Wrenches, William
Agree the push in connectors leave alot to be desired, however l have had
no issue testing voltage at the connector in SMA. The industry is making
installation of solar and for that matter most construction to easy and
screw in lugs require more time and skill.

I am with you William ! I also know that alot of rookies apply torque
quickly. Torque needs to be slowly applied up to the rating. This allows
the wire to take shape and not loosen up the connection later. Probably one
of the biggest sources of connection failures is a loose connection that
was
Friends:
Call me old fashioned, but I cannot get any confidence on the Wago
connector. It seems somewhat akin to the back-wire mechanism on a 15A
receptacle. This connection relies on a spring that is subject to
reduction in force when it gets hot. We have seen many of the back-wire
Thanks! I thought this was for Offgrid and that was my mistake.

it run a 15A table saw without losing power, or was that just too much
expertise? I will wait 3 years on anything that is suppose to replace what
I already use. I have a low opinion of the all in one for Offgrid anyways.
Dave A. - Sol-Arks'"GEN" breaker can be used for 1 of 3 operations only
- Generator, AC Coupling OR Smart Load (Load Shedding) So when you are
grid-interactive (which takes up your GRID breaker) and you have PV and
a Generator - the way to go is to have no AC Coupling - put the Grid and
Gen
Jason; From the Wago 221 data sheet, it's listed to UL 486C, 600V, 30A, Use
Group C (industrial) . I have a copy of UL486C, and voltage is just
specified for dielectric testing. That standard specifies tests with AC,
because it is easier (and cheaper) to generate and ramp up compared to DC,
and DC
I do not know much about Sol-Arc, but one can AC couple and DC couple
with a Radian or XW. The genset is on the genset input where it belongs.
For Offgrid AC coupling is just another way to damage a battery or genset
that does not need to be there. I suppose in a really large microgrid with
In another thread these connectors were discussed recently. There was a
question regarding the suitability for DC circuits. I don't think we came
up with any answers or consensus on that. I see the connectors are UL
listed to the 486C standard. I can't determine whether that is applicable
to AC
I like the idea of some small amount of AC Coupled PV for off-grid systems
when there is a known consistent daytime load. Around here the worst case
scenario involves afternoon air conditioning in summer, so some WSW-facing
AC coupled PV is an efficient way to cover that load and go into darkness
I would certainly agree with you all that AC coupled for off-grid is not
the best design choice. But just for clarification, this is a grid-tied
system where there is already an Enphase M215 system and a whole house
generator set up.
Cheers,

I have to agree with Dave on this, complex and off grid generally are not
good together, l sugest backing up and you might consider a redesign, dump
enphase, go directly in to the inverter DC side, now a gen set back up will
work. Your spending more time and effort going in a bad direction. AC
Dear Wrench Colleagues,
Also as a user of this list for over 20 years now - it has been
invaluable - not only for technical knowledge - but for the historical
legacy of decades of off-grid experience and community not supported in
any other forum.
I also contributed and may contribute more
