Wrenches:
Thanks for all of your good feedback. I will be discussing the situation
with our customer. I will let you know what the resolution is.

Hi Bob-O,
Thanks for the PR update, in which one thrust appears to be an all encompasing
/embracing appeal by listing the affiliations of the Board members. Any reason
the website doesn't list the actual Board members _with_ their formal
affiliation titles (i.e.. member, president)?
I

Hello, all~
Since the original spec called for Cadweld joining of the various ground
electrodes, all of those will be at identical ground potential. Cadwelding
unifies them so thoroughly that they behave like a single electrode...but
with bigger surface area.
I suggest that lightning loops are
It all depends on how its done. If each electrode is attached to the next
electrode by the #2 and Cadweld directly, and also connected through the
required EGC, then there is a loop. Once you have the loop, the low resistance

I like the SW4024, but I never liked the SW5548. It actually had less surge
capability than its little brother.
Either way, I would never recommend the Trace SW series for grid tie. They are
very inefficient in that mode.

My biz partner has an Enphase system with BP Solar mods.
He believes that the web-based monitoring system may be reporting on the
high side as far as kWH performance over time.
That is, he suspects that what he's seeing may not be accurate.
Anyone out there have a similar experience?
Hey all,
I am trying to size a PV/generator system for a 10,000 ft2 off-grid
hunting/snowmobile lodge with outbuildings. The goal is to significantly
reduce current generator run time. I was wondering if any of you have
experience or suggestions for calculating time of use of lights, etc in a
Hi Marco,
We definitely experienced an overstatment.
We have a client who installed 5kW on a string inverter and 5kW on enphase
and it is that side-by-side comparison that enabled us to positively
identify a problem. There was a significant overstatement of output. We
finally got a Enphase

We attempted this about 2-3 years ago for a project on one of Ted

Provens and a 3-phase Sunny Boy/Sunny Island system. Due to the lack of
