Victron Cerbo GX MK3

Victron Cerbo GX MK3

Victron Cerbo GX MK3 The communication center of a Victron installation: inverter/chargers, charge controllers, shunts, batteries with battery management systems, and supported third-party equipment come together here. Monitoring and control are performed via the VRM Portal, a separate display, an MFD, or the VictronConnect app, even without an internet connection via the local network. Difference from the MK2 The Cerbo MK3 is equipped with a faster chipset than the Cerbo MK2, making it suitable for installations where a lot of Victron equipment communicates with the Cerbo. Supply voltage 8 to 70 V DC The device operates on a DC power supply of 8 to 70 V, making it suitable for 12, 24, and 48 V battery banks. The included power cable features an inline slow-release fuse of 3.15 A. The two potential-free relay contacts switch 6 A up to 30 VDC, 1 A up to 70 VDC, or 6 A at 125 VAC. Connectable to Victron and non-Victron equipment. Three isolated VE.Direct ports accommodate a total of up to 15 devices, such as MPPT charge controllers and shunts. VE.Bus runs via two parallel-connected RJ45 sockets for inverter/chargers, including multi-device setups. Two VE.Can ports connect CAN bus equipment; the profile can be selected per port, including VE.Can 250 kbit/s, CAN-bus BMS LV 500 kbit/s, RV-C, and NMEA 2000. Construction and housing. The housing measures 78 x 154 x 48 mm and has an IP20 protection rating, intended for a dry and low-dust setup. Operating temperature -20 to +50 °C. VE.Can 1 is isolated, VE.Can 2 is not; take this into account in the grounding plan. Wall or DIN rail mounting. Mounting is possible on a wall or on a 35 mm DIN rail using the separately available Victron DIN35 rail adapter small (2pcs) (https://shop.top.systems/monitoring-controle/bedieningspanelen/victron-din35-railadapter-small-2st.html), ADA500100100. There is no screen included; the GX Touch screen is connected to the HDMI and USB ports with a single cable. The USB ports provide limited power; use a powered USB hub for consumers. Q&A Q&A Q&A How many VE.Direct devices can I connect? A maximum of 25, distributed across the three VE.Direct ports. Is a screen included? No. The GX Touch 50 or GX Touch 70 screen is sold separately and is connected with a single cable. What voltage does the device operate on? 8 to 70 V DC. The included power cable features a 3.15 A slow-burning fuse. Can I connect a 500 kbit/s CAN bus BMS? Yes. You configure a profile for each VE.Can port, including CAN bus BMS LV at 500 kbit/s alongside VE.Can at 250 kbit/s. Are both VE.Can ports isolated? No. VE.Can 1 is isolated, VE.Can 2 is not isolated. Which microSD card can I use? A card of up to 32 GB. Does it work without an internet connection? Yes. The Remote Console remains accessible via the local network or the built-in Wi-Fi access point. The VRM Portal does require an internet connection. Can I power USB devices directly? Limited. The USB ports provide little power; Victron recommends a powered USB hub. Can it be mounted on a DIN rail? Yes, on a 35 mm DIN rail using the separate DIN35 rail adapter small, ADA500100100. Communication and monitoring are provided by Ethernet 10/100 RJ45, 2.4 GHz Wi-Fi with an access point, and Bluetooth. You can operate the installation remotely via the VRM Portal – Victron Energy (https://vrm.victronenergy.com/login) using the Remote Console, including settings and firmware updates. Also available are Modbus-TCP and MQTT for integration with external systems, a marine MFD app, NMEA 2000, RV-C, and Node-RED via Venus OS Large. Four resistive tank inputs, four temperature inputs, and four digital inputs with pulse counting enable measurement and switching within the same overview.
