So these won't work? I thought 60v was max?
60V is max.

Voc of a solar panel increases as the temperature decreases.
25.18V is measured at +25C/+77F
There is also a tolerance +/- on that 25.18V

Should work to about -4F give or take. You'll need the manufacturer's numbers to calculate.

According to support they say to connect panels in parallel only. Would this be safer?

Yes, safer for these panels.
You'll need to buy the adapters shown on page 6.

No you don't need to buy any adapter.
The S2000 has shitty solar inputs but you don't need to wire the 2 panels in parallel(aka needing adapter).
Using the branch adapter to wire the 2 panels in parallel would be a waste because the S2000 only allow up to 12.5 amps.
Wiring in parallel would put the panels at ~18 amps.

You just need to buy a XT60 => MC4 cable. 12 awg cable is fine and should be cheaper.
Wire the 2 panels in series, then hook up the + and - and then XT60 to the S2000.
Wiring in series would put the panels VOC to around 50v(the S2000 allow 60v) and that leaves you plenty of room even if the panels jump in voltage.
In theory, the 2 panels should be running around 40v-42v at ~ 9 amps which should get you around 350w to 380w depending if you get the good panels or not. At the worst case scenario, you should still be getting 320w from the 2 panels.

Is it safe to presume these do not include anything but the panels?

Good deal on panels to match with the S2000.

It's a bummer Anker doesn't include at least the XT60i to MC4 cable. I guess they thought many people don't buy panels.

Yeah I need to find a cable for mine, I want like 50ft since I plan to run the cable from a window from the side of my house to the front for the panels during a lengthy outage.

For 50 feet, I'd buy 10 AWG MC4 extension cables. Lots on Amazon or eBay.

Then buy the XT60i --- MC4 from Anker.

I keep getting "For security reasons your request can't currently be processed" when I try to type in the DEALUS10 code for the 2 pack.

Edit: I just refreshed the page and it worked. Thanks op.

Hey I can post pictures now.
These are my Eco W 195 panels. 16 of them.
I get on average over 10 kwh per day and a full sunny day will get me 14kwh
I don't move them around so I don't actually get full sun on these array until 11am.
I'll post pictures of the Aeternasol when I get them up. I have 8 of them now.
Did you buy those racks, or did you build them yourself?

What's the difference between n-type and p-type solar panels

Can anyone confirm that these do not have bypass diodes? I read on a forum these do not, so if wiring in series and a leaf covers it basically the voltage goes to 0
