Maz Ocean recommends Victron Battery Smart system:
- Communicate directly, and in the same language, with the entire system, including inverters, chargers, solar charge controllers, BMS, etc.
- Well-respected brand founded in 1975 and a leader in Lithium System designs and integration
- 2-year manufacturer warranty
- Bluetooth connection direct to battery for individual battery monitoring
Each individual cell of a LiFePO4 battery must be protected against over-voltage, under-voltage, and over-temperature. The BMS ensures that ALL of your battery cells are protected.
External vs Internal BMS
Both internal and external BMS will protect your batteries, but there are concrete advantages to an external BMS system.
Internal BMS have the ability to disconnect the battery from the system to protect them, but do not have the ability to stop charge and discharge independently, control other equipment, or communicate with the entire system.
External BMS Advantages
- Shut down or disconnect loads in case of imminent cell under voltage.
- Reduce charge current in case of imminent cell overvoltage or over temperature
- Shut down or disconnect battery chargers in case of imminent cell over-voltage or over-temperature.
- Max discharge increase of 330 amps over Internal BMS
- Ability to have multiple inverter/chargers
- Max charge increase of 300 amps over Internal BMS.
Battery System Monitoring
- Slim, waterproof, touchscreen display
Instantly monitor the battery state of charge, power consumption, power harvest from PV, generator, and mains, or check tank levels and temperature measurements. Easily control the shore power input current limit, (auto)start/stop generator(s) or change any setting to optimise the system. Follow up on alerts, perform diagnostic checks and resolve complications remotely.
VRM Portal: Monitor, control and configure the Cerbo GX remotely, over the internet. Just like if you were standing in front of the device, using Remote Console. The same functionality is also available on the local network LAN, or using the WiFi Access Point of the Cerbo GX.
Solar Charge Controllers
- Bluetooth Smart built-in
- Especially in case of a clouded sky, when light intensity is changing continuously, an ultra-fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers and by up to 10% compared to slower
- If partial shading occurs, two or more maximum power points may be present on the power-voltage curve.
- Conventional MPPTs tend to lock to a local MPP, which may not be the optimum MPP.
- Outstanding conversion efficiency
- Flexible charge algorithm
- Extensive electronic protection
- Over-temperature protection and power derating when temperature is high.
- Internal temperature sensor
- Will initiate charging even if the battery has been discharged to zero volts.
It’s what we do! Maz Ocean has installed numerous lithium battery systems on a variety of boats ranging from a couple thousand Watt-hours to well over 50,000 Watt-hours.
Just like each battery type has its strengths, so do installers. Some of our strengths include listening to each and every client’s particular use case, needs, and budget considerations. We don’t have a cookie-cutter approach. We design and tailor the system YOU need.
