![]() A latest state of the art DC Current Transformer placed around the conductor with no need to break the connection.Battery monitoring is done using the latest circuitry and software that includes the charge efficiency factor, the battery temperature and Peukerts exponent to calculate the remaining capacity accurately and efficiently. The unit keeps a track of loads and battery condition even when the NMEA2000® network is powered off so the total current draw or battery condition is always maintained and is known when the network is next powered on. It can also measure the voltage and current being drawn by DC loads such as Inverters, refrigerators etc. It also calculates the current state of charge and the battery life remaining at the current rate of discharge. The BM100 system is priced at £270.The Oceanic Systems 3410 DC Monitor accurately measures the DC voltage, the DC current and the attached battery temperature and reports them over the NMEA2000® network. Multiple BM100’s can be installed for each battery bank if required and they can be field programmed to display individually on the NMEA 2000 device. Suitable for 12, 24V and 48V systems, the standard smart shunt is rated at 500A with 1000A and 2000A versions available for larger systems. All Victron solar panel controllers (MPPTs) and battery monitors can now also interconnect to NMEA 2000 via the veKonvert interface which is also available separately. The BM100 is part of a wider group of products now introduced by Digital Yacht which bring NMEA 2000 connectivity to Victron systems using the veKonvert interface. The system utilises Victron’s proprietary VE.Direct data connectivity as a source for the NMEA 2000 data. The product is a collaboration between Victron Energy and Digital Yacht. There’s also an optional battery temperature sensor available. Monitoring the battery with the BM100 will give important feedback to the user so that remedial measures can be taken when necessary. Battery life may be shortened by under-charging, over-charging, excessively deep discharges, excessive charge or discharge currents, and by high ambient temperature. The service life of batteries depends on many factors. We’re increasingly reliant on DC battery electrical power while afloat for lighting, refrigeration, pumps, winches etc so having accurate battery information and monitoring charge from various sources is essential. Alarms and alerts for low capacity and voltage can also be enabled. ![]() Modern MFDs from leading manufacturers such as Garmin, Raymarine, Furuno and Navico allow electrical data to be displayed via their NMEA 2000 interface. The system features a NMEA 2000 interface so your navigation multi-function display can display all key battery parameters. The SmartShunt can also monitor the voltage of a 2 nd battery – typically dedicated to engine starting. ![]() It also keeps track of historical data, such as deepest discharge and average discharge current as well as the number of charge and discharge cycles. Based on these measurements, it intelligently calculates the battery’s state of charge and the time to depletion for the remaining charge. Staring at a black plastic battery enclosure and guessing what’s happening or how long it will last – or watching lights get dimmer, electronics dropping out and a winch not operating? Digital Yacht’s new BM100 battery monitoring system allows for highly accurate DC voltage, current and capacity measurements enabling reliable monitoring of your boat’s battery and electrical system.Ĭore to the system is the SmartShunt.
