Jay,
This has been my go to relay for the last 21 years, no failures. In all
sorts of environmental conditions.
Unlike the generators they are supposed to start...but I digress...

I would use a sealed relay.
The SS one should work. Or a 12v cube relay like in cars.
Super cheap and reliable

Dan:
I think a solid state relay is indicated here. There are many out
there. Here is a link to one at Digikey:
https://www.digikey.com/en/products/detail/wago-corporation/859-739/15520805
The datasheet (attached) shows operating limits of -25 to 70 degree
C. There are other options at Digikey that work down to -40 degrees C.
Good luck,

*Subject:* [RE-wrenches] In search of better generator start relay
for Outback system
Esteemed Wrenches - Finally successfully troubleshot an intermittent
AGS problem that has been nagging one of my remote-grid clients for
1.5 winters now. Of course it's a 4-hour drive from my office.
During winter snowstorms (when they need the AGS the most of course)
the generator had only about 50:50 chance of starting. So I'd travel
to the site (sometimes just the client would do it and I'd guide him
by phone), pull up the Gen menu on the Mate 3S, hit ON and it
wouldn't start. No bueno. Walk up to the generator (propane with
Honda engine) and verify it's on Auto. Start it with the main switch
to ON, starts right up, so not a gen battery problem. Run it for an
hour or so, stop it with the switch on the gen, put it back to Auto,
and everything works perfectly from Mate 3S AGS for 1-2
days, including remote start from OpticsRE. Then the problem
(sometimes) comes up again when nobody is there.
I just happened to hit the site at exactly the right time last week
right as a big snowstorm was moving in, and was finally able to
figure it out with really good raingear and a multimeter: The Outback
Flexware remote gen start relay OBR-16-DIN was icing up internally, I
had added it in the gen compartment when we upgraded the client from
an old Trace SW to an Outback (SW had a big AGS relay, Outback sent
a 12VDC signal to trigger the external relay we added).
DIAG - new Outback OBR-16-DIN relay would get frosty internally when
high humidity snowstorms would move in, that's why it sometimes
didn't work from the Mate 3S or OpticsRE. Run the gen for an hour,
the internal gen compartment warms up, the frost melts off of the
relay, then all the AGS from Mate 3S and OpticsRE works fine.
Have any of all y'all run into this problem, and is there a more
reliable relay to use that won't ice up? not outside exposed to
weather, but inside the outside gen enclosure. I have zero space
available in the VFX MNDC enclosure in the house to put in the
Flexware AGS relay, it would need a separate enclosure.
The easiest solution I can see is just find a relay to fit into the
gen compartment that does the same as the Outback version, but
doesn't ice up.
Thanks in advance for any and all suggestions.
