Victron Energy DC Electrical System Wiring Diagram
System Overview
This document presents a detailed wiring diagram for a DC electrical system, commonly found in marine or recreational vehicle applications. It illustrates the interconnection of various Victron Energy components to create a robust and efficient power management system.
Key Components
- Battery Banks: Includes dedicated banks for Thrusters, Service, and a Starter Battery, typically AGM Super Cycle Batteries (e.g., Victron Energy BLUE POWER AGM 12-125).
- Charging Systems:
- MPPT Solar Charge Controller (e.g., Victron Energy SmartSolar MPPT 100/30): Connects a PV Array to charge batteries.
- IP43 Smart Charger (e.g., Victron Energy Smart Charger 12V-50A): Provides multi-output battery charging, potentially from an alternator or shore power.
- Alternator (e.g., 12V-80A): Connects to the engine system to charge batteries.
- Power Conversion:
- Inverter (e.g., Victron Energy Inverter 12V-800W): Converts DC battery power to AC power for onboard appliances.
- Battery Management:
- BMV-712 SMART Battery Monitor: For monitoring battery state, voltage, current, and power.
- Smart Battery Sense: Wireless battery voltage and temperature sensor.
- Battery Isolation:
- ArgoFet Battery Isolator: Manages charging between battery banks, preventing discharge of one bank by another.
- Distribution and Control: Main switches, DC distribution panels (for Thruster, Engine, Service), fuses (e.g., ANL fuses, MEGA fuses), and circuit breakers.
- Ancillary Components: Bow Thruster system (e.g., Side-Power SE40/125S).
System Interconnections (Conceptual)
The diagram shows how the Thruster, Service, and Starter batteries are connected via main switches and distribution panels. The ArgoFet Battery Isolator facilitates charging from the alternator and potentially other sources to the respective battery banks. The MPPT charge controller connects the solar array to the battery system. The IP43 Smart Charger also connects to the batteries for charging. The Inverter draws power from the battery bank and provides AC output. The BMV-712 Smart Battery Monitor is connected via a shunt to measure current flow and monitor battery status.
Recommendations and Warnings
The document provides recommendations for DC cable and fuse sizing for the Smart Charger and Inverter based on cable length and current ratings. It also specifies AC shore power protection requirements, typically a 16A MCB/RCD circuit breaker for the input.
⚠️ WARNING: 230 VOLT IS EXTREMELY HAZARDOUS. DO NOT TOUCH ANY LIVE WIRED PARTS OF THE INSTALLATION! WHEN IN DOUBT, ALWAYS CONSULT YOUR VICTRON DEALER!
