Glubux's Powerwall
Exactly, they never get warm, but with a 16 000w peak inverter, big busbars are welcome!

Hi Glubux
Wow you are setting the benchmark very high! Well done.

Just wondering where you get your 90degree battery terminals and bolts and nuts from? I looked for them in our local electrical wholesaler, I could not find them.

Thank you Rad, I got my parts online, on french websites and also Ebay.

Search for "angled terminals" (mine are 50mm²), flange nut and grub screws, I'm sure you can find the same in Australia Wink

Hi Glubux's ,
Your project looks really nice, and now I'm thinking to start my own.

Could you please share your experience on how your power wall runs :
- total power of the solar panel, and where you are located in france (south or north will make a difference!)
- total time to charge the power wall
- longuest period without using EDF electicity
- have you faced any legal issue here in france ?
- is your goal to be totally disconnected from grid ?

I'm not quite ready to start a project like that, but I like to plan things in advance.

Hello, thanks for the compliment Smile

I have 3kw of solar panels, it's hard to say how much time to charge the powerwall because it has never been empty, today was the lowest SOC ever at 55% (since may).
My record is 16 kWh in one day so it would take 2 summer sunny days to fill the  28kWh.
I live in the middle of France, some say we get 1100 hours of sun per year here.
I haven't  faced any legal issues, I'm trying to be totally deconnected from the grid, I'm 100% offgrid since may, I'll see in a few months (winter is coming...)

Good luck with your project.

Absolutely amazing! Glad to hear that you are able to go off grid, some day that dream will become reality for me.  Big Grin

I get plenty of ideas watching you. Thanks Simon for the inspiration. Wonder in the winter what are the temperatures in that place and how they are affecting your system. Please can you share?

Very nice shed

Thanks Smile
I'm working on a heated enlosure for the packs to protect them from low temp, I'll post an update in a few weeks.

I'd just insulate and Run a light bulb when it gets cold Slow heat works well as long as it's sealed up. But Lithium can be used fine in lower temperatures just me mindfuul that high discharges in extreme cold can harm the batteries. In the world of power walls we are talking about super low drain and charge (per cell) that it's really a non issue. I run mine in the winter with zero loss of power or capacity where we get -50 C. I find the batteries will self warm when discharging at higher rates and any information out there on freezeing issues has been from high draw applications
