Dear Client, A boat power system should not be sized like a small off-grid cabin. On water, the design has to respect DC voltage drop, battery autonomy, marine grounding, fuse placement, inverter surge loads, and the fact that refrigeration and lighting must keep working reliably. I can help you create a practical 12V marine power design that you can actually build from. My deliverables would include: ✅ load schedule for lights, receptacles, refrigeration and inverter loads ✅ solar + wind charge-controller sizing ✅ battery bank sizing based on real daily usage ✅ bus bar, fuse/breaker and wire-size plan ✅ basic electrical layout showing source, storage, distribution and loads ✅ notes for safe installation and future expansion I would especially focus on wire sizing and protection because those are the parts that usually decide whether a boat system stays safe and dependable. A couple of details I would confirm first: 1. Is this a 12V-only boat, or will any AC loads run through the inverter? 2. How many hours per day should the refrigerator run without solar/wind input? If you send the boat size, expected loads and available panel/wind space, I can turn it into a clean design package. Best regards, Prat PCB Must Innovations
