Pick a starting point for your plan, then customize. Each example loads the same wiring diagram you'll see in the planner — usage, generation, and hardware are already wired up so you can see how the pieces fit together before you change a thing.
Friday-to-Sunday trips — small fridge, single-burner cooking, laptop on the table, diesel heater for shoulder seasons.
Educational estimates only — not a substitute for a licensed electrician. Verify against ABYC E-11 and manufacturer specs before installing. See full disclaimer.
BETA — Educational estimate, not an engineered design.
Verify all wire gauges, fuse and breaker ratings, run lengths, and system sizing against ABYC E-11, manufacturer spec sheets, and a licensed electrician before installing or energizing. Ampacity uses ABYC E-11 single-conductor, free-air, 105 °C-insulation copper (typical marine BC-5W2); resistance is NEC Ch. 9 Table 8 at 75 °C; system is nominal 12 V DC and 120 V AC. Wire rated below 105 °C, ambient-temperature derating, and bundle derating are not applied. No code-compliance review or engineering sign-off is provided or implied.

Anchored in hot regions — heavy 12V AC is the headline load. Solar maxed out, 3-pack bank for multi-day autonomy, large fridge, parked for weeks at a time. Pushes 12V to its real ceiling — anything heavier and you want 24V/48V.
