Introduction
I recently installed a small 12 volt DC to 120 volt AC inverter to power a fridge at a customer’s cabin, where they typically use a larger inverter/charger system to power the rest of the cabin. To conserve energy, they shut down the larger inverter when they leave. To address this, we added a small inverter that consumes about five times less power, along with a new set of solar panels dedicated to this inverter. The setup is performing well, maintaining float charge during the day and keeping battery voltage above 12 volts overnight while the fridge runs smoothly.
To enhance this system further, we recently integrated a Victron Cerbo GX, allowing the customer to monitor the setup remotely. With the Cerbo GX, they can access real-time data about their system from anywhere via the internet, ensuring they can check whether the fridge is on or off and how the system is performing overall. This added capability gives them peace of mind, especially as we move into fall and winter, when sun angles change. They only need the fridge during the spring, summer and the fall, typically when they’re away for a week or two, and prefer not to keep the larger inverter on continuously. With the Cerbo GX in place, they can stay connected and informed about their energy usage all year round.
The Cerbo GX is a versatile monitoring and control device from Victron Energy that is commonly used in solar power systems to manage and monitor various components. It serves as a central hub for connecting and managing different Victron products like inverters, charge controllers, and battery monitors, providing real-time data and control over your system.
System Monitoring
- The Cerbo GX provides live data from your solar power system, including battery levels, solar panel performance, energy consumption, and inverter status. It consolidates all of this information into one interface.
- You can monitor the system locally (on-site) or remotely via Victron’s VRM portal (Victron Remote Management), which provides access to real-time data from anywhere with an internet connection.
Control of Devices
- It allows you to control connected Victron devices, such as turning inverters on or off, adjusting charge settings, or even managing load priorities in your system.
- You can optimize the operation of the system to suit specific needs, such as prioritizing battery charging or controlling backup generator operation.
Connectivity and Integration
- The Cerbo GX connects to various components using multiple interfaces, including VE.Direct, VE.Can, VE.Bus, and USB. This allows it to work with Victron inverters, battery monitors, MPPT charge controllers, and more.
- It also integrates with third-party devices such as generators or smart home systems using the relay and digital inputs/outputs.
Remote Control
- Using the VictronConnect app or the VRM online portal, you can remotely monitor and control your entire system, receive notifications, and manage settings from a computer or smartphone.
- This remote functionality is especially useful for off-grid systems or systems in remote locations.
Use Cases for the Cerbo GX
- Off-Grid Solar Systems: Allows detailed monitoring and control, ensuring optimal system performance.
- Hybrid Systems: Manages power from both solar and grid sources, including energy storage, to ensure that your loads are met in the most cost-effective manner.
- Mobile Power Solutions: Used in boats, RVs, and vehicles with solar power and energy storage, providing complete system control.
- Remote Monitoring: Ideal for setups in remote locations where you can’t physically be present to monitor and adjust the system.
Relay Outputs
- The Cerbo GX includes two programmable relay outputs that can be used for various functions:
- Automatic Generator Start (AGS): These relays can control an external generator, allowing it to start automatically when battery levels drop below a certain threshold or based on user-defined settings.
- Load Control: The relays can be programmed to control loads, enabling users to prioritize power distribution or disconnect non-essential loads when battery levels are low.
- Alarm Functions: Users can configure the relays to trigger alarms or notifications based on specific conditions, such as high battery temperature or low voltage.
Conclusion
The Victron Cerbo GX is an excellent tool for anyone who wants complete control and real-time monitoring of their solar energy systems. Its ability to integrate various devices, along with its ease of use and remote management capabilities, makes it a powerful addition to both off-grid and grid-tied systems. Whether you’re managing a residential setup, an RV, a boat, or a remote cabin, the Cerbo GX can help you maximize efficiency and performance.
