    Cerbo Monitoring Bundle – Inc. Ruuvi Tags & Water Level Sensor

    The Cerbo GX allows you to monitor your entire system. The bundle includes a water level sender and RuuviTags to monitor tank water level plus indoor and outdoor temperature and humidity, along with any other electrical components within your system. Simply connect through the Victron Remote Management (VRM) portal, or access directly, using a GX 5 inch or 7 inch touch screen. You can view our very own campervans Cerbo system overview here.

    What’s included in the bundle?

    • Cerbo GX
    • Water tank level sensor (multiple lengths available)
    • RuuviTag Pro 3 in 1 for outdoor temperature, humidity and motion sensing
    • RuuviTag 4 in 1 for indoor temperature, humidity, motion and air pressure sensing
    • 5 inch or 7 inch touch screen (optional)

    Ensure you purchase the required VE.Direct and VE.Bus cables required to connect any Victron Energy components to your Cerbo. If you need to monitor any additional water tanks (such as grey water tank), you can also purchase additional water tank level sensors.

    Water tank level sensor

    The included water tank sender allows you to accurately measure the exact amount of liquid left in any tank. The sensor utilises a plastic bob which floats in the water to give you an accurate tank level measurement.

    RuuviTag temperature & humidity sensor

    The bundle includes a RuuviTag and a RuuviTag Pro. These temperature, humidity and air pressure sensors allow you to monitor the temperature inside and outside your campervan, boat or house. The RuuviTags are Bluetooth enabled which makes them extremely easy to connect to the Cerbo GX.

    Perfect monitoring & control

    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 challenges remotely. The Cerbo GX turns any power challenge into an effortless experience.

    Maximise your system performance

    The Cerbo GX maximises the performance of your system’s components in real-time and keeps them in perfect tune. With its Dual-Core Processor and the addition of an extra CAN-bus port you can now support even bigger systems; closely follow managed (lithium) batteries while the second port can support up to 25 simultaneously connected VE.Can solar chargers. Four tank and four temperature ports as well as 3 VE.Direct ports, 3 USB ports, 4 digital inputs and 2 relays allow you to expand control to a new level. Maximising systems performance was never this easy.

    GX Touch screen full colour display

    The new GX Touch display allows you to have an instant overview of your system and adjust settings in the blink of an eye. Its super-slim 5-inch waterproof design, top-mountable setup and its simple installation bring a lot of flexibility when creating a crisp and clean dashboard.

    Choose to include a GX Touch display with your Cerbo monitoring system, or alternatively simply monitor your system from your smart phone.

    Simple mounting and configuration

    The Cerbo GX is now optimised to more than meet the standards of installer professionals. The device is easily mountable on a DIN-Rail when combined with the wall mount, and its separate touch screen can now be bolted on top of a dashboard, eliminating the need to create perfect cut-outs. Its new Bluetooth feature enables a quick connection and configuration via the VictronConnect App.

    How to install the Cerbo GX

Check out our Cerbo GX article which explains exactly how to install and wire up water sensors, temperature sensors and other Victron components. It even covers how to connect an LPG tank to the Cerbo so you can monitor LPG tank levels too.
