When net metering became available in Va. in 2006, we wanted to upgrade and
enlarge a Y2K battery backup system using the Trace Power Panel
and Kohler 8.5 RMY generator. So we became one of the first on the East Coast,
judging from serial number, to use the XW6048.
A couple of the early units
Check to see if their meter goes backwards. Some utility meters actually
charge for power when you are selling.
Or maybe they have no wind and a new big flat screen tv that they leave on all
the time.

David may be on the right track.
Check for a newer digital watt-hour meter at your customer's location.
Newer watt-hour meters have two channels of metering in an attempt
to thwart people who used to flip their mechanical meters over (usually
at night) and run them backwards to un-use power, and
The system only uses grid power to charge batteries, they have two FX3048T in
parallel so I don't think the meter is the issue.
They did send me a picture of the two wind towers, one is 20 feet off the
ground and one is 60 feet off the ground... No wind would be an understatement.

Jesse,
Are you sure that you even want to take this on?
20' wind tower, 500 watt (rated) machines, four battery strings in
parallel - the design itself has enough weakness, based only on
the scant information that you have provided, that it might not be
It would be good to know how much energy the wind turbines have been producing,
if any, if that information is even available. Eight batteries per inverter? Two
separate banks? They installed the system? DIY? In any event, it sounds like a
situation you want to approach with caution. The crux of
Wrenches,
I would like to here some thoughts on monitoring the production a XW in grid
tie with battery backup mode. I normally use the Sunny Island for my grid tie
with battery backup systems and am considering going with the XW on my next
one. Just wondering where in the system one would
Two 1-kW wind generators doesn't sound like enough to provide energy for
a household except possibly in the best circumstances. If there isn't
much wind, the system is getting most of it's energy from the grid. The
utility bill would go up even if they were using the same amount of
energy in
I do not want to take this on! The wind, from what I have gathered is an
absolute bust. Just doing a little online research it seems like they are
getting next to nothing from the wind generators.
From my little understanding of the system and reading replies, I would say
they are buying
i am not understanding the 'wisdom' of using non-grid tie inverters in this
application. it is pretty easy to modify the inverters (board change out) to
grid tie models, which would allow the inverter's to transfer the loads to the
grid (internal transfer switch) and 'sleep' until there is an
Im with you on the wisdom of it.
The problem with my area is that people maybe good a grid tie, but there
are very few people that understand the off-grid applications (DT is the
only person I think is worth listening to.) The contractor they chose was
the only contractor the home owners spoke
Hello,
I've been having a long conversation with a local guy
about disconnects that are usable in DC PV circuits. From what I have
seen, GE, Eaton... they are usable up to the 250VDC it has listed on the
labels, or more if poles are wired in series. The squared D 600Vac/dc is
self tested to
Anyone knows who still might have a stash of Schott 240s available for sale?
Thanks,

Jesse,
Sometimes the best thing you can do for a customer is document, in
writing, what's wrong. And walk away if they aren't willing to fix it.
