FAQS 4

What is the minimum string size of a PV inverter?

The minimum string size, then, is 15 modules. The maximum string size is the maximum number of PV modules that can be connected in series and maintain a voltage below the maximum allowed input voltage of the inverter. The Module Voc_max is calculated using the coldest temperature when the modules produce the highest expected voltage.

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 does a string solar inverter work?

Example panel data sheet All modern string solar inverters have one or more MPPTs (maximum power point trackers) to track the string voltage and lock onto the optimum voltage, which in turn produces the maximum power. Throughout the day, many variables will influence the string voltage, including; weather, shading and temperature.

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.
