My Solar Shed Construction Starts in a Week

Array on the left is for the shed. 540 watts. Ignore the tiny panel on right haha. System is already charging. Working on video day and night so more updates to come soonIMG_20191013_085344.jpg
 
Oh yes. Lots of shade. So sad. But I have 5 solid hours of sunshine that I calculated in this spot. I had to take a panel off because of this. and the sun just rose, so no sun yet
 
Not really haha it's test array but damn, it is strong enough to be permanent. I have 1000 pound rated ground screws and 500 pound concrete anchors in the wall.

I dig the panel on the flatbed garden cart. I could use a little portable water pumping setup. That would do the trick. Plenty of room for the other components, and they'd be shaded.
 
No way!! I was told I need it for this environment. Dang it. What do you prefer instead?
Certainly don’t need the poly in NV...

Best practice is foam seal all cracks and seams, to prevent ANY air movement through the insulation, then loose set the batts, and tape all staple holes.

a nice tight sealed wall, with batts setup full depth, no gaps, no compressed patches.
 
System is up and running. Step down converter, heater pads for 4.8kwh of LiFePO4. Ac panel and 240v receptacle to charge my Tesla. Still need to make it pretty but everything is grounded and bonded now. Security camera so I can monitor it from anywhwre. Heater system controlled by my phone working. Works great. Insane power

I am so tired. I need to insulate the rafters and add an air conditioner. Need a 240v extension cable to charge my tesla with it.
 
Will are you using the 240v version of the MPPT inverter/charger? and is that why you need the step down converter?

Could you provide some detail on the phone controlled heating system?
 
An overhang to provide shade around the building perimeter, (kind of like a wide brimmed sun hat), would help keep the heat down.
 
I’m doing the same thing in Arizona where we have 320 days of sunshine. I have a 10x12 shed with r19 and r30 rating insulation to help with the 115 degree summers. I’ll have a window mounted AC unit to help in the dead of summer.

Here are my questions for the group. I’ll be installing two Panasonic 335 watt HIT panels (specs here: https://a1solarstore.com/panasonic-hit-335w-solar-panel.html) and I want to do a 24 volt system using two battleborn 100ah lithium batteries I series. With this, configuration, what charge controller and inverter should I use?

I’d like to use Victron 100-30 charge controller or this all in one MPP system found on Will’s site: https://www.mobile-solarpower.com/all-in-one-solar-power-packages1.html

What is the advice of the group?

Thanks!

John
