I prefer to use the Flexware for my Sunny Island Installs the wiring
configuration is very similar to that of the vfx series inverters and wires
up very similar.
On the three inverter SI system is this a hybrid with generator? If so how
did they configure the DigIn for monitoring between gen and grid mode?
If you want to see a pic I can send you one

Hello Wrenches,
Here is a solar repair puzzle.
I am debugging a faulty and now partially non-functional grid-tie job in
Southern California installed by another (non-cooperative) contractor. One
of two inverter's has failed (2 months post warranty) and I am trying to
find a solution for the homeowner that doesn't involve a complete system
re-install and meter main panel upgrade. Here are the repair issues:
#1) ARRAY DESIGN FLAW: There are 2 inverters with single MPPTs that each
serve arrays with panels facing in two directions (90 degrees azimuth apart)
in the same single source circuit string. Details: 30 KC130GT panels
facing East. 18 KC130GT Panels facing South. Each 3000 watt inverter has 1
string of 24 Panels?mixed and matched. (and here's the kicker---10 separate
physical sub-arrays?really) (Note: module and array wiring not "PV" rated)
#2) INVERTER FAILURE. One of the two inverters (A piece of crap Xantrex
GT3.0 that was field-serviced for the bad capacitor in 2011) is kaput.
#3) GROUND FAULTS: Wet weather ground faulting on PV source circuit for
failed 3K inverter (fuses blown 3 times.) No significant voltage to ground
when dry. Don't yet have a wet wire voltage reading to find fault.
#4) CODE VIOLATIONS.
A) Meter Main Buss Overload. 100 amp rated panel. 100 amp MCB. 40 amp
solar breaker. Even better?a famously flammable Zinsco buss and breakers.
28.4 amps max combined continuous inverter current. (not likely due to the
different azimuths of the array, but?you know?way over NEC 690.64.B.2).
B) Inadequate GEC?undersized and improperly spliced all over the place.
Thus: Is this poor old lady just hosed? Any clever ideas to save her from
a massive repair and meter main upgrade? She is looking at 10k+ fix.
Second story steep roof? I'm stumped.
Best regards,
Abe

Hi All,
Correction: Another Wrench member contacted me off-list and noticed that we
have a class RK5 in one photo and a T in the other photo. This opens up the
question of whether one or both are correct or incorrect. I think both are
rated for 20k AIC for DC voltage but I'll have to look through my order
records to be certain. The R is slow acting and the T is fast acting.
Best,
August

Hi Dan,
I've been wondering the same think. We've been fusing with a class T in the
battery box and grounding the negative side of the batteries. See attached
pics. Do you feel that the fuses should be outside of the battery box?

Does anyone have any elegant solutions to this? It's really time consuming
and ugly to run big parallel battery string wires *out* of the battery
enclosure to class T fuses, then back into the battery box. It looks very
ugly and DIY, and in conduit adds a few hundred to the install cost just
for labor. The Class T fuses and blocks themselves are not particularly
expensive.
I have been recommending parallel fusing on battery banks of 2x8 L16s and
over now, after a nearly tragic incident with a bad cell that shorted. The
(perfectly legal) wooden battery box made the fire much worse. A pet peeve
of mine.

Friends:
I am reworking an installation with 3 Sunny Island inverters. The battery
leads have no disconnecting means or OCP. I have been looking for sensible
hardware to provide this and I have found some options. I am interested in
any input on these or ideas I have not discovered.
1. SMA BATFUSE. I am having trouble deciding which one is right for a
3 SI install.
a. The B.003 appears to have fuse positions for the positive and the
negative leads. I am fairly darn certain I don't want fuses in the negative
leads of a negative bonded system, and although this is my first SI install,
I am pretty sure this is negative bonded. Am I missing something here?
b. The B.001 has only positions for two fuses as far as I can see from
the manual.
c. So it looks like neither will work for me. Does anyone have any
experience and/or wisdom here?
2. Midnite Solar E-panels:
a. The regular panel has DC and AC components. I want to control the
AC elsewhere so I could order three slave units. The Midnite unit mounts
right under the inverter but I would prefer to have the OCP closer to the
batteries.
3. Outback:
a. We could purchase an Outback FX1000 and install three breakers in
it.
4. Breaker Size:
a. I have started to read the manual but I have yet to find out what
size breaker fuse is recommended. Have I just not found it yet?
b. Also, I have not found a specification for battery cable size. Am I
blind?
Thanks in advance. I really appreciate the help I receive here. I try to
give as well as receive.

I'm working on something similar. I think the Flex 1000 is the only
reasonable choice that can handle more than 2 of the large format DC
breakers. Midnite has the more expensive MNBCB -1000 Battery Combiner
box, but there just isn't enough documentation to figure out what it
can and can't do.

Hi William,
You might try reaching out to Roy Dyngen of SMA - he is a good contact for
these types of general questions. Email me off list if you would like his
contact info.
Is the SMA BATFUSE available in the US? Anyway, SMA has always recommended
connecting the negative of the batteries to ground when I called their tech
support line. As always, you would not fuse a grounded conductor so the
negatives wouldn't be fused. We've been using fuse blocks and fuses to fuse
our DC lines per one of my recent posts. It is certainly not the cleanest
way to provide over current protection but gets the job done and I think is
perfectly adequate. I typically fuse each string of batteries with a 175 A
fuse and use 2/0 wire. I think 3/0 is the largest that the terminal blocks
in the Sunny Island can handle -buried in the manual section 6.2.2 you'll
find that. A 175 A fuse allows for 6720 Watts of power (175 A x 48 v /
1.25) on the DC side or 8400 Watts before the fuse will blow and it
protects the 2/0. You will want to fuse each string of batteries before
combining them and running to the Sunny Islands.
I'll check out the products you've listed below and consider using them for
our next project as well.
Best,
August

William,
Are those the older Sunny Island 4.2 or 5kW units, or the newer 4.5 or 6kW
units?
Is this single-phase or three phase?
The SMA BATFUSE would work, but it is not available in the US. It's not Code
compliant nor UL Listed.
You could use the OutBack FW1000-DC, but you are going to have a little fun
doing the DC cabling and conduit. The older Islands had dual 1/0 battery
terminals. The newer ones have a single 3/0 terminal. Unfortunately, those
sizes are hard to find in proper flexible battery/inverter cable, mostly
because it doesn't sell in enough volume for distributors to carry. It also
doesn't properly match available DC breaker sizes, like 4/0 and 2/0 cable
does.
SMA worked directly with MidNite Solar to develop the MidNite E-Panel system
for the Sunny Islands. It's what I would recommend using. For one thing,
they have dealt with the DC cable and fusing size issues (and, no, you are
not blind). You can run 2/0 (4.2 or 4.5kW units), or 4/0 (5 and 6kW units)
to the E-Panels
However, I don't know offhand if they work with the older Islands. If you
are dealing with the older units, you should contact them to confirm that
they will fit.
If it's three-phase at 208 VAC, I also recommend that you use one of the
MidNite three-phase Master units (MNE250SMA-3PH-Master) and two slaves. It
has a three-phase bypass switch and color-coded bus bars for a full
three-phase system. There isn't a whole lot in there that you won't likely
use. The AC output on the bypass will just act as an AC main breaker. You
can then run that to an external load center.
Now, the distance from the battery bank issue is new. These systems have
been installed for a couple of decades now with up to 12 feet between the
battery and the first disconnect, breaker, or fuse. Of course, that doesn't
make it right, or compliant with the 2014 Code. The industry really needs to
come up with a good solution here. The Wrenches thread over the last few
days about placing fuses on or near batteries shows that an easy solution is
not available (or not known), at least not for flooded batteries.

Ray,
Way back in 2002, you mentioned using Boltswitch products for battery string
fusing
immediately outside the battery box. Might one of these be a partial
solution
for William?

box, but there just isn't enough documentation to figure out what it
can and can't do.

Hello,
I recently posed the question to Solaredge tech support, wondering if their
inverter, in this case a 20kw 480 3-phase, would have any issues if it were
connected to an AC panel backed up by a generator. They told me no problem,
for the inverter's anti-islanding will work if it sees the "generator
frequency" and therefore will not try to push PV power to the panel. But
isn't 60 hz, 60hz regardless of origin? There's got to be more to it than
that. I question this because I asked the same to SMA several years ago and
they were hard-set against connecting Sunnyboys to a panel with generator
backup, so I always would establish the point of interconnection upstream of
the generator feed. Comments? Thanks.
