Off-Grid System Design

A complete, load-based design for your off-grid power and communications system — so you build the right system once, instead of guessing and overpaying.

Most off-grid systems disappoint because they're designed backward: panel first, load last. We start from your actual energy use and site conditions, then size every component correctly. You get an engineer's design, not a parts list scraped off a forum.

What you receive (delivered as a PDF report in about 5 business days):

• Load-based sizing report — your real daily load worked out, then array, battery, inverter, and charge-controller sizing with the math shown.
• Full bill of materials — every component your system needs, specified by type and rating, so you know exactly what to buy.
• Communications layer plan — a resilient comms design matched to your stakes (satellite internet, LoRa mesh, and HF radio, with honest licensing guidance).
• Wiring & safety overview — the fusing, grounding, and disconnect approach that keeps the system safe and inspection-ready.
• "How to vet and hire an installer" guide — so you can confidently engage a licensed local electrician to execute the build.

This is an educational design and planning service. Off-grid electrical work is subject to local codes and should be installed by a licensed professional. Radio transmission requires licensing in most jurisdictions. Figures are planning estimates.
