This is a centralized management system designed for boats equipped with three engines. It replaces traditional mechanical switches by consolidating battery switching, emergency paralleling, and monitoring in a single smart unit.

This hub is designed to support high loads. It handles a continuous current of 300 A, an intermittent current of 700 A, and starting peaks (cranking) up to 1450 A.

Yes, the housing is IPX7 certified, ensuring excellent waterproofing. It is also ignition-protected (ISO8846/SAEJ1171 standards), allowing safe installation in engine compartments.

For the house battery (servitude), the hub monitors voltage, consumed current, and overall state of charge (SoC) using an internal precision shunt. For engine starter batteries, monitoring is limited to voltage.

Yes, for safety and maintenance reasons, the hub has a full mechanical backup control for each channel. This allows manual forcing of battery activation or disconnection when required.

The hub measures 363.5 mm in width, 275.4 mm in height and 159.5 mm in depth. Its total weight is 8.4 kg.

Yes, the system includes an emergency parallel connection function. This allows coupling battery banks to ensure engine starting, even if one of the starter batteries is discharged.

The hub uses bidirectional voltage-sensitive switches (VSS). They automatically prioritize battery charging based on configurable activation and cutoff voltage thresholds according to your installation.

Yes, it natively communicates over NMEA 2000 networks via a standard Micro-C port (1 LEN). This allows voltage, current, and charge state data to be transmitted directly to the boat's multifunction displays.

Yes. The hub automatically detects the system voltage and is fully compatible with 12V or 24V installations.

Yes, it natively integrates with the CZone ecosystem. It can be used in standalone mode or activated for the CZone network via the internal DIP switches.

No. Although the hub accepts both voltages, all batteries connected to the system must have the same nominal voltage (either all 12V or all 24V).

The hub is compatible with standard flooded lead-acid batteries and AGM batteries. The battery type is easily configured using the DIP switches located inside the device.

In standalone mode, configuration is done via DIP switch number 2. Different combinations of these small switches allow you to set the battery type (Lead-Acid or AGM) and its capacity in ampere-hours (Ah).

No, the SBH hub already includes an internal high-precision shunt. There is no need for complex wiring or additional components to monitor the service battery consumption.

It must be mounted on a structural bulkhead strong enough to support its 8.4 kg weight, as well as the tension from the large battery cables (up to 50-70 mm²). Ensure the location is also protected from excessive vibration.

The LED indicators provide diagnostic feedback:

Solid red: The switch is in manual mode (override).1 red blink: Module not configured.2 red blinks: Configuration conflict.3 red blinks: DIP switch conflict.
