Victron Energy Power System Wiring Diagram
Overview of a Victron Energy system configuration, detailing component connections and recommended specifications.
System Components
This system integrates various Victron Energy products for comprehensive power management:
- VE.Bus BMS: Battery Management System for Lithium batteries.
- VE.Bus Mains Detector: Detects AC mains presence.
- GX Touch 50: Touchscreen interface for Cerbo GX.
- Cerbo GX: Central monitoring and control hub.
- SmartSolar MPPT 100/30: Solar charge controller.
- PV Array: Photovoltaic solar panels.
- PV Breaker / Isolator: Protection for the solar array.
- BMV-712 SMART: Battery monitor for state of charge and voltage.
- Smart BatteryProtect 100: Protects batteries from over-discharge.
- Lithium Smart LiFePO4 Batteries (2 x 12.8V-100Ah): Main energy storage.
- Starter Battery (12V-100Ah): For engine starting.
- MultiPlus 1600VA/12V DC/230V AC Inverter/Charger: Converts DC to AC and charges batteries.
- Orion-Tr Smart 12/12-30 DC/DC Charger: Charges the starter battery from the main battery bank.
- Alternator (12V-80A): Vehicle's charging system.
- AC Distribution / MCB/RCD: AC power distribution and protection.
- Shore Power Connection: Connection to external AC power sources.
System Connections and Notes
Key wiring considerations and operational notes:
- Battery Cable Lengths: Keep positive battery cables and negative battery cables all at the same length to ensure balanced charging and discharging.
- BMV Shunt Mounting: The BMV shunt is mounted directly on both positive and negative busbars.
- BMS Grounding: The BMS GND is not connected to prevent ground loops; grounding is established through the VE.Bus UTP cable.
- Component Communication: VE.Direct cables connect MPPT and BMV to Cerbo GX. VE.Bus connects MultiPlus to Cerbo GX.
Component Specifics and Recommendations
Victron Energy MultiPlus 1600VA/12V
Function: Inverter/Charger.
Power Assist: Can add 1.3 kW to the output load when needed, with a total input/output current sum of 16A + 5.6A = 21.6A.
AC Output Protection: Requires an Earth leakage breaker or an MCB/RCD on the output. Cable size must be adjusted accordingly.
DC Cable/Fuse Recommendations:
| Cable Length (0-5 m) | Fuse Size |
|---|---|
| 50 sq mm | 200A (Internal Fuse) |
Note: Cable length refers to the total distance between battery connections and MultiPlus connections. Consider other system loads.
AC Input Recommendations:
| Max Breaker Size | Input Current Adjustment |
|---|---|
| 16A max | Adjustable to fit the connected power source size. |
Note: Breaker and cable size for AC IN should be adjusted accordingly.
Victron Energy Orion-Tr Smart 12/12-30
Function: Non-isolated DC/DC charger.
Specifications: Input 8-17V, Output 10-15V, Power 360W (30A).
Connections: Includes connections for battery (B+), ground (GND), output (OUT), and ignition sense (IGNITION).
Protection: Main fuse for Orion input (e.g., 50A or 30A fuse shown).
Lithium Smart LiFePO4 Batteries
Type: 12.8V-100Ah.
Configuration: Two batteries connected in parallel.
BMS Integration: Connected to the VE.Bus BMS via BTV cables.
Starter Battery
Type: 12V-100Ah.
Charging: Charged by the Orion-Tr Smart DC/DC charger and potentially the MultiPlus when in charging mode.
Cerbo GX and GX Touch 50
Function: Central monitoring and control. GX Touch 50 provides the user interface.
Connectivity: Receives data via VE.Bus, VE.Direct, and Ethernet.
SmartSolar MPPT 100/30
Function: Optimizes solar power harvesting.
Connections: Connects to PV Array, Battery, and Cerbo GX via VE.Direct.
BMV-712 SMART
Function: Battery monitoring.
Connections: Connects to the battery bank via shunt and to Cerbo GX via VE.Direct.
Smart BatteryProtect 100
Function: Load disconnect based on voltage or remote control.
Connections: Connects between battery positive and loads, with control signals to BMS/Cerbo.
Safety Warnings
WARNING: 230 VOLT IS EXTREMELY HAZARDOUS
- DO NOT TOUCH ANY LIVE WIRED PARTS OF THE INSTALLATION!
- WHEN IN DOUBT, ALWAYS CONSULT YOUR VICTRON DEALER!
AC Distribution and Shore Power
AC Distribution: Features MCB/RCD units for circuit protection. Includes earth fault indicators.
Shore Power Connection: Designed for connection to 230V shore power. An isolation transformer or galvanic isolator may be required.
