[RE-wrenches] Sol-Ark arc fault issues

[Eric Smiley via RE-wrenches]

A general question for those who have installed Sol-Ark.
We have a handful of systems that have consistently displayed arc-faults
that, as best as we can determine, are false positives. Is this something
others have experienced? We are trying to determine if this is a general
problem with Sol-Ark or if we are having poor luck.
Our other string inverter systems are not displaying this problem, which
leads us to believe it isn't due to installer error.

Re: [RE-wrenches] Magnum inverter/generator integration problems

[Eric Smiley via RE-wrenches]

Also check bonding and ground loops (e.g. genny neutral bonded and also
bonded at main panel). This can cause voltage to bounce around and the
inverter won't sync.

Re: [RE-wrenches] GT inverter for SWWP turbine

[Eric Smiley via RE-wrenches]

Skybox is discontinued and tech support is limited. There are still
significant software issues with them that make them unreliable for battery
back-up. We are in the process of replacing the 3 Skyboxes we wish we had
never installed.

[RE-wrenches] Old Birdhouse systems

[Eric Smiley via RE-wrenches]

We have some older systems that used the MidNite Disco Combiners and
Birdhouse.
We have to install a new Rapid Shutdown system since these can't be
replaced.

My question is, can I quickly/easily disable the Rapid Shutdown in the
Combiner and still use it as a combiner?

What is the signal in the CAT5 cable anyway?

Re: [RE-wrenches] 3 phase off-grid UL listed

[Eric Smiley via RE-wrenches]

I've worked with a few larger 3-phase Conext XW systems - 3 inverters and 6
inverters.
The inverters' output capabilities are slightly reduced since they have to
be converted to 120 V, effectively doubling the output current. Also,they
required an external transfer switch. Even with 3 inverters configured for
3-phase, I would recommend an external transfer. The relays have a habit of
welding.
Once they were configured properly, there was no problem starting large
HVAC loads and even large single phase loads were OK.

Re: [RE-wrenches] AC Coupling Standard?

[Eric Smiley via RE-wrenches]

Utilities have used and continue to use this method of control for their
own generators, except they refer to it as Droop Control. In addition to
Frequency/Watt response Voltage/VAR response is also used.
https://en.wikipedia.org/wiki/Droop_speed_control

Building inverters that mimic the behaviour of spinning generators is a
great development as some jurisdictions now require, for example,
ride-through capability when brown-outs occur, rather than the older
requirement for inverters to simply turn off when voltage or frequency
dropped below certain limits, which just exacerbated brown-outs.
Essentially an inverter can be programmed to have "inertia" just like a big
spinning generator.
Larger grid-interactive inverters have done this for a while, with very
complex settings, but we are now seeing smaller residential and
commercial inverters with similar capabilities.
This industry keeps evolving and improving, which is great for keeping us
on our toes and I find it very exciting.

[RE-wrenches] XWPro produces noise at low (<50 W Power)

[Eric Smiley via RE-wrenches]

The inverter produces acceptable noise under no-load and at loads above 50
W or so.
The noise (humming/buzzing) increases drastically at low power. So,
essentially it makes a lot of noise at night.
Has anyone else encountered this? We suspect it is the transformer
vibrating - some kind of resonance with the inverter enclosure. But it's
the first time we have encountered this.

Re: [RE-wrenches] XWPro produces noise at low (<50 W Power)

[Eric Smiley via RE-wrenches]

Thanks. That was the feedback we already received. I think it is SOP for
Schneider to tell you to reinstall firmware and reset to factory - no
matter what the problem.
Fortunately, we have to go back to do some more wor - they are finally
receiving their generator. That will give us a chance to recommission the
system.

Re: [RE-wrenches] Lithium battery recommendation

Keep in mind the Fortress eVault is a 500 lb beast. Our installers
complained about it and we've moved to smaller, rack-mount units and are

Re: [RE-wrenches] Fronius USA available 2023 & 2024 ?

[Eric Smiley via RE-wrenches]

Interesting. Fronius has a strong presence in Canada with good tech
support. We also have a very low failure rate - can't remember the last
time we replaced one. There were some supply issues earlier this year but
we are receiving inverters and parts. They also have a good rep for low
failure and good service in Australia and Europe. Not sure why the US gets
short shrift.

Re: [RE-wrenches] Off Grid, Cloudy Days, Solar Tilt Question

[Eric Smiley via RE-wrenches]

It is difficult to quantify but this was pointed out to me years ago by a
long-time off-grid installer, who also lives off grid on Vancouver Island
where weeks of solid cloud isn't unusual. We never tilt to latitude + 10 to
15 for off-grid, as many textbooks recommend.
Latitude works quite well. When I've tried modelling it, January is the
only month that seems to outperform when tilted at less than latitude,
which is often our cloudiest month. We also have a lot of conifers here so
tilting to 60 degrees often means the modules are facing the trees anyway.
Fortunately we don't get much snow so a shallow tilt is OK.

Re: [RE-wrenches] Grid Tied Inverter back feed to Generator

[Eric Smiley via RE-wrenches]

 We were called to repair a system where this happened.
All the micro inverters were fried and so was the generator. It caused a
voltage rise that the monitoring system recorded at 348 V before it went
down, when the PV ran the generator as a motor.

Re: [RE-wrenches] Fortress

[Eric Smiley via RE-wrenches]

The BMS in the eVault Classic has been a headache.
Fortunately, we were able to convince Fortress to let us proactively
replace the BMS in some of our systems - especially the remote off-grid
systems. We are still having problems with weird SOC readings on many of
the batteries. Apparently the SOC reading can get stuck at 100% and
Fortress is aware of the bug. It is frustrating because the owners rely on
the SOC reading rather than voltage.
This experience did convince me that Li-Ion in off-grid applications is not
a reliable solution unless there are multiple independent batteries with
their own BMS. The battery itself may be robust (how long have these
actually been in the field in real-world applications) but the BMS is a
complicated piece of electronics on which the entire system is dependent.
Li-Ion violates the KISS principle. So we talk our off-grid clients out of
using Li-Ion.
IMHO relying on firmware and circuit boards to keep your system running and
protect it from catastrophic failure is not sustainable.

Re: [RE-wrenches] Sol-Ark 15k solar panel frame grounding

[Eric Smiley via RE-wrenches]

SolArk arrays are ungrounded. However, because they are transformerless,
when the inverter is operating, there is a reference to ground on the DC
side via the AC side neutral bond to ground. So, a ground fault on the AC
side will also cause a GF error.

Many transformerless interactive inverters are using Isolation Resistance
testing to detect ground fault, rather than measuring current. Sol-Ark
doesn't have any literature to say what method of GF detection they use,
but it is unlikely there is a reference to ground via the GF detection
method.

In any case, they aren't solidly grounded, and none of the DC conductors
should be white or grey, they can both be hot with respect to ground.

Re: [RE-wrenches] Lead acid batteries taking too much current

[Eric Smiley via RE-wrenches]

Our company does not pair any lead acid with a Sol-Ark. Our opinion is that
the unit is designed for Li-Ion and that is what should be used. In much
the same way that some legacy off-grid products don't play nicely with
Li-Ion, we stick with combinations that don't require specialized
programming work-arounds that aren't in the manufacturer's manual.

Interesting aside, I recently had to service a very old Trace DR system
which the client had upgraded to Can-Bat Li-Ion. The service call had to do
with the generator but I checked the batteries and charging history. It
looks like the DR is so dumb it, it works just fine with the BMS keeping an
eye on things.

Re: [RE-wrenches] AGM battery recommendations

[Eric Smiley via RE-wrenches]

The disparity in cycle life can sometimes be due to different test
standards for cycle life evaluation.
I'm familiar with three standards that are commonly used by manufacturers:

   1. IEC 61427
   2. IEC 60896-2
   3. BCIS-06

The IEC 61427 standard is specifically for Solar PV applications.

Re: [RE-wrenches] Outback Optics RE is down again

[Eric Smiley via RE-wrenches]

Same here. I had to defeat my security to access the site. This is
worrisome since some of our sites are fly-in or boat access only.
In addition, all Outback products lost their CSA listing when they were
bought. So we cannot install any of their products - if we could get them -
under a permit. We are crossing our fingers we don't have any failures.
