6 FAQs about [Reducing the input voltage of the inverter]

How do inverters reduce DC power?

In response to this condition, the inverter typically adjusts DC voltage to reduce the DC power. This is done by increasing voltage above the MPP voltage, thus reducing DC current. Most, but not all inverters self-limit.

How to control the output voltage of an inverter?

When the available input voltage source is dc, the inverter’s input voltage can be controlled by using a chopper. The block diagram for controlling the output voltage of the inverter when the input voltage available is constant is of constant DC type is shown below.

Why does my inverter go into 'voltage-dependent power reduction' mode?

Why your inverter goes into 'voltage-dependent power reduction' mode In marginal cases your inverter may not trip off, but may reduce its power output instead as a way to cope with grid voltages that are a little too high. When your inverter reduces its power due to high grid voltages it is in what's called "Volt-watt response mode".

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.

What is inverter saturation?

Inverter saturation, commonly referred to as “clipping”, occurs when the DC power from the PV array exceeds the maximum input level for the inverter. In response to this condition, the inverter typically adjusts DC voltage to reduce the DC power. This is done by increasing voltage above the MPP voltage, thus reducing DC current.

What happens if my inverter reduces its power?

When your inverter reduces its power due to high grid voltages it is in what's called "Volt-watt response mode". This feature is recommended in the latest version of Australian Standard AS4777.2 - and if your inverter has the feature, the standard mandates that it must be activated. I knocked out this sketch to show what happens.
