Solar container inverter parameter selection requirements

What are the parameters of a PV inverter?

Aside from the operating voltage range, another main parameter is the start-up voltage. It is the lowest acceptable voltage that is needed for the inverter to kick on. Each inverter has a minimum input voltage value that cannot trigger the inverter to operate if the PV voltage is lower than what is listed in the specification sheet.

What parameters should be considered when stringing an inverter and PV array?

Both the maximum voltage value and operating voltage range of an inverter are two main parameters that should be taken into account when stringing the inverter and PV array. PV designers should choose the PV array maximum voltage in order not to exceed the maximum input voltage of the inverter.

How to choose a PV array maximum voltage?

PV designers should choose the PV array maximum voltage in order not to exceed the maximum input voltage of the inverter. At the same time, PV array voltage should operate within the input voltage range on the inverter to ensure that the inverter functions properly.

How to configure a PV string?

In the PV system, the PV string configuration must meet the inverter configuration requirements for different inverters to achieve optimal energy yields. This configuration solution lists some common configuration principles for reference. 1. For the same MPPT input, configure PV modules of the same model, direction, and quantity.

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 are inverter specifications?

Specifications provide the values of operating parameters for a given inverter. Common specifications are discussed below. Some or all of the specifications usually appear on the inverter data sheet. Maximum AC output power This is the maximum power the inverter can supply to a load on a steady basis at a specified output voltage.
