Hello, Bitaxe family. I posted a week or so ago (Meet SolarAxe, All in One Plug and Play Solar Miner : r/BitAxe) to gauge interest in a project I am working on. The response was awesome and I learned a lot about what the community would be interested in. So, thank you!

SolarAxe.co is now live and open to orders. Only 2 versions are currently available, but we are working hard to get the remaining 2 planned products launched, as well as future products planned. Order structure is simple, and safe with Shopify Payment Processing. Currently, orders are done on a reservation system to secure you spot in the production queue and are fully and easily refundable for up to 14 days.

What is SolarAxe? We are a company helping make solar powered mining easy. We currently offer 2 products in our "SolarAxe V-Core" series. V-Core is our 5V power system designed to safely run 5V miners, specifically a Bitaxe 601/602. Simply plug a 100W solar panel using a XT60 adapter into the V-core and plug up to 2 miners into the core. Runtime and extended runtime can be found on the site.

We are excited for this launch and hope our product can help out those who want to skip everything that is needed to setup solar mining.

We know this product is not for everyone, and we know that our products won't work for every miner right at launch. We will be working continuously to add adapter cables for miners that have XT30 or USB-C, as well as adapters for non MC4 solar panels.

Solar Miners Sub Reddit: r/SolarAxe

Hello Bitaxe Fam,

I joined the bitaxe fam about 6 months ago and fell in love with the open source open community feel, as well as the tinkering. I converted 4-5 bitaxe variants to run off 400 W of solar and learned a lot in the process. See my previous setup ... https://www.reddit.com/r/BitAxe/comments/1t00jyw/my_bitaxe_setup_solar/ ... And recently completed my own standalone all-in-one miner concept that has been running for a few weeks now without any issues.

Anyways, I've seen a lot of interest in solar bitaxe mining, so I've created an all in one plug and play solution for up to 2 (5v) bitaxe sized miners.

I'm curious at what kind of GENUINE interest in this product there is so I can make some decisions on the amount of initial investment I put into this. Regardless I already have the manufacturing equipment needed, and I will be producing these and will offer for sale, but if enough interest is shown I may scale sooner to cut down on production lead time.

SolarAxe v1

Deploy Anywhere (near wifi) Panel: $59.99

Power Core $59.99: The plug and Play solution, either using your own 100w panel or a SolarAxe panel. Simply plug the panel into the Power Core, plug the power output into your bitaxe miners, that's it. This system eliminates a PSU by utilizing a battery to dc buck converter system. The system includes a small battery that keeps your miner running stable on partly cloudy days. In addition fuses and voltage delays are in place to only power miner when solar input is adequate and delays power on/offs so your miner only runs when solar input is stable.

SolarAxe v2 will be a 12v version for a NerdQaxe or BitAxeGT but is TBD based on interest.

*TLDR*: I'm wanting to gauge interest in this product so I can decide before launch if I scale my production to cut down on production lead time. Please comment if you are interested and what product.

This is my setup I have been working on for the last couple weeks that lives in my garage in Texas. I love tinkering around. It has been working great, but I already want to add more and build more haha

Solar (seen in the background outside of older setup in last picture)

• 400W of panels
• Renogy Charge Controller
• 500W Inverter
• 12v 100ah battery

Currently I turn the miners off and on via phone app of a smart wifi enabled power strip around 9am from work. They currently only run when I am producing ~200+ watts of solar which is about 9am - 6pm at the moment, and an additional 2 hours on the battery which leaves about 2 remaining which keeps the smart power strip alive and connected through the night. I could push the battery more but I will wait until I add another.

Future state currently in progress is programming logic via Home Assistant that will automatically measure incoming watts, and turn miners on after 5 continuous minutes of power exceeding x amount of watts (200) and then turn off after battery depletes to 60-70%

Case & General Cooling

• laser cut a case
• 2 x 1800 rpm 120mm PC fans for cool air intake
• 2x 3000+ rpm 120mm fans for exhausting hot air through a lasercut/3dPrint window adapter.
• 1x 120mm pc fan on top that blows cool air over the PSU's that are mounted on the back of the case.
• Each miner has a smart plug on a power strip that I can turn on and off from work on my phone.
  • Helps with miners like NerdQaxe++ that struggle to reconnect when power and internet come back on at the same time, quick remote power reset after Internet is back up fixes it

4 Miners ~11-13 TH/s @ 170W-220W (includes 36W from 12v x4 fan power/controller)

• 1x NerdQaxe++ ~6.6-7.4 TH/s, Temps ~58c-60c Asic/VRM
  • Arctic MX-6 thermal paste
  • 120mm front fan for stock asic heatsink , 92mm rear fan, both using 3d printed adapters
  • additional heatsinks on mosfets, vrm, anywhere else that felt hot
• 1x Gamma 801 ~3 TH/s, Temps ~60c-62c Asic, 55c vrm (I struggle to push this further, but I know you can get 4+ TH/s)
  • Arctic MX-6 thermal paste
  • Custom 3d Printed stand
  • Noctua 80mm front fan & stock heatsink, but sanded the black paint off to expose direct aluminum. 60mm rear fan
  • additional heatsinks on mosfets, vrm, anywhere else that felt hot
• 2x Gamma 601, ~1.4-1.7 TH/s, Temps ~58c-60c Asic/VRM
  • Arctic MX-6 thermal paste
  • 1 with Noctua 40mm on stock (sanded down) heatsink, 1 with upgraded heatsink from vendor
  • remix of a dual 3d printed stand each having a 5v 60mm usb fan that I cut and soldered to a splitter
