William,
As long as it's a "standard" 60-cell module, and it likely is (it doesn't show
up on a Google search though), it will work fine with the M190. Just make sure
that the Vmp is in the 30-35VDC range, and the temp-corrected Voc is not over
54VDC.

Oh my gorsh !! That's a $4000 coffee machine !!
Sounds like it needs a low pass filter coffee filter though.

William,
Unless you're into various forms of self-abuse, I don't understand
why you'd spend time on a system from a customer who "bought some
modules and M190 inverters from an E-bay vendor". The customer
won't appreciate what you offer.

Colleagues:
I had occasion today to use the Enphase on-line compatibility
calculator. My client bought some modules and M190 inverters from an E-bay
vendor. The exact module model number was not listed on the compatibility
list so I was recommended by Enphase to use the calculator.

First, a water main is no longer allowed to be used as the primary
grounding electrode by itself, it needs an additional electrode added to
it 25053(D)2. You still are required to bond to it 250.104(A)1, but it
doesn't count as the electrode. Also, 250.166 (C) specifically lists
pipe as one o
Hi Ray and All,
250.166 says the GEC must be sized as specified in (A) Not smaller than the
neutral conductor, or (B) Not smaller than the largest conductor supplied by
the system, except as permitted by (C) through (E).
A water main [as in 250.52(A)(1)] is not listed as an exception in (C)

I believe these problems are mainly due to the high frequency switching
content of the typical sinewave inverter

Hi Ray,
Thanks for that information. I'm glad they covered that. I never
install more than a #4.
The question I'm still not sure of is weather or not we need to
ground the DC. I always have run a GEC to the DC. It would be great
if we didn't need to do so on the Sunny Islands especially,
Ray,
Thanks for the note and I see your point about "operating at greater than
50 v". Does anyone else have an opinion on the operating voltage for
batteries? I know that NEC 480.2 defines the nominal battery voltage as 2
volts per cell for lead-acid and I believe I have a code interpretation

I'm having a similar issue with a GRID-TIE inverter just now. SMA 5000US which,
when it wakes up every morning, removes the date and time from the programming
in the customers' Monitor brand kerosene heater. They have to re-enter it
daily, which is annoying enough, but when they go out of town,

Unfortunately, probably a different coffee maker.
I've gone through this with several different appliances over the years on
sine wave inverter output. Washing machines, refrigerators, dishwashers it
could be anything with electronics. Specific manufacturers typic
Hi Drake;
Read down a bit more and 250.166(C) and (D) limit the size of the GEC to
#4 or #6 max., depending on what electrode is used.
This used to not be the case, and systems in the 90s had 4/0 cable to a
5/8" electrode: which just like your 1/2" pipe example was absolutely
ridiculous.

This is a fairly complicated issue. I agree that an ungrounded
battery system is safer than a grounded one, since the hot wire will
not arc to the casing of the enclosure.
If a system has a charge control and an array, the negative wire of
the array usually needs to be grounded (or have a fus
