Solar question-help needed

[Jafo]

You will want to make sure your controller can handle 800 watts or consider configuring your array for 24 or 48 volts by wiring them in series.

Jafo, right now it's just a cheap off brand 100 watt panel, a cheap controller and a couple 12 volt deep cycle batteries.

When I do the "real" system next summer . I will probably buy a package deal so it will all match up.

I second the idea of using DC->DC converters instead of 120V if you really don't need it. They make them for various laptops, along with the stuff already show here.

However, it's also worth just running it all the time and seeing if it keeps up. It might seem wasteful, but the solar power is free at this point. Naturally it will vary by time of year. If it keeps up in the darkest average times, you can avoid all the extra complexity.

Also, adding a second cheap panel that's mostly compatible is probably easier and cheaper than all the timers, etc. Or trading the one you have and a little cash for two that are compatible and can be wired in parallel.

Just playing with the components right now. In the spring i will get a full system in and then just powering the cell system and camera won't be an issue.

Snow has started to fly up at the yurt so the best I can do is maybe trying the 12 volt timer to limit the time the inverter and booster run. However, it's been over 7 days now and I'm still up and running so maybe the one panel is enough or its just adding extra time until the 2 batteries drop in voltage.

We shall see, I don't think I will be able to get up there for a couple weeks.

I sold the snowmobiles and bought tracks for the side by side at the wife's direction . She didn't like the snowmobiles.

If you don't mind, please update us on how well that works in deep snow. I have been contemplating buying one, but only if I can ride it in like 3-4 feet of snow.

We will see. We had 7' last winter.

Sold my snowmobiles so it better get us there.

I let you know.

Just thought I would post an update..

System dropping the voltage to to 5 volt is working fantastic.

The 100 watt panel is keeping the battery charged and Im actually powering the booster 24/7.

Jafo no update on the side by side with tracks yet. Just a skiff of snow so far. Drove up yesterday in the truck.

What stepdown are you using for the 5v? Do you have a photo of it? I am considering doing the same thing.

This is the one I used
