Lower than the inverter operating voltage

What are the parameters of a PV inverter?

Aside from the operating voltage range, another main parameter is the start-up voltage. It is the lowest acceptable voltage that is needed for the inverter to kick on. Each inverter has a minimum input voltage value that cannot trigger the inverter to operate if the PV voltage is lower than what is listed in the specification sheet.

Why do solar inverters have a low voltage?

However, they are designed to allow lower voltage once they are in “ON” mode, and that is what we mean by the minimum operating voltage range. As power is processed and converted from one shape to another, the solar inverters are expected to perform these tasks with the highest possible efficiency.

How does an inverter lose power?

However there are limits in power, voltage and current. When attaining one of these limits, the inverter will clip the operating point on the intersection of the I/V curve and this limit. The power difference between the MPP of the arrays' I/V curve and the effective power of this operating point on the limit curves is accounted as inverter loss:

Can an inverter be damaged if the maximum input voltage is exceeded?

Although the inverter can be damaged if the maximum input voltage is exceeded, exceeding the maximum MPP voltage is, by contrast, nonhazardous. Similar to the case of the minimum input voltage not being reached, the operating point of the PV array shifts itself in relation to the MPP, resulting in a lower loss in yield.
