Smart battery monitoring for lithium and high-voltage systems
The Victron Energy advanced battery capacity monitor is specifically designed for high-voltage, lithium-based energy storage systems.
It provides an accurate picture of the battery's state of charge, voltage, charge and discharge current, and remaining runtime.
This smart battery monitor is an ideal choice for solar systems, RVs, boats, off-grid and backup power solutions.
Why is battery monitoring important?
The reliability of the energy storage system greatly depends on the state of the battery.
Monitoring based solely on voltage measurement can often be misleading, especially for lithium batteries.
With this advanced battery monitor, you can accurately track:
- the current state of charge (SoC)
- the amount of energy consumed and delivered (Ah, Wh)
- the instantaneous charge and discharge current
- the voltage in the system
- the estimated remaining runtime
Continuous monitoring contributes to extending battery life, avoiding overcharging and deep discharging, and ensuring more efficient operation of the entire energy system.
Main features and functions
- Monitoring of high-voltage battery packs
- Bluetooth connection with smartphones and tablets
- Real-time consumption measurement and energy balance
- Adjustable alarms for low or high voltage, SoC level, and current
- Programmable relay output for controlling external devices
- Easy configuration via mobile app
- Data logging and detailed graphs for energy system analysis
Bluetooth and smartphone control
The built-in Bluetooth module allows you to monitor the system status directly from your phone or tablet.
With the Victron Connect app, you can easily view:
- the current consumption data (W, A, V)
- the battery's state of charge in percentage
- daily, weekly, or monthly energy consumption statistics
- previous voltage and current values in graphical form
Wireless communication greatly simplifies setup and maintenance, as there is no need to access the device directly: all important functions are available within the app.
Accurate measurement and calibratable parameters
Using a high-precision shunt, the system can measure every single ampere-hour flowing in and out of the battery in detail.
This precise measurement provides the following advantages:
- Realistic battery capacity display even under varying loads
- Tracking of wear: monitoring of decreasing actual capacity
- Reliable remaining runtime calculation
- Battery protection: alerts in time if the state of charge drops to critical levels
Many parameters of the meter can be freely configured, such as:
- Nominal battery capacity (Ah)
- Threshold values for saturation voltage and charge current
- Peukert exponent and charging efficiency
- Alarm levels (voltage, SoC, current)
Alarm and protection for the battery
The built-in alarm functions help prevent battery damage.
The device monitors critical parameters and allows intervention before a more serious problem occurs:
- Low voltage alarm – protection against deep discharge
- High voltage alarm – preventing overcharging
- Programmable SoC levels – setting optimal operating range
- Relay output – automatic disconnection of inverter, charger, or other loads
This way, the entire energy system can be operated more safely and with a longer lifespan.
Ideal choice for solar systems and off-grid operation
In modern solar energy supply systems, the battery is the most expensive and critical component.
With smart monitoring:
- energy storage and usage can be optimized
- it is easy to check how much the solar panel produces and how much the system consumes
- the stability of off-grid operation can be well monitored
- oversized or undersized battery packs can be detected in time
The device can also be excellently integrated into the battery monitoring of RVs, motorhomes, boats, mobile power supply units, and emergency backup systems.
Integration with Victron systems
The product works seamlessly with other Victron Energy devices, such as:
- inverters and inverter chargers
- solar MPPT charge controllers
- DC distribution and monitoring modules
- mixed energy management systems
Thanks to common communication protocols, a single integrated, transparent energy management system can be built, in which the battery monitor plays a key role.
Easy installation and commissioning
The steps for installation and setup can be easily performed even with average technical skills:
- Installing the included shunt in the battery's negative branch
- Connecting the measuring unit to the shunt
- Setting the nominal capacity and basic parameters of the battery
- Bluetooth pairing and fine-tuning via the mobile app
The well-structured menu system and graphical interface make it easy to use even for less experienced users.
Who is it recommended for?
This advanced battery monitoring solution is especially recommended for those who:
- operate a solar system at home, in a holiday home, or a weekend house
- travel with an RV or boat and want reliable onboard power supply
- use off-grid or hybrid energy systems
- want to accurately monitor the state of their lithium battery pack
- consider energy efficiency and long battery life important
Benefits in brief
- Accurate and reliable battery monitoring
- Bluetooth-based, convenient control and data display
- Comprehensive protection and alarm functions
- Easy integration into existing Victron energy systems
- Using it reduces the risk of battery failure
- Facilitates the optimization of energy storage and usage
If you are looking for a reliable, smart battery monitoring solution for your high-voltage or lithium-based energy system, this device makes energy storage transparent and manageable.
