Victron Energy 3-Phase VE.Bus BMS System Wiring Diagram

System Overview

This document outlines the wiring configuration for a 3-phase Victron Energy VE.Bus BMS system. The system integrates multiple Victron components to manage power distribution, battery charging, and solar energy harvesting.

Key Components:

4 x Victron Energy Smart LiFePO4 25.6V-200Ah Batteries
3 x Victron Energy Quattro 5KW/24V/230V AC Inverter/Chargers (Master L1, Follower L2, Follower L3)
Victron Energy VE.Bus BMS
Victron Energy BMV-712 Smart Battery Monitor
Victron Energy Color Control GX
Victron Energy Cyrix Li Charge 230
Victron Energy Argo FET Battery Isolator
Victron Energy MPPT 150/185-Tr Solar Charge Controller
Various Battery Protect units, busbars, and circuit breakers.

Battery Bank Configuration

The system utilizes four 24V 200Ah Smart LiFePO4 batteries connected in parallel to form a robust battery bank. Positive battery cables should be kept at the same length, and similarly, negative battery cables should be kept at the same length to ensure balanced charging and discharging.

The VE.Bus BMS is crucial for managing the lithium battery system. It connects to the Quattro units via VE.Bus UTP cables. The BMS GND is not connected to prevent ground loops, as ground is established through the VE.Bus UTP cable.

Inverter/Charger Setup

Three Victron Quattro 5KW/24V/230V AC inverter/chargers are configured for a 3-phase output. The Quattro units are connected in a master-follower configuration (L1, L2, L3). Proper phase rotation for shore power and generator power is critical for correct 3-phase operation.

Important Notes for Quattro Configuration:

The 3-phase setup programming must be completed using Victron's VE.Bus Quick Configure before loading the VE.Bus BMS assistant into each Quattro.
The VE.Bus BMS assistant must be added to each Quattro using VE.Bus Quick Configure after the 3-phase setup is complete.
AC Out-2: This output is available when AC IN-1 or AC IN-2 has power. It is disconnected during battery operation. AC Out-2 supports up to 50A per phase and is adjustable. An Earth leakage breaker or a combination MCB/RCD is required.
AC Out-1: With PowerAssist, each Quattro can add 5kW to the output load per phase. The maximum sum of input and output current per phase is 100A + 21A = 121A. An Earth leakage breaker or a combination MCB/RCD must be installed on the output.
DC Cable/Fuse Size: Recommendations for DC cable lengths between battery and Quattro connections are provided: 0-5m requires 4 x 50SQmm, and 5-10m requires 4 x 95SQmm. Fuse size should be 1x400A or 2x200A per Quattro.
AC IN-1 & AC IN-2 Cable/Breaker Size: Both inputs must be protected by a circuit breaker rated at 100A max per phase or less, adjusted to fit the size of the connected power source.

Solar Charging

A Victron Energy MPPT 150/185-Tr solar charge controller is used to manage the power from the solar array, charging the battery bank.

Monitoring and Control

The Victron Energy BMV-712 Smart battery monitor provides detailed information about the battery status, including voltage, current, and state of charge. The Victron Energy Color Control GX serves as the central monitoring and control unit for the entire system, connecting to the Quattro units via VE.Bus.

Safety Precautions

WARNING: 230/400 VOLT IS EXTREMELY HAZARDOUS. DO NOT TOUCH ANY LIVE WIRED PARTS OF THE INSTALLATION. WHEN IN DOUBT, ALWAYS CONSULT YOUR VICTRON DEALER.

The Battery Protect unit must be programmed either directly on the device or via a Bluetooth-enabled smartphone or tablet. The load disconnect output of the VE.Bus BMS connects to the Remote H terminal of the Battery Protect.

The BMV shunt is upgraded to 1000A and is mounted directly on both busbars.

Connections

The diagram illustrates various connections including:

VE.Bus connections between Quattro units and to the Color Control GX.
DC connections from batteries to busbars and Quattro units.
AC connections for shore power, generator input, and AC distribution.
Connections for the BMV-712 Smart, Cyrix Li Charge 230, and Argo FET Battery Isolator.
Connections for the starter battery and alternator charging.
