may adjust the DC voltage to reduce input power, increasing voltage and reducing DC current. Alternatively, the inverter may restrict or throttle the inverter’s AC output.
