The Cerbo-S GX is a communication and monitoring hub for Victron-based solar and battery systems. It gives you remote visibility into your system's state of charge, power flow, and alarms from a phone, tablet, or computer.
The Cerbo-S GX is a Grid Monitoring Node, not an inverter, charger, or battery. It does not generate, convert, or store power — it reads and reports system data from compatible Victron devices over WiFi, Bluetooth, Ethernet, or wired connections. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Critical Power & Interconnection Requirements
- This is a monitoring/communication device — it has no AC output voltage, no continuous or surge power rating, and no PV/MPPT input of its own.
- It does NOT generate, invert, or store electrical power in any form.
- It does NOT have grid sell-back capability.
- Connectivity provided: WiFi (built-in access point), Bluetooth, Ethernet, Micro SD, and USB ports.
- [NEEDS VERIFICATION]: DC input/power supply voltage for the unit itself is not specified in the provided data.
Communication nodes like the Cerbo-S GX are frequently the source of "ghost" fault codes when installers mount them too far from the master inverter/charger or route the RS485/VE.Can cable alongside high-current AC conductors — the induced noise corrupts closed-loop data packets even though the physical connection reads fine. Before closing up the enclosure, verify cable runs with a Digital Multimeter for continuity and keep low-voltage communication cabling separated from AC branch circuits per NEC Article 725 separation requirements for Class 2 circuits. This single step prevents intermittent dropped monitoring data and false battery-communication alarms months after commissioning.

FAQ
Q: Does the Cerbo-S GX generate its own power output or sell power back to the grid?
A: No. The Cerbo-S GX is a monitoring and communication node only. It does not produce, convert, or export any AC or DC power, and it has no grid sell-back capability of its own.
Q: What battery voltage does the Cerbo-S GX require?
A: The manufacturer data provided does not list a DC input voltage requirement for the Cerbo-S GX. [NEEDS VERIFICATION]
Q: Can I connect multiple Victron devices to one Cerbo-S GX?
A: The provided specifications do not detail a maximum device or parallel-stacking count for connected Victron equipment. [NEEDS VERIFICATION]
Q: Is the Cerbo-S GX UL 1741 listed for utility interconnection?
A: No UL 1741, UL 458, or IEEE 1547 listing is provided in the manufacturer data for this device. As a monitoring node, it is not an inverter and is not subject to utility interconnection listings in the same way an inverter is. [NEEDS VERIFICATION]
Q: Does the Cerbo-S GX include a WiFi module?
A: Yes. It has a built-in WiFi access point along with WiFi and Bluetooth connectivity, so no separate WiFi module is needed for wireless monitoring.
