Home Data Center Powerwall Build
#1
Thought I would start this thread, primarily to obtain help and guidance in building a grid connected or off-grid power wall... or something in between. I am very new to solar generation and battery storage, so will probably need a lot of help.

The home data center is a personal project I've wanted to create for some time. See the photos below, which show the building stages. The building is finally at lock up stage, so now is a great time to undertake the wiring for the solar panels and battery storage as that will be external to the data center.



 





 

The roof is a skillion design and will probably only support a total of 6 solar panels. I was thinking of using a panel similar to the Trina 295 watt, but am open to ideas on the most cost effective units. I will need a solar panel mounting frame like this Clenergy Solar Frame and will probably need two frames to mount the 6 solar panels. I will also need a stainless steel cabinet of some sort to store the batteries external to the data center.

Anyway, that is my first update. Look forward to hearing your thoughts, ideas, and recommendations.

Hi and welcome

I had to google home data centre  Tongue

Google tells me is a man cave for the internet age   Wink

Looks like an interesting build. I'll be following. I don't have much to offer knowledge wise, as I'm also on the steep learning curve. 

I have a 48v LiFePO4 off grid system running some loads in my man cave.

Cheers

Hey there, sorry for the delay in writing. To be honest I call it a home data center, but man cave would certainly suffice. Not quite sure what it will be when I am finished, but as long as it gives me more space to run my compute loads and experiment then it will be a success in my eyes.

Right now I am doing all the boring stuff, like insulation and internal cladding. Will also wire the electrics for on-grid/off-grid and data. I purchased a used 45RU rack so that can be installed once the floor is completely sealed and the rubber flor tiles laid. Lots to get done. 

Have also been looking at solar panels and mounts, with Trina Honey M Plus 300 watt looking the best given my limited roof space. Have also been looking at panel mounting hardware, based on the roof sloping away from north I'll need a tilt frame that can do 30-60 degrees.

Any ideas, comments, suggestions greatly appreciated.

Well the journey has started. Managed to get my hands on these Radiant panel mounts (6 in total) for $40... need to find the rails that go on top so I can attach the solar panels. No idea if the rails need to be Radiant brand? If anyone knows or can provide some advice that would be great.

Not sure how big these are so I'm not sure the orientation you're mounting it on but it looks like there's clamps on it already that would clamp down on the panels. But yes you can mix and match as long as you can figure out how to put it together. I am using unistrut channels which are readily available at most hardware stores like homedepot and not that expensive. Then i went for unirac end mounts. I searched youtube for lots of tutorial on mounting with these hardware.

The brand of the rails doesn't matter so much in conjunction with the panels; that is, unless there is some really super proprietary edge on the panels. The way you have the one standing up is the correct way to mount the panels onto those. You adjust the clips inside the track to match your panels. It looks to me as if the panels would go horizontal on those rails and not vertical.

In either case, I'd recommend connecting the back part (the right angle end of the triangle) on a hinge of some sort so that you can disconnect the lower end and tip the whole assembly backwards. This will allow you to do cleaning and maybe maintenance if needed easily

Hi Guys,

Thanks for the comments and advice. The Radiant tilt racks still require rails to be attached horizontally, upon which the solar panels are mounted vertically. This picture whilst not a Radiant system shows what I explained above.



I've contacted a Radiant suplier in Melbourne to get a price on the parts I'd need to be able to mount panels. The pricing doesn't look too bad, but since i dont have any panels yet I have time to find cheaper alternatives. 

Hope this helps. I have a long way to go... and am still learning. Not to mention working out how to connect it all together  Smile

Try your local big box hardware store for pricing on aliminium channeling. It might be cheaper to just go that route and and fasten it all down that way.

If only we had those stores in Australia... would be awesome. But thanks for the advice. I'll keep my eyes open for some second hand goods, or if all else fails I'll purchase from the Radiant supplier.

Don't you have a Bunnings Warehouse near you? I think that would be the closest you can get to a home improvement big box store there. seemed they were all over Australia back in 2010, I visited spent three weeks flying and driving across the your fine country.

later floyd
