Colleagues:
We are in the middle of our first Enphase installation. I have been
working closely with the crew on this project and dedicated extra time
because we knew we needed to develop some new procedures to accommodate the
new technology.
My most surprising realization is that with the
Ryan,
If you haven't tried the Apollo Solar controller you might consider it.
We have many installed and they seem, after an intially rough start, to
be a superior product. I have yet to use the high voltage model but
plan to at the first opportunity. You can configure the panels to 200
VDC OC.
I see Friday the 13th has arrived all bright-eyed and bushy-tailed one more
time just like clockwork. But now it is wearing horns as well. That's some
conundrum you present about keeping your competitive edge in a dicey business
climate. What if you sold your wiring concept to Enphase on a
Hi fellow wrenches,
We just inherited a two year old off grid system consisting of a separate
home and a big shop/garage that has a mechanical room and battery room. The
OBFW500 power center feeds a main/meter panel. The two Kohler generators
(25kW LPG 60kW Diesel) feed a transfer switch that
Try 250.32. In this case, you consider that the panels at the home are not
actually new service enterance equipment. The service is up at the shed
and the home is part of two or more buildings supplied from a common
service.

Jim:
We have spent considerable dollars pursuing patents pending and hope they
provide future return. Our little wiring techniques are not unique enough
to patent and if Enphase really cared, they could figure out better
techniques to hold wires in place, but I do not belive that is their
William,
What do you think about the reliability of the Tyco AC connectors used in
the Enphase system?

If you can wait for the Morningstar MPPT 60 you should try to. It is
outstanding, and the controllers have been shipped out for distribution so it
is not vaporware.
We have 3 of them running here for almost a year and the controller has
slightly better output than the original MX60, so

Some feedback:
1. The DC and AC wiring is generally under the modules and therefore protected.
2. Upon the wiring segueing out from under the modules- AC, you would switch to
a JB and conduit. This can also be achieved prior to exiting below the modules.

Kent,
Thanks for helping sort out this issue. At a
minimum, the majority of the portable generators
being connected to wiring systems today are not
code compliant. Fortunately, the connections
haven't created incidents, since these systems
have become very common. Off grid installations
Mark:
I like the fact that they provide a perceivable detent when the connector
lock is completely tight. I am not qualified to judge whether they will
last the 25 years the modules are rated for. The beginning of the chain
sees low amperage while the end sees the total amperage. The pins
Drake,
NEC 250.142 discusses using the grounded conductor to ground
equipment. It doesn't apply to portable generators, except within the
generator itself.
