Technical FAQs 4

Can an inverter output more than rated AC power?

Inverters will generally never output more than their max-rated AC power. During times when the DC input power is too high, the inverter will raise the operating voltage of the modules to pull the array off of its max power point and reduce the DC power. Why a 20% DC/AC ratio results in minimal clipping losses

What happens if a power inverter's DC/AC ratio is not large?

The following illustration shows what happens when the power inverter’s DC/AC ratio is not large enough to process the higher power output of mid-day. The power lost due to a limiting inverter AC output rating is called inverter clipping (also known as power limiting).

What is DC to AC inverter ratio?

The DC to AC inverter ratio (also known as the Inverter Load Ratio, or “ILR”) is an important parameter when designing a solar project.

What happens if an inverter is in over power mode?

Generally, when an inverter is in over-power mode, it simply means that it will sacrifice the excess power. So even when the actual DC power is 10% over the max AC power, the losses are just 10% for that time.
