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 happens if a grid-tied inverter exceeds a threshold?

If the grid voltage or grid frequency exceeds the thresholds specified by the grid operator, the grid-tied inverters must stop to feed in alternating current and disconnect from the utility grid in accordance with local standards and directives. Inverters are also able to modulate their output power to support the utility grid interactively.

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.

What happens if an inverter exceeds the maximum short-circuit current?

If this current exceeds the maximum short-circuit current that the inverter can handle, the inverter may suffer damage. The maximum short-circuit current that an inverter can handle is primarily determined by factors such as design parameters, internal circuit structure, and component durability.
