WARNING!
Make sure that you use suitable conductors for both the AC and DC wiring. The conductors must be
adequatelysizedandofcorrecttemperatureratingandsunlightresistantifneeded.Useonly#10AWGto
#6 AWG, 90C (194F) stranded or solid copper wire (but not fine‐
stranded wire) for all AC and DC wiring

WARNING!
PV arrays will be energized when exposed to light.Cover the arrays with opaque materials during
installationandwiring,and/orkeepmoduleleadsdisconnected.

set
for the connection configurations with neutral, it can automatically detect the utility voltage and adjust the output AC
