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.
What is a string inverter system?
A string inverter system aggregates the power output of groups of solar panels in your system into "strings." Multiple strings of panels then connect to a single inverter where electricity is converted from DC to AC electricity.
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.
