Technical FAQs 4

What happens if a PV inverter reaches a maximum current limit?

The inverter’s DC input current should always stay within its maximum limit. If the PV module’s output current exceeds this limit, it may lead to current-limited operation and potential inverter damage, reducing power generation efficiency and return on investment.

What is a maximum input current in a PV inverter?

1. Maximum Input Current Definition: The maximum operating current allowed to pass through the PV side of an inverter. The input current is especially critical in scenarios with high peak power currents, such as those involving thin-film PV modules.

How many kW can a PV inverter output?

Export to Grid: Up to 4kW can be sent back to the grid because of the export limit. This means: The inverter can handle this 5kW AC output perfectly. However, the PV array is generating 10kW, so we have:

How does a PV inverter reduce power output?

By reducing the current, it effectively reduces the power output. Maximum Power Point Tracking (MPPT): Normally, the inverter uses MPPT to maximise the power output from your PV array. During curtailment, the MPPT algorithm adjusts to a point where the power output is reduced to match the inverter’s capacity.
