Update: SWWP also kept the Whisper 100. The 200 and 500 were sold off to
Luminous India http://www.luminousrenewable.com/. I am told there are some
problems with quality coming from them.

Hi Wrenches,
I imagine that all of us working in rooftop PV have put some good hard
thought on the best way to get the modules up to the roof. There are
various lifts on the market, you can hoist them with ropes manually, or
walk them up a ladder (sling them over your back). I find that the
While I haven't completely convinced the latest inspector about PV not
being mechanical equipment, I'm running into another issue.
I decided to try out the new Midnite MNPV6-AC combiner for Enphase
circuits. Because there are overcurrent devices inside, the inspector now
insists that NEC
It is not possible to maintain three points of contact at all times while
carrying a module up a ladder. It is my understanding that if three-point
contact is not possible at all times, then a personal fall arrest system is
required. This is not called out specifically in Subpart X
I agree that its impossible to maintain 3 points of contact on a ladder
while sliding a module up above you. I've done it many times but I agree
that its probably not kosher according to OSHA.
This reminds me of a product idea I had with a friend who does canvas
sewing for boat covers and such.
Hi gang. Home Power featured a simple, DIY module lift in Issue #143.
Contact me off list if you do not have access to the article and are
interested.

I see in your signal capture that the
firing angle is earlier than mine so that it doesn't (always) go
across the zero crossing. From what the utility system operator
here has told me about their TWACS, the firing angle is adjustable
from about 5 to 30 degrees
Enphase engineers have contacted my client and will do a preliminary test
of the Enphase fix sometime next week to see if it is effective. They will
be using a Hioki PQA during the testing. I applaud Enphase for staying on
this and even if this first fix needs some tweaking, I am confident they
I'm with your inspector on this.
I don't install fuses or breakers on roofs

Jay,
I assume you mean pitched roofs, or not readily accessible flat roofs. This
particular project happens to be a flat commercial roof, but with no
permanent ladder or hatch. I really didn't have to use the MNPV6-AC's, but
it made sense in this case (excluding the access issue).
Looks like my
Might be a good application for the Midnite Disconnecting Combiners, with
the control unit on the ground.

On Thu,
Eric and Garrison -
Yea, I see your point. I was questioning the ladder method because walking
modules up the ladder seems to be the standard for roofs 2 stories or
higher. I thought maybe some folks had a different interpretation. I'm
particularly interested in seeing what Solar City is doing
Several types of lifts are available at rental yards. We've used a hand
crank type air conditioner lift to move 8 modules up at a time. For
anything over 10 modules, its really a good idea to use something
besides a man on a ladder, especially with today's larger modules.

Hi Jason,
Is it possible to install them on the side of a building?
And Dan's suggestion for the remote midnite might be perfect.
