Connection between N and PE during inverter operation. - The ground relay is useful when an earth-leakage circuit-breaker is part of the installation.

How many volts is a string inverter?

String voltage = 37.6V * 19 panels = 714.4V This is higher than the inverter’s minimum DC input voltage (200V), so it’s fine. The total string current is the same as the Isc of one panel, 9.4A, which does not exceed the inverter’s maximum DC input current (25A).

How do you calculate a string size for an inverter?

Calculate the Maximum String Size Take your inverter’s maximum DC input voltage. Divide it by your adjusted Voc. This gives you the maximum number of panels you can have in a string. For instance, if your inverter’s max input is 1000V: You can’t have a part of a panel, so round down to the nearest whole panel.
