Dave Tedeyan,
u are adding Enphase to
an existing Sunpower system, you might be able to get one of the specially
programmed Gateways from the beginning. Those will be able to monitor both
the Enphase and the Sunpower equipment.

Hi All,
I talked to Enphase recently about this. They will be providing warranty
support at least for Sunpower's microinverters. They do not know how long
Sunpower's monitoring will continue to work. But they have figured out a
way to use their Gateway to monitor Sunpower's microinverters, even th

I am not sure if this is the same issue, but I have seen a lot of arc fault
issues with the E20-327 modules paired with SMA inverters. Every system
that we have done repairs on have had the Yukita junction boxes, and there
were a handful of failed solder joints on the diodes in the junction b

This winter we were fixing up a system with a fronius primo inverter and
adding rapid shutdown. Fronius very much recommended against using Tigo.

, its not
a big deal, since these batteries are just for short term backup, so if the
inverter just cycle off and on when the batteries are mostly full, that
will be okay. But it would be nice if I can set up the frequency control.

Drake,
I believe that is for a single phase 2 wire output only. I am assuming one
hot and one neutral for the inverter output in this case. I would think
most *grid tied* inverters fall under 705.95B, where the neutral is only a
voltage sense and can be sized as small as the equipment ground.

Hi Mac,
Might I ask what modules these are connected to? There is some history here
with Sunpower modules (and possibly other high power, high voltage
modules). In these cases the issue is the module. If that's the case I can
provide some more detail about it.
As for remote resetting, it is actua
whole controller.
Thanks!
-Dave

Hi Jason,
I recently did a microinverter swap of the old D380's to 54 of the IQ7
190's. Once it was commissioned I started seeing random MI's drop out, but
not always the same ones. I am pretty sure that this was due to
overvoltage. I measured the line voltage at 255v with the system turned
off.

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

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!

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

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.
Cheers,
Dave

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.
