Waterproof Ingress Protection & Shunt Architecture
The SmartShunt IP65 encapsulates precision current-shunt electronics inside a sealed, waterproof housing. This enables reliable operation in marine bilges, open vehicle chassis, and outdoor battery trailers where exposure to water spray or moisture would damage standard monitors.
The Victron SmartShunt IP65 is an all-in-one waterproof battery monitor (300A / 500A / 1000A / 2000A; Supply Voltage: 6.5 - 70 Vdc, Capacity Range: 1 - 9999 Ah) with integrated monitoring and connectivity stages:
- Main Shunt Terminal: Battery Minus Side, System Minus Side, All Negative Loads, Precision Current.
- Auxiliary Input: 6.5 - 70V Aux In, Starter Battery, Midpoint Voltage, Battery Temp.
- Communications: Bluetooth BLE, VE.Direct, VictronConnect, -40 to +50°C.
Installation Rules & Electrical Connections
- Battery Minus Connection: Bolt the
BATTERY MINUSterminal directly to the negative post of the primary battery bank. - System Minus Connection: Connect all DC loads, chargers, and inverter negative cables strictly to the
SYSTEM MINUSterminal. - Power & Aux Leads: Connect the fused red power wire to battery positive across Supply voltage range 6.5 - 70 Vdc, and route the auxiliary wire across Input voltage range, auxiliary battery 6.5 - 70 Vdc for starter or midpoint sensing.
Auxiliary Sensing & VE.Direct Interfacing
The SmartShunt IP65 provides flexible multi-channel telemetry:
- Auxiliary Input Modes: The user can configure the Auxiliary input Measures voltage of second battery, temperature* or midpoint to track starter battery health, detect cell string drift, or log thermal conditions.
- Broad Capacity Scaling: Accommodates small portable packs up to utility storage banks with Battery capacity (Ah) 1 - 9999 Ah.
- Dual Communications: Wirelessly stream metrics via integrated Bluetooth Smart to VictronConnect, or connect to GX controllers via VE.Direct communication port Yes.
- Thermal Capabilities: Functions without measurement drift across Operating temperature range -40 +50°C (-40 - 120°F) across all SmartShunt IP65 300A / 500A / 1000A / 2000A models.
