I posted this earlier, but will just start over with some added facts
Our system will be a 13.2 KW grid tie, using a Fronius 11.4 Inverter. The panels will be mounted on a shed. The single phase AC 220v run from the Inverter to the distribution box will be 275 feet (100' inside the shed, then another 175 feet underground to dist. box). This will be Aluminum wiring
Again, using a Fronius Primo 11.4kw Inverter, specs are below:
I will be using 4 - 8 panel arrays (400w Heliene). The Spec for each Panel is below:
Peak rated Power: 400w
Max Power Voltage: 40.70
Max Power Amps: 9.83
Open Circuit Voltage: 49.58
Short Circuit Current: 10.35
Module Efficiency %: 20.13
So, trying to calculate the wire gauge size for a 275' run from Inverter to Main Breaker box. Which of the above data would I add to the online calculator to determine gauge needed?
