Kelly,
I have installed several of the Metrima BTU/KWH meters for SHW. The kit
comes with a flowmeter, temperature sensors and wells (hot and cold), and a
calculator, nicely integrated. These are utility grade meters and more
economical than the hardware you mentioned(dealer price $425). Check
It would seem to me that a properly designed off-grid system with a properly
engineered battery (or other) back-up subsystem would provide a continuous
source of power. One may need to do a load calc to show that the PV system
(under a suitable worst case scenario) can indeed provide the 24 hour lo

Jeff, this sounds like a job for Donuts! It sounds like their position is
possibly based on a local requirement or perceived requirement, independent
of the NEC.
Jeff:
There is a passage in 690 that declares that a power panel does not have to
be fed with the amount of power it is rated for. This means to me that no
permanent power feed of any particular amperage is required. Good luck.

Kelly,
IMC Instruments makes a few differential controllers that have the ability
to provide data output for logging & analysis.
I have installed one, but have not yet done any data logging; it looks
promising.

Jeff,
I had a couple off-grid installations (newly constructed homes) where
the owners could not get their certificate of occupancy until the
off-grid system was installed and inspected. Once it passed they
officially could move in.

Thank goodness this was not my project, but I just received a call from a couple that had purchased an old farm house in a rural part of the state that was almost a mile from utility lines and never had power. They are renovating the old farmhouse and applied for all permits from county and have n
Hey, old friend and neighbor,
Given that you live with the abandoned Aermotor windmill on Old Windmill
Trail at the bottom of your driveway ("yard art"?), I suspect that you'll
come out just fine in the water department. My toes are crossed for you for
the "sweet" part.

My building inspector does not allow grade level tanks as the
warm temp adds to bacteria growth.
I agree with Darryl about putting the tanks underground, otherwise they
become veritable cornucopia of bugs a

There are a number of temperature modulated units out there, the Rinnai and

Todd,
Having already mentioned my using the Bosch Aquastar (I'm completely
happy with it), your original question was concerning a good 24 volt
pressre pump, I believe. The best one I know of is one that we sell, so
I think it would be best to contact me off-list - or on the m
Ian,
I have a Bosch Aquastar hydro-ignition unit, but no solar feed. I
originally had a Myson tankless heater (you probably remember them) that
I bought with the misunderstanding that it would modulate according to
input temp, but the standing pilot was kind of a drag, even if the unit

Hi Todd and all,
Since this is a renewable energy list, I think it's worth mentioning
that installing a modulating demand heater will make the installation
"solar ready".
I'm only aware of one tankless heater that accepts pre-heated water
and has no electrical usage, and that's the Bosch 16
My understanding of the Bosch Hydro units is that there is just a hydro
generator in the water line, no other gear, water runs, it sparks and
lights.
the service manuals I have do not have that model in them. I plumbed one
last summer and don't remember any controls, they are as simple as can be.
Evergreen 195's probably... service is 3p 208.

Eric,
What are you using for modules? I'm a big fan of the SMA inverters--very
reliable, easy install, excellent support.
There's a good article in the new journal Solar Pro deals with this
issue of multiple small inverters vs. one large

Hi Todd,
Congrats on the off-grid solar application to improve quality of life.
I will defer to my more learned colleagues re the optimum water pressure pump.
If you don't want to use any electricity to create the hot water, then you want
to use a natural draft tankless. (Like a conve
