Integrating Behind-the-Meter Solar with Variable Hashrate Scheduling

Using automated telemetry scripts and custom firmware profiles to dynamically ramp computing power to match solar generation curves without degrading hardware longevity.

Australia boasts some of the highest solar irradiance in the world, with rooftop and ground-mount PV installations regularly generating surplus power during midday hours. However, feed-in tariffs across Victoria and regional energy networks have dropped to near-zero or negative rates during peak generation windows.

Behind-the-meter crypto mining allows agricultural properties and rural landowners to monetize otherwise curtailed solar generation directly. Rather than exporting 100kW of solar at 3 cents per kilowatt-hour, operators can consume that power on-site to run mining equipment.

The engineering challenge lies in the intermittent nature of solar output due to passing cloud cover. Frequently toggling ASIC power supplies ON and OFF causes extreme thermal cycling, which rapidly fractures microscopic solder balls beneath BGA chip packages. The correct approach is dynamic hashrate modulation via autotuning firmware APIs.

By querying the solar inverter's Modbus TCP interface every 15 seconds, our custom telemetry scripts dynamically scale miner frequency and voltage profiles between low-power eco modes (50% rated wattage) and maximum turbo modes (110% rated wattage), keeping total grid import at precisely zero while preserving chip thermal stability.
