Port Vila PV inverter parameters

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 to choose a PV module?

Reminder: When selecting PV modules, ensure that their short-circuit current does not exceed the inverter’s maximum short-circuit current rating. Before designing the system, adjust the number or configuration of PV modules according to the rated short-circuit current of the PV panels and the inverter’s maximum short-circuit current.

How to choose a PV inverter?

When selecting an inverter, it is essential to ensure that its maximum DC current specification meets the requirements of thin-film modules. The current of each MPPT-connected PV string should remain below the inverter’s DC current limit to prevent overcurrent damage.

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.
