Solar MC4 connectors - needed? Why?

Now that you've had the system in operation for a couple of months, and have at least one field trial under your belt, do you have any additional thoughts?

Do you still like that MPPT controller, and would you change anything?

At this point I am very happy with the system.

We spent the last week of Sept in the Sierra, no generator at all, but the temps were mild and we ran the heater little. Not much of a test.

I just got back from 12 days in the Sierra, and nights were in the teens to low 20s at night. After a scary morning with ice in the toilet and slush in the faucets, I ran the heater 24/7 to keep things thawed. The solar easily kept the batteries recharged by midday, and the SoC did not taper down over the trip.

This would not have been fun using a gen. It would have meant running for hours every day, and my butt anchored in camp. Or more likely going home. The convenience of solar is worth the cost.

These batteries are 10 years old, and for most of that were undercharged by a WFCO junk converter. They are doing the job but don't have their rated capacity.

The Epever CC seems fine. No complaints and having the remote monitor inside the cabin is nice.

Would I do anything different? I probably would not use the Renogy panel mounts, and just make something myself. I chose a path that left options open. I could easily double the panel count, and the CC would handle it. Or I could double my battery bank, and it would handle it, including the wire sizing. I don't see any changes or additions any time soon.

To add, the pic directly above is close to the max charge amps I have observed, about 18a @ 14.6v, or 250w out of the 400w rating panel sum. I am not sure if that is good or bad. It seems reasonable to me, considering they are flat mounted, and in the autumn season, and a high pv to battery amphr ratio.
