That's true Dan. "Not all of the current" would be on the larger wire, but
most
would be, assuming that the old #10 and the connections are still good. And
hopefully, it isn't landed on the 12V terminals on the back of the
refrigerator.

I think you have to send it in. I have 2 so I do one at a
time.

Sorry for the long post. I don't know how else to communicate this issue.
We installed an Energy Recommerce data system on a project last year that
we have not been able get working properly. Everything works except the
monitoring of the series string amperage outputs from the solar array.
There ar
I see that one does not have to send in the calculator
anymore. This makes it even better.
Thx.

Hello Wrenches,
I'm looking for a panel which will provide
0.7A at 12-20V
with only a 60 lumen light source for the irradiance source

We built a display for a Science Center shining a 350 watt halogen bulb onto a
20 watt module. We could get .4 amps out of the 12 volt panel. No matter how
large the array it can't be done with 60 lumens because the light disperses at
the same rate that the array surface area increases.

If the source is a light bulb or similar, no it cannot be done at all. If
the source was something like a very heavily clouded sky, or twilight in the
Arctic, it could be.
A 23 watt CFL puts out around 1200 to 1600 Lumens. So to get the wattage
needed (.7 amps @ 15 volts), you would need a pan
Do you have any wiring close to the actual sensors or circuit board that
might be interfering with them?

Hi Wrenches -
We were called out today to check out an under performing system installed
by another contractor. This is an odd case.
The system has 24 Suntech 180s in three strings of 8 and a SMA Sunnyboy
4000us. Open circuit voltage for each string was about 330 Volts and we
verified that everyt
This is a pretty good example of how obscure the various "lighting"
variables are for even solar pros.
I won't go into the gory details (and they are details of some depth, trust
me). So let's take the following shortcut.
A decent CFL puts out 60 lumens per watt of power consumed. So, in theory,
Thanks Peter, I was trying to figure out how to translate from lumens, good job

Hi Vince,
I don't know anything about Energy Recommerce, but a search of their website did
not result in finding an installation manual for their combiner box, only a
datasheet. You stated countless hours were spent on the phone with their
technicians. If it was my job, at this point, I would want

I had a similar experience a couple years ago with a Fat Spaniel string
monitoring box w/ Hall Effect sensors, on MODBUS comm, etc. The folks at FS
couldn't help at all, and like you I spent countless hours on the phone with
the technicians to no avail. Then I found out that their boxes were
