Jason, If the pictures of the E18 & 19 are accurate, and from my
conversations with the different suppliers that include SolarBridge
inverters, several of these use the original Pantheon I instead of the
updated Pantheon II model. Apparently there are differences in the locking
clip in the module c

The Power-One 250 and 300 watt micros, when they start shipping them, will
do the trick with the SPR 200 series mods.

I do have a contact who is beta-testing the units and will see if he has any
more information or wants to comment.
I believe that current flow through two parallel conductors
is inherently balanced by ohms law. I think the reason the NEC
prohibits parallel cables below 1/0 is to stop contractors taking
shortcuts, using two conductors just because it was what they had.
electrically it works fine. At some point y
I have a bunch of them but have never had enough solar to even think about
hooking them up. Efficiency is a problem as is the unusual voltage they run
at, It just seems strange running an odd number of cells.
The Classic will handle it well but I am getting to the point where I want
things to go
The code provisions regarding conductors in parallel [2011, 310(H)(I)] are very
specific and make complete sense. When installed correctly, in larger sizes, 1/0
or greater, as permitted, there is very little likelihood of significant
difference in resistance or any other problem. This is done safel
Mac,
I have had good experience with the Fluke 1587 (Hybrid Insulation Tester and
Multimeter). Usually retails for under $750.

I have 5,000 pounds of original Edison
NiFe batteries, made between 1928 and 1939.
Almost all of them are working at close to 90% of their original

I would be willing to bet that Edison was really close with his

Good points. I would think a more dangerous situation would be the case
that you often have with large parallel feeders landing on a single OCPD.
If one wire has a little less resistance, it will always run hotter than
the other, and you could easily overheat a wire that is protected by that

Wrenches,
I am looking for a good reliable insulation tester at a good price. Does
anyone have a model they like? Is there any reason to get one that can do
above 1 kV for residential and small commercial PV systems?
Thanks in advance

Code issues aside, even two seemingly identical runs each with breakers would
have at least slightly different resistances, causing the lower resistance run
to take more than half the total current, tripping the breaker in that run,
then causing a tripping of the breaker in the other run.

Forever? Well, at least Edison thought they should last 100 years. As mentioned
by others, inefficiency is an impairing factor in an RE system. However, due to
the all time low cost for PV solar modules, these batteries can actually be a
viable option. If you have the space for 40% more PV power
