Do you have a diagram of how it's all setup ?

  • 8 panels go to PIP4048MS
  • Removed neo Pixel to reduce light inside the shed (just glows at night)
  • Turned off the light ring in the router

DIYPowerwall Mounting System

This is the mounting system that I came up with to hold my cells. It's both cost-effective & good looking rack mounting system. It makes maintaining and building your battery packs very simple and quick. I've provided as much info here as possible and if you'd like to donate to help pay for all the RnD monies that started this process it would mean a lot. The first one I had made the prototype cost just under $400 AUD and the next 4 costs about that again so was quite expensive to get it all started. My paypal is https://www.paypal.me/homebrewpowerwall. I have 8 left I can sell in stock and are $85 each and available to pick up from Brisbane Australia - I don't post. 

Both Mark & Ivan have generously donated their CAD files below if you would like to build your own. Please also consider a donation to them for their contribution. 

CAD Files 







UPDATED PHOTO of the mount to try making it a little easier to read.  Click This image, then don't forget to hit the 'zoom in' button top right to make it original size



above diagram is straight from the laser cutters, differences in this V5 version is rounded corners where they COULD touch the cells and added 1mm (to that skinny bit at the top below the square bit) to allow for heat shrink to be fitted to reduce the chance of short to ground. 

After months of use, I've successfully tested my mounts with 157 cells rather than 80p packs

Did you ever figure out a decent battery balancer? I know at one time you were looking. Those small ones appear to make a noise and was wondering if you found a better solution.

Secondly, I notice you have a 48v inverter. Does this mean you have these batteries packs in 14 series (3.7v nominal * 14 = 51. 8v) ? I'm thinking 48v is the way to go because if you need, even momentarily, 50 Amps of 120V AC, that would be over 500 Amps at 12V.

Edit:
I see you are doing 14S3P Smile

Awesome, one thing - I haven't delved much into the solar aspect yet. Can you explain what's going on with the way you have the solar panels positive wired to the PCM60X then from the PCM to battery and fused to some input on the PIP? Can you also explain the SHUNT situation you have going on with all the negative wires? Thanks!
