Over the past few weeks, I’ve been working on a PLC program. The idea: Two of my Bitaxe miners run continuously. They slightly discharge the battery, which recharges when the sun is shining. Once the battery is full, additional miners are automatically activated to use the surplus solar energy. In parallel, the battery can also be charged from the grid when needed. This grid charging is part of the automation and is triggered by defined threshold values.
I’ve also developed (with a bit of help) a web interface that provides real-time access to key system data: battery status, power production, and miner consumption… Editable fields in blue let you define switching thresholds for each relay. When a relay is active, a green indicator lights up next to it. There’s also a maintenance button that turns on all miners at once. Over the coming weeks, I plan to further improve the layout and expand the functionality.
