Safety notice
The boundary between what you can build yourself and what must be designed and commissioned professionally.
Last updated September 2026
Self-built compute. Professionally commissioned energy.
You can assemble, configure and operate compute hardware yourself. Solar generation, battery storage, inverters, isolation, earthing, protection and any connection to the grid must be designed, installed and commissioned by suitably qualified professionals in line with local regulations.
No guarantees of supply
Nothing on this site guarantees free energy, continuous off-grid operation, uninterrupted availability, cost savings or financial returns. Generation varies by site, season, weather and shading.
Battery and thermal risk
Battery systems store significant energy and must be sited, ventilated and protected according to the manufacturer's instructions and local rules. Compute hardware adds heat and noise; plan ventilation before installation, not after.
Do not improvise electrical work
Do not modify consumer units, wire generation equipment, or bypass protective devices based on anything you read here. If you are unsure, stop and consult a qualified electrician.
