Detailed description

The BEP intelligent triple-engine battery hub (reference 80-716-0031-00) is a centralized management system designed specifically for vessels equipped with three propulsion engines. Combining battery switching, emergency paralleling, and monitoring in a single IPX7-certified enclosure, it replaces traditional mechanical switch clusters. Capable of handling continuous currents of 300 A, intermittent loads of 700 A, and startup peaks reaching 1450 A, it automatically adapts to 12 V or 24 V battery banks.

CZone and NMEA2000 integration

Unlike standard switches from the brand, this hub natively communicates over NMEA2000 and CZone networks via a Micro-C port. It includes an internal precision shunt to monitor voltage, service current, and overall state of charge (SoC). Supplied with a temperature sensor, it optimizes data transmission while maintaining extremely low power consumption, measured at less than 5 mA in standby mode and 92 mA at maximum operation.

Safety and overcurrent warnings

The system integrates bidirectional voltage-sensitive switches (VSS) to automate priority charging while retaining a physical backup mechanical control for each channel. Warning: In accordance with technical bulletin 197381 issued by Navico Group, this specific model is subject to a report regarding an overcurrent issue. It is therefore classified as obsolete material in our catalog and is intended exclusively for replacement in existing installations.

Expert opinion

Pol CONIN

Digital Manager

« Advanced network integration but caution required regarding loads »

The BEP smart battery hub for three engines is theoretically a major advance in simplifying marine wiring by merging heavy-duty power switching and advanced CZone/NMEA2000 monitoring. Its ability to handle 300 A continuously with mechanical backup modes makes it an interesting central component. However, integrating this component today requires great caution: the manufacturer’s official technical bulletin warning of an overcurrent risk significantly limits its use. As installers, we recommend it only as a strict replacement part (retrofit) for existing systems already sized, ensuring that actual loads do not approach the factory-specified limits.

Frequently Asked Questions

Need help? Contact us

What is the BEP triple-motor smart battery hub?

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 into a single smart housing.

What current capacities does this hub handle?

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

Is the SBH hub waterproof for marine use?

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

Which battery data does the hub monitor?

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

Does the BEP battery hub include a manual backup control?

Yes, for safety and maintenance reasons, the hub includes a full mechanical backup control for each channel. This allows manual activation or disconnection of batteries as needed.

What are the dimensions and weight of this triple-motor hub?

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.

Does the SBH hub allow emergency parallel connection of batteries?

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

How does voltage-sensitive switching (VSS) work on this model?

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.

Is this hub compatible with NMEA2000 networks?

Yes, it natively communicates on NMEA2000 networks via a standard Micro-C port (1 LEN). This allows it to transmit voltage, current, and charge state data directly to the boat's multifunction displays.

Can this hub be used on a 24V system?

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

Is the SBH hub compatible with the CZone control system?

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.

Can you mix 12V and 24V batteries on the same hub?

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).

Which battery types are compatible with this smart hub?

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.

How to configure the type and capacity of the service battery?

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 or AGM) and its capacity in ampere-hours (Ah).

Is an external shunt required to monitor the house battery?

No, the SBH hub already includes a high-precision internal shunt. No complex wiring or additional components are required to monitor the house battery consumption.

Where should the battery hub be installed aboard the boat?

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

What do the red flashes on the hub's LED indicators mean?

The LED indicators provide diagnostic information:

Solid red: The switch is in manual mode (override).1 red flash: Module not configured.2 red flashes: Configuration conflict.3 red flashes: Conflict at the DIP switch level.
