I'm with you guys and we actually had a bad transformer bushing at this
site initially which was causing exactly that issue. The site still runs
high (498-508Vac nominal) but is well below the 528V default upper limit of
the TLs, and the shut-offs are not correlated with higher AC voltages.

Concur with Sandra completely.
All of my clients are having no
problems with Insight2 as far as what Howie wrote. It has been very
reliable for about a year now.
The remote programming with Insight2 has
had a few issues but it is on the sched to be fixed. Many are working fine
but a few are
It sure looks like it could be an AC voltage issue. Around here the utility
voltage is often high in the morning and then gets dragged down when loads
in the neighborhood spike from air conditioning (yes, even in winter here
in Florida). We see drop-outs (with other brand inverters) in the
Andrew, I've seen this in multiple inverter systems when the AC voltage
gets pushed outside the upper limit by the inverter output currents. One
or two inverters will cycle on-off, those with the lowest setting or
tolerance. Cause can be (1) high AC voltage from the utility to start
with, and/or

What is the AC Voltage when this occurs, to much VAC will shut down the
inverter. It also looks like you are clipping all the inverters during the
mid day, is due to low temps or does this always happen. What is the DC
MPPT voltage, is it at the upper limit.

Wrenches,
I have a couple of Solectria 36TLs at a small community solar site in CO
that shut themselves down occasionally for what appears to be no reason.

Voltages and frequency are normal, firmware is updated, IR scan shows
nothing irregular, and the other 2 inverters at
Howie,
The “no communication” issues on Insight2 was solved when we update to Gateway
firmware 1.05, and in parallel, we updated the Insight2 platform.
The issue Dave is mentioning is on making programming changes.
If you still have a site (with the latest firmware on the Gateway) but still no
Dave,
Do these problems encompass having sites that previously were configured
and operating on Insight2, but for at least the last month or 2 have shown
up on the home page, but either show no connectivity or no devices? This
has been my experience and it is a major issue since I sold my clients
Last week I was called to examine a solar power system installed by an
Idaho electrical contractor. According to the owner of this system, this
contractor has built several similar systems in the area.
The owner's complaint was that the AGM batteries kept failing. The work
was done without
Hi Wrenches,
Some who have been experiencing the inability to remotely
control with Insight2 should know that a fix is on it's way. I got this
yesterday. There was also a Gateway and mobile App update on the Schneider
site. You may want to try it again soon and let me know please. Thx!
