Pv wire gauge

[Mermaid007]

Hi I have a eg4 6000xp and I’m connecting five 400 W solar panels in series and what can I get away with on the PV wire as in the gauge size for this set up, i’m thinking 40 or 50 feet from the panels to the inverter, I have a picture of one of the panels amp and watts rating. Thanks for your help in advance.

There are several voltage/ current/awg charts online but 10awg would be perfect.

Personally I wouldn't feel comfortable going smaller diameter both for safety and adding more in the future.

Southwire says minimum 14awg for 250v DC and 11 amps. That is if some voltage drop is acceptable. I think that's way too small.

10awg, 12awg at the least.
