4 FAQs about [PV string inverter selection]

Why is string sizing important in photovoltaic system design?

In photovoltaic (PV) system design, string sizing is one of the most critical steps to ensure efficiency, safety, and system longevity. Incorrect sizing can lead to inverter faults, reduced energy yield, or even equipment damage. By understanding the key electrical and environmental parameters, you can design strings that work optimally year-round.

What to check before string sizing a solar inverter?

Before string sizing we will need to check the inverter limits and peak performance ranges. Example inverter data sheet Max. PV Power: be sure that the total number of modules are below the inverter's maximum. Max. DC Voltage: be sure that the total modules in series are below, in this case, 600 V total.

How many strings can be connected to a solar inverter?

Here are the results we calculated: This inverter has 2 MPPT trackers, so a total of 2 strings can be connected to the inverter. We know that there can only be 13 modules maximum installed. We can have one MPPT with 6 modules in a string and the other at 7 modules in a string. Check out UpTop Solar String Sizing Tool that does this for you!

How to choose a solar inverter?

Max. PV Power: be sure that the total number of modules are below the inverter's maximum. Max. DC Voltage: be sure that the total modules in series are below, in this case, 600 V total. MPPT operating voltage range / Start Voltage: be sure the minimum module voltage is above the operating MPPT lower range of the start voltage, whichever is higher.
