If you have some small stuff yes but you can't fully have real power
just off the car's battery unless it's running. It boils down to the
capacity of the battery *ECR2* are small. 256W I believe. And the
ability to recharge it.
The cheaper the battery, the smaller the capacity. The cheaper the
solar panel is, the less solar energy it can pull.
I think the essential issue might be 'how much can be run at once with
a Go Power setup for 600$'. Can you run a cube mini-fridge and how
many hours off the input of just the solar panels under *average
condition* (**NOT IDEAL CONDITIONS**). Watch for that specifically as
normally you get only _ideal conditions_.
Case in point why 'ideal' is critical. My local NextDoor site is alive
with screaming people about the elecric bill in January. What was
backing it? Coldest January month on record ever. We all know that
climate varies from year to year, well, this one was colder and only
once before did we get more snow. That was in 1910 I think, and it was
13inches. This time it was 12.5. We had 10 days of heavy clouds with
most days getting freezing rain, then we got 12.5 inches snow. It took
5 days to hit enough meltoff to see roofs.
Chuckle, some not very well lit bulbs out there thought you could cover
solar panels with a foot of snow and they'd still be working. They
also didn't add up heavy clouds act like a blanket between the sun and
the panels. So, yes I and others got a bill. It was reduced by the
days we got enough light to cover some of it. Jan 2023/Jan 2024 pulled
600 kWh/597 kWh respectively. Jan 2025 was 463 kWh. 15 days of the
month (not normal) got little to no solar energy.
I didn't get my panties in a knot over it. Paid my bill of 150$
(highest before then was 51$) and moved on. What I'm saying expect
some days to not get any useful solar input. Have a plan.
Ted, you show good sense. Have backups for the crititcal things in
case the main system goes out or otherwise can't provide.
