Wiring Schematic Description
Below is a textual description of the wiring schematic:
- Shore Power to Surge Protector:
- Shore power inlet (50A) → EMS-HW50C surge protector (6 AWG, L1, L2, N, G).
- Surge Protector to Distribution Panel:
- Surge protector output → AC input of distribution panel (6 AWG).
- Distribution Panel to Inverter:
- AC output from panel (dedicated 30A breaker) → Inverter AC input (10 AWG).
- Inverter AC output → Sub-panel or panel AC bus (10 AWG, 50A breaker).
- Battery to Inverter:
- 48V 100Ah LiFePO4 battery → 100A disconnect switch → 100A Class T fuse → Inverter DC input (2/0 AWG).
- DC-DC Converter:
- Battery → 40A fuse → 48V to 12V DC-DC converter (10 AWG).
- Converter output → DC fuse panel (8 AWG).
- Solar Panels:
- 4 × 400W panels (2S2P) → Combiner box → 30A breaker → Inverter PV input (8 AWG).
- Grounding:
- Battery negative, inverter, DC-DC converter, distribution panel, and surge protector grounded to RV chassis (8 AWG).
- Monitoring:
- Battery monitor shunt on battery negative, connected to display.
