I would certainly agree with you all that AC coupled for off-grid is not
the best design choice. But just for clarification, this is a grid-tied
system where there is already an Enphase M215 system and a whole house
generator set up.

Hi Dave,
You did get the Square D part right. See the Schneider website, which shows
that it is 600V DC and does have an off in the middle.

On
Kirk,
Could there be a loose wire connection to the breaker? That could cause it
to heat up an trip sooner than it otherwise would.

the
inverter when the transfer switch loses the 240V signal. My plan was to
rewire that start signal to the Sol-Ark inverter, but keep the transfer
switch as the main service point to prevent any kind of backfeeding to the
grid.

Dave,
This is for a boat that will stay mostly on the finger lakes and in the
Erie Canal system in upstate NY. Definitely not an ocean boat. But the plan
is to convert it to a full time residence, potentially in the winter as
well.

Hi Chris,
I also am curious of others experiences. I've got one system with SMA and
the TS4-R-F. No problems, but it's only 6 months old. I hear that SMA now
recommends the ones made by JMS, but it looks like essentially the same
thing.
Cheers,
Dave

Hi All,
I am looking for recommendations for a solar racking system that can be put
on a flat commercial roof where the point loads can span 12-13" east/west.
I am imagining a system built up almost like a ground mount. Does anyone
have manufacturer suggestions?
Thanks!
some kind of fault in the inverter itself
that
occasionally induces extra current? Is there any way to tweak the settings
so that it
actually produces a bit more than 11.4kw? I appreciate your thoughts.
Cheers,
Dave

ystem at the same site, so the original
installers' wire pulling technique is certainly suspect.

Not being my original install, I am not sure if this was an issue before. I
wonder if somehow the IQ series could be more sensitive to overvoltage? But
anyway, try checking voltage...

It is always the left fuse! Thanks all for the pointers. I'll double check
the monitoring, but am thinking that I will be replacing the switch with a
SQD, and replacing the taps and AC wires as well while I'm at it.
