Conductor Sizing

Wiring & Conductor Gauge Reference

tinned copper

Conductor selection for the off-grid array and portable-station charging runs. All exposed and marine-adjacent runs use tinned copper to resist corrosion. Gauges below are sized for the listed continuous current with headroom; confirm against your run length and local code before building.

Run Conductor Continuous Current Notes
Panel string → charge controller (PV) 10 AWG tinned copper ≤ 11 A Sized for 3S2P string Isc with margin; UV-rated PV wire outdoors
Controller → battery 8 AWG tinned copper ≤ 30 A Short, fused run; minimize voltage drop
Battery → inverter / station input 6 AWG tinned copper ≤ 50 A Heavy gauge for surge draw; torque lugs to spec
Low-current DC accessories 14 AWG tinned copper ≤ 7 A Sensors, fans, monitoring taps

Overcurrent Protection

Fusing & Disconnect Plan

48V topology

Every source of fault current gets local overcurrent protection sized just above the conductor's continuous rating. A DC-rated disconnect sits between the battery and downstream loads for safe servicing.

Location Device Rating Purpose
PV input DC-rated fuse / breaker 15 A Protects PV conductor; DC-rated for arc interruption
Battery positive Class-T fuse 60 A Main battery protection close to terminal
Battery → loads DC disconnect switch — Isolates system for service
Charge Controller & Safety Checklist

MPPT charge controller configured for a LiFePO4 (LFP) 48V nominal bank. Set the charge profile to LFP — never use a lead-acid profile on lithium.

  • Charge profile: LiFePO4 / LFP. Bulk/absorb and float set per cell manufacturer; no equalization.
  • String matching: 3S2P gives ~67.2 V Voc (winter/spring/fall); 2S3P gives ~44.8 V Voc (summer) — keep within the controller's max PV input voltage at the coldest expected temperature.
  • Polarity & sequence: Connect battery to the controller before the PV array; disconnect PV first when servicing.
  • Tinned copper everywhere exposed to resist corrosion; torque all lugs to spec and re-check after the first heat cycle.
  • Grounding: Bond array frames and the system per local code; verify continuity.
High-current DC caution: A 48V LiFePO4 bank can deliver very high fault current. Always fuse close to the battery terminal, use DC-rated disconnects, and never work on a live bank.
