Does anybody happen to have a temp sensor for a Xantrex XW inverter? This
is the type that bolts onto the negative battery terminal. I am not sure
but I think the Magnum temp sensor may work as well. We have been trying
for weeks to track one down for a customer from our distributors and

Hello Wrenches,
Mexico has recently allowed, at least theoretically, net metering. Does
anyone know if anybody is actually net metering in Mexico?
If so, what all is involved with foreigners installing systems? I know
that there is approximately a 30% additional equipment cost with duties

Drake,
My Uncle lives in Guadalajara and has recently installed (4 months ago) a
grid-tied UPS system. He did purchase an Itron net meter from CFE and has
been selling power to them at retail ($.25 per kWh). He sent me a DIY guide
and interconnection agreement to easy the process for some of our S
Wrenches,
I am designing a system with both wind and solar backfeed and I'm having
an issue with the utility. They say we need to have a single renewable
disconnect switch before the grid backfeed. The solar is designed to backfeed
3-phase through a meter, then a fused AC disconnect to
That 5 pole disco will be one extremely expensive piece of wall art! The quick
and easy (albeit not perfect) solution is to put it all into your AC combiner
panel as you suggested and place the wind production meter before the wind
input breaker. The solar production meter will now be net of bot
I think the NEC passages I am recalling (300.3 C 1, 690.4 B) refer to mixing DC
and AC in the same conduit, enclosure, etc. I cannot find anything that would
prevent me from disconnecting both wind and solar from the grid in one switch
enclosure using a multi-pole switch. They will be electri
My AHJ is making me ground the Enphase inverters AND use a separate
equipment ground for modules / mounting rails.
The panel frames are grounded to mounting rails via WEEBS, rails are
grounded together using WEEB lay-in lugs and copper wire, this ground wire
makes its way to AC panel gnd bar, wher
As an aside, why didn't you use approved WEEB's to bond the inverters to
the rails? This eliminates the ground wire to each inverter. Simpler
IMHO.
Anyway, what we are seeing in some jurisdictions is the requirement for
the additional grounding electrode (690.47(D)) even when there is a good

I hope i do not muddy the water here. if you have 3 phase delta, usually the
single phase transformer is larger, can you do the solar in split phase?
Also staying with the 3 phase, why not use a three pole service rated switch to
Line side tap, and use two poles for the single phase and the

The solar backfeed is about 85A, the existing 3-phase panel is about 300A
and
drives 4 AC units and parking lights and the existing split-phase panel is
about
200A and drives office equipment. I think I'd rather drive the 20kW directly
to
the three phase to alleviate the AC loads
Chad,
Great that it is really happening. I would appreciate getting a copy of
the DIY guide and agreement. Do you need my address, or is the
information electronic.
Thank you,
Drake
