handful are still active.
So if anyone knows of an internet-based service that can monitor DC (my
5.5kW Outback system) *and* AC (my 6.0kW Fronius IG Plus system), I'd
appreciate hearing about it.

27;s no time. I'm sorry to see it go, I found water
pumping projects challenging and interesting, but the tech cloning project
has hit some snags.

tes it takes the backup system
to roll up to speed, and if the big screen goes blank for a couple

backup fuel, it gets delivered and it doesn't spoil or evaporate with age.
But for something this big you'll pr

I eventually won this battle. We're happy to offer a wide range of Rennsteig
crimping, stripping, and cutting tools for MC4, MC3, and Tyco connectors,
plus a selection of dies so one crimper can handle all the different
connectors.

The BFS caps have a little fill indicator window. If it's white, the cell is
full, if it's black, the cell is low. A quick visual inspection will show if
you've got any non-fillers. (Floats stuck in the closed position, and yes,
they do occasionally stick, both open or

end-of-year rush in Europe was the rumor we heard. Allow a month or two for

with little track record

Just for the record, I'm enthusiastic about the other new SatCon inverters.
They're efficient, and logically laid out for easy connection in the field.

rs. Lately,
with all PV prices tumbling, they've been even less attractive. I think the
immediate future for Chinese modules will be developing country projects,
and very large projects where price points matter more than a dependable
track record or possible warranty service in a decade or two
Whoops! Careful with Solectria Kirk. Their LARGE inverters, 13kW and up,
are made in Mass. Their smaller residential inverters, 5kW thru 3kW are
made in Taiwan, and the 2.5 and 1.8KW units are made in eastern Europe.

Jay, there was a bulletin from Evergreen earlier this year about their
modules being used in positive ground systems. I don't remember the exact
details (and I'm not at work now), but the gist was avoid positive ground
till we make some modifications. Please check w/Evergreen on Mond
