Just about any inverter that starts with the word micro.

I should have mentioned it is the ES-195-RL. I was under the impression
that this module was not microinverter compatible due to it's lower
operating voltage. Aren't Enphase micros limited to 60 or 72 cell modules
(or multiples of 60 like the 120 cell Evergreen -FC3)?
The ES-195-RL specs:

If you have any concerns or comments about this, please respond to me OFF LIST.
Just some reminders, folks. I've been wanting to send some of these for awhile.
Now seemed a good time because there have been no messages for several days.

thank you for allowing this. it is very useful for trying to find old, matching
modules.

c2. From time to time people post items that they need but are having problems
locating (like an older model PV module to replace a broken one), but these
requests should be responded to
Jason:
I will let you run the calcs or call the manufacturers to verify the
concept works with these modules, but consider putting two in series into
one inverter. I rescued a Vanner install with SR100s by removing the
Vanner and doubling up the SR100s.

Evergreen ES modules are fine with 60 cell compatible Enphase microinverters.
ES-A are not.

Wrenches:
A local utility person has suggested that both the positive and negative
conductors from a solar array should be disconnected.
Disconnect both or not? 2008 NEC supporting citation please.
Thanks for your response.

See 690.13. There must be a means to
disconnect all conductors of a PV system. If it is a normally
grounded array you are not allowed to put a switch in the grounded
conductor, except for circumstances added in the 2011 code.

Kent:
In a normally grounded array, the grounded conductor is the negative
conductor, right? So, no disconnecting the negative conductor. It should
go straight through the DC disconnect and on to the inverter. Correct?

Okanogan,
Most often it is the negative wire that
is grounded, but not all of the time. Whichever is grounded should
have white or light gray insulation and it should have a
mechanical connector or bus bar connection in the disconnect
switch so that the grounded conductor
