1. Safety Precautions

1.1 General Safety Precautions

• Read this manual carefully before using the equipment.
• The SmartShunt IP65 is rated IP65 (potted) — it is dust-tight and protected against water jets from any direction.
• The product contains no user-serviceable components. The electronics are permanently potted.
• Ensure correct polarity when connecting; incorrect wiring can damage the unit.
• The pre-wired cables are permanently attached — do not attempt to remove or modify them.

1.2 Battery Safety Warnings

• Batteries can generate explosive hydrogen gas. Keep sparks and flames away.
• Ensure adequate ventilation around batteries.
• In case of contact with battery acid, rinse immediately with plenty of water and seek medical attention.

1.3 Transport and Storage

• Storage temperature: -40°C to +50°C.

2. Product Description

2.1 The Battery Monitor

The SmartShunt IP65 is a weatherproof, all-in-one battery monitor with a potted IP65 enclosure. It measures battery voltage, current, power, consumed amp-hours and state of charge. Unlike the standard SmartShunt (IP21), the IP65 variant is designed for outdoor and harsh-environment installations where moisture, dust, and water exposure are concerns.

The SmartShunt IP65 has built-in Bluetooth, pre-wired cables with ring terminals, and a VE.Direct cable for GX device integration. It is available in 300A, 500A, 1000A, and 2000A variants.

2.2 Pre-wired Cables

• Red cable (Vbatt+): 1.5m with 1A slow-blow fuse and M10 eye terminal
• Grey cable (Aux): 1.5m with 1A slow-blow fuse and M10 eye terminal
• Black cable (VE.Direct): 1.5m with VE.Direct socket

2.3 Accessories

• Temperature sensor (optional, ASS000100000): For battery temperature monitoring via the Aux input.
• VE.Direct Bluetooth Smart Dongle (ASS030536011): Extends Bluetooth range when the built-in signal is insufficient.

4. Installation & Wiring

4.1 What's in the Box

The SmartShunt IP65 unit with pre-wired cables:

• Red cable (Vbatt+) — 1.5m with 1A fuse and M10 eye terminal
• Grey cable (Aux) — 1.5m with 1A fuse and M10 eye terminal
• Black cable (VE.Direct) — 1.5m with VE.Direct socket

4.2 Mounting

The SmartShunt IP65 can be mounted in outdoor or harsh environments. It has two 5.5mm mounting holes in the base. Use appropriate screws or bolts (not included) to secure the unit.

4.3 Connections Overview

4.4 Basic Electrical Connections

1. Connect the negative battery terminal to the M10 bolt on the BATTERY MINUS side. Torque: max 21Nm (300A: 10Nm).
2. Connect the negative of the electrical system to the LOAD MINUS side. Torque: max 21Nm (300A: 10Nm). All DC loads, inverters, battery chargers and solar chargers must connect here.
3. Connect the M10 eye terminal of the red cable (Vbatt+) to the positive battery terminal.

The battery monitor is now powered up.

4.5 Auxiliary Connections (Optional)

The grey Aux cable can monitor one of the following:

• Second Battery Voltage: Connect the M10 lug of the grey Aux cable to the positive of a second battery. The second battery's negative must be connected to the LOAD MINUS side.
• Midpoint Monitoring: Connect the Aux cable to the midpoint of a series battery bank.
• Temperature Monitoring: Connect the optional temperature sensor (sold separately). The sensor ring connects to the negative battery terminal.

4.6 GX Device Connection

Connect the VE.Direct socket (end of the black cable) to a GX device using a standard VE.Direct cable. This provides real-time battery data on the GX device and the VRM online portal.

5. Configuration

Configure the SmartShunt IP65 using the VictronConnect app (Bluetooth or USB via VE.Direct). After making the physical connections, the following essential settings should be configured:

5.1 Essential Settings

5.2 Lithium Battery Settings

For LiFePO4 batteries, set the Peukert exponent to 1.05 and the Charge Efficiency Factor to 99%. Set the Discharge Floor as recommended by your battery manufacturer.

5.3 DC Meter Mode

The SmartShunt IP65 can also be configured as a DC energy meter instead of a battery monitor, measuring DC current and power of a specific device.

6. Troubleshooting

LED Status Codes
