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

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

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
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.

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 throug
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 h
David and Wrenches,
With several recent mentions on the Wrench board pertaining to PV fire ratings,
and AHJ interpretations of the 2014 NEC we're hearing on this issue, I'm
concerned this is a volcano on the verge of eruption.
I recently attended a large meeting of Texas AHJ/CBO officials where
I started using automotive SAE rated resettable circuit breakers like these:
http://www.delcity.net/store/Hi!Amp-Surface-Mount-!-%3Cbr%3EManual-Reset-%28Switchable%29/p_193073
I'm only using these on smaller stand alone (non NEC) off grid systems,
but they are sealed, and allow protection right a
Mark,
You should know better than anyone else that you can't corner the sun
market. If you read the reports you will find that your deepest fears are
unfounded.

I have them on my system at home and on a system at a local community college.
I like the data available from the system. My system had shade issues so I like
the idea of them with issues suck as mine.
I mounted the gateway device in the attic bellow the array instead of outside
at the array.
So does this help understand why Sunrun bought REC and Snap n Rack?
Going forward the only installable equipment will be provided by large
groups that can afford to test and rate their own panel with specific
racking systems that they also own?

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

I look at batteries the same way as modules each string gets it own
protection, its good for trouble shootings and for safety. we use the
magnum Energy Class T fuse and holder, its cheap and works very well. If
you have ever seen a short of a battery bank you would always install fuses
right there
Are these listed in the 2014 code (diameter, ampacities, etc)? I don't see
them in the usual Ch. 9 or 310.15 tables. Am I missing it?

Hi David,
Can you elaborate on the mounting system(s?) that would minimize fire
propagation?

We did one recently. Interesting concept. If you have 5000+ watts on a
5000W inverter with a 1500W SPS, you should have a pretty good window each
day where a good portion of the 1500W is available. I wouldn't rely on it
for more critical loads like ref
