6 FAQs about [Large PV Inverter Parameters]

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.

How do I choose a PV inverter?

Based on the available area, efficiency of PV modules used, array layout and budget. Selecting one or more inverters with a combined rated power output 80% to 90% of the array maximum power rating at STC. Inverter string sizing determines the specific number of series-connected modules permitted in each source circuit to meet voltage requirements.

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 an inverter for a grid connected PV system?

When specifying an inverter, it is necessary to consider requirements of both the DC input and the AC output. For a grid connected PV system, the DC input power rating of the inverter should be selected to match the PV panel or array.

Which inverter is best for solar PV system?

To handle high/medium voltage and/or power solar PV system MLIs would be the best choice. Two-stage inverters or single-stage inverters with medium power handling capability are best suited for string configuration. The multi-string concept seems to be more apparent if several strings are to be connected to the grid.

How efficient is a PV inverter?

Modern inverters commonly used in PV power systems have peak efficiencies of 92-94%, but these again are measured under well-controlled factory conditions. Actual field conditions usually result in overall DC – to - AC conversion efficiencies of about 88-92%. 4.1.2. Duty Rating
