FAQS about Calculation of photovoltaic inverter input voltage

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 do you calculate a volt increase in an inverter?

This is how many volts each module will increase due to record-low temperatures. Add the voltage increase to the Module VOC. Then divide the inverter maximum input voltage by that number. This will give you the maximum number of modules that can be wired in a series string per that inverter and specific location.

How do you calculate a voltage rating for an inverter?

Simply divide the inverter’s maximum system voltage rating by the open circuit voltage (Voc) of the module used and you’re good. Well, that does get you in the ballpark, however, you could be at risk of over-sizing or under-sizing the number of modules in a string depending on where you are located in the world.

How do I calculate PV string size & voltage drop?

The easiest and fastest way to calculate PV string size and voltage drop is to use the Mayfield Design Tool. Our web-based calculator has data for hundreds of PV modules, inverters, and locations so you don’t have to look up datasheets nor do manual calculations. You can access the Mayfield Design Tool for free on our website here.

How do you calculate inverter input current?

The inverter input current is calculated by Ohm’s law (I=P/V) and is 5.76 A (4900W/850V = 5.76 A). The dc source circuit design current is 15 Amps continuous which is the output current limit of the power optimizer.

How do I Optimize my inverter's output voltage?

But truly optimizing the string’s output means choosing a string length that lands within a more narrow optimal voltage range: the “rated MPP (maximum power point) voltage range.” Input voltages within this range allow the inverter to output at its rated value.
