Ceiling screws

Almost all the screws came out fine. Only had to drill out 4 of them

Sounds like you've got a handle on the electrics. So many people come in without that!

Bus is looking good. Looking forward to following your progress.

Thanks.
My background is electronics, my career was computer science and I have way too many hobbies and a nice shop to entertain them.

Having too much fun since I retired

Will need a genny, unless shore power's available a couple overnights per week.

Run it in the mornings when you know solar won't be enough to get the nank back to 100% Full.

Good SoC monitoring will help tune your intuition as to when that's needed.

Consider LFP too.

Solar limits

In the Seattle area, the summer is Ok (about 5 equivalent solar hours per day). I think this would be enough to charge the bank fully from depleted in one or two days (assuming minimal usage). I'm not sure yet what my overall power usage will be but initial simulations look like I'll use half to 70% of the 10kW battery capacity on a daily basis.

On good days, I think I'll be OK. ..

In the winter the average is only about 1.6 hours equivalent sunlight... This means I'll only generate about 3600WH of power... Not enough for the batteries to recover unless I use little hot water and little heat...

For a generator, What's the consensus? Is it better to go with a "built in" diesel (expensive) or go with a portable generator?

I've been looking at the Champion 3100W dual fuel inverter portable Generator as one option.... but then I'll need to either carry gas or propane.)

Also looking at some Diesel inverter generators (expensive... about $8K)... It would be the "ultimate" though.

Whatever you get make sure it's **quiet**. Start cheap see how you go, upgrade when the first one dies.

If you stick to lead, learn how to measure SoC and how to ensure the bank is truly 100% full, as per mfg endAmps spec, a quality set can last 7+ years.

Also keep in mind that the wattage ratings of solar panels require optional conditions and if you aren't orbiting the sun you won't get those maximums! My 400w set occasionally gets above 200w actual.

If that is true in the full summer sun at noon, something's wrong.

I agree in winter far from the equator it's normal.

design updates - Solar Panels

Some more design pix. Solar panel layout on the roof.



It's not quite right.. I haven't figured out how to get Inventor to bend the panels to fit the roof profiles...

This is if I install al the panels... I still have some solar water heaters and venting to include here somewhere...

I also haven't added in the tracking systems.

There are flexible panels but I have no idea how they compare to fixed.
