Matt,
The Enphase and revenue grade meter are in disagreement by less than
1.1% in the system you are describing - that's good agreement! According
to the Enphase white paper, the wiring loss in the Enphase cabling
between the first and 9th inverter is 0.6%. That only applies to the
last inve
Kent,
Can you help me understand the 1.1%? I had figured over 4% and allowed
that 1-2% may be voltage drop (though it is quite literally 12' of 10 awg
between the last enphase and the meter).
In a state with a semi-active SREC market all our systems are installed
with a revenue grade meter. I s
Kris, I worked traffic signal systems for years, we spliced conductors in pull
boxes that fill with water on a regular regular basis. There are products
available that are rated for waterproofing connections and the THWN-2 is rated
for wet locations, but I don't know about submersed locations.
Thanks for the input, all! I can't wade to dive into this project, now.

Why not use submersible pump cable? It's readily available in different wire
gauges, usually from a Well Driller or Pump installer. Some bigger
electrical supply houses carry it too, and have even seen variations in Home
Depot.

Wrenches braintrust,
I'm working up a bid for a battery/inverter powered series of "T8" style LED
4 foot lamp tubes. They use no starter or ballast but the effect from the
inverter waveform is what I'm in the dark about. I have a feeling that any
modified square wave might wreak havoc on the LED ci
Hello Wrenches,
My employer has the inside track on a 1MW install on .5/12 standing seam
metal roofs (two separate roofs). This is by far larger than anything we've
designed so I am looking for a ballpark cost/watt. I'm at around $4/watt. I
realize there are lots of variables and I am looking for
Yes, you're in the ballpark.

Hi Wrenches -
Most of you already know this, but California solar data, including
installed costs, is public information found here:

Searching for data on other ~ 1MW systems will help you hone in on at least
a ballpark figure bu
Friends:
I don't know if any of you share my feelings, but I am not real comfortable
corresponding about bidding on this list, for these reasons:
1. I thought this list was for mechanical / electrical / technical issues.
2. Anyone would be a fool to let someone else ascertain a bid for
them.
William is right, there is another list that is suited for these questions.
Ask Michael about it.

I agree and I knew it and I apologize. I fervently resisted doing it but my
boss insisted and so I kind of didn't have a choice.

Matt,
You're right, it is 4.5% different. I'm not sure which buttons on the
calculator I used to get 1.1%.
