Jason,
How do you AC couple some microinverters to cover the decrease in
performance in an off grid system, especially with older
equipment, such as an SW4024?
Thanks, Allan

I totally agree - old mods are usually not worth
messing with at today's PV prices. In some cases it might be
best to downsize the system and then AC couple some
microinverters to cover the decrease in performance, or just
replace the entire array if there are enough problems. There is
a used market for smaller PV mods on Craigslist.
Back when I was installing Astropower 110W modules on
single voltage Xantrex C40's, I never thought we'd be using
anything but 12V nominal PV mods. Little did I know...
Off-grid is really tough in these retrofit situations, but
this applies to failed/broken mods on grid-tie systems as
well. That's where I can make a good case for microinverters.
