FAQS 4

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.

What is a maximum input current in a PV inverter?

1. Maximum Input Current Definition: The maximum operating current allowed to pass through the PV side of an inverter. The input current is especially critical in scenarios with high peak power currents, such as those involving thin-film PV modules.

How do you calculate the efficiency of a PV inverter?

It depends mainly on the power and can also be a function of the input voltage. In PVsyst there are 4 ways of defining the efficiency of inverters : from a set of 3 efficiency curves eff = f (Power, input voltage), all of them automatically built from the Maximum, EURO or CEC efficiencies and Pthresh.

What happens if a PV inverter reaches a maximum current limit?

The inverter’s DC input current should always stay within its maximum limit. If the PV module’s output current exceeds this limit, it may lead to current-limited operation and potential inverter damage, reducing power generation efficiency and return on investment.
