Enhance your power system with the SC303 – a compact, all-in-one battery monitor designed for accurate, real-time insight into your energy setup. With a built-in 300A shunt and support for multiple sensor types, the SC303 is ideal for marine, RV, and off-grid installations where precision and reliability matter most.

300A High-Precision Shunt
Provides complete battery monitoring, including real-time current flow, voltage, and state of charge – essential for managing inverters, winches, thrusters, and other heavy consumers.

Dual Voltage Inputs
Monitor up to two independent voltage sources, supporting up to 75.0 V each – perfect for tracking battery banks or auxiliary systems.

Tank Level & Temperature Monitoring
Includes two resistance inputs that can be used for either tank level sensors or temperature sensors, offering additional system oversight.

JST Temperature Sensor Socket
A dedicated JST connector allows for quick connection of an external temperature sensor, enabling thermal monitoring of the battery compartment.

Versatile System Integration
Use the SC303 to monitor both load and charge sources such as shore power chargers, solar panels, or generators—while also keeping tabs on tank levels or compartment temperature.

Applications:

  • Inverters

  • Thrusters & winches

  • Solar & shore power charging

  • Generator monitoring

  • Freshwater/greywater tank level sensing

  • Battery compartment temperature tracking

Additional Information:

  • Shunt Capacity: 300A continuous

  • Voltage Inputs: 2 (up to 75.0 V each)

  • Resistance Inputs: 2 (tank level or temperature)

  • Temperature Socket: 1 (JST connector)

  • Height: 8 cm

  • Length: 3 cm

  • Width: 11 cm

Upgrade your battery monitoring experience with the SC303 – delivering reliable, detailed data from a single, space-saving module built for demanding power systems.
