I’m new to solar and am installing a hybrid system where I can’t feed any power back to my power company on a split phase 240v USA system
I need to get accurate CT readings from my main to my Cerbo GX MK2 that is about a 125ft away, to control my two Multiplus II output to only what the house is using. I plan to bury ½ pvc and run either Victron CT sensors with extended wires or use a Victron VM-3P75CT which is better?
I am leaning towards the Victron VM-3P75CT from the internet research I’ve done, but do I need an Ethernet switch and what type? Why can’t it plug directly into the Cerbo?
The VM-3P75CT will be installed in my main panel so can I add a two-pole breaker panel to power the Victron VM-3P75CT on it’s own and install the .5amp inline fuse on the neutral since the lines I’m installing the CT’s on are 2awg wire?
You can connect the VM-3P75CT to the Cerbo through the CANbus using an ordinary network cable. This eliminates a switch/router from the mix. Don’t forget to use the CANbus terminators which come with the Cerbo and the meter.
I have no experience with switch/routers, would I need a constant internet connection for this or am I just using it as a switch before the Cerbo GX. I don’t always have internet at the site which is way I wanted to hard wire the VW-3P75CT to the Cerbo. Can this be done using an ethernet cable which I’m told is better that a 125foot CAN cable run.?
Starlink, but I can never send power back to the grid so I need to make sure the connections don’t lose signal which I why I want hard wire with no internet
@psthe4th I recommend you using the VE.Can route. It will be more stable than Ethernet (no external hardware involved) and 125ft are not an issue. However, I would personally opt for a shielded cable to prevent any electromagnetic interference on the way – just to be safe.
