You can use ve.direct or ve.can if your charger supports it.

ok, thank you for the quick response. I have a charger right now but the charger I have is junk and i'm upgrading my system. I've thought about victron but currently running 12v system and moving to 48v system.

The ve.can allows for daisy chaining a series of sccs together, if you are only going to have one or two then ve direct should be fine.

ok, thank you. My 250/100 didn't come with a ve.direct cable.... errr.... i'll order one. Thank you!

Ve.bus uses standard Ethernet cable so if you have a spare one of those could use that instead of a new ve.direct cable

You'll need to use the ve.can Terminator that came with the GX on the empty ve.bus port if you do use that connection.

Got it up and running thanks everyone
Just got mine today and doesn't detect any solar input. 
Measure 139vdc before I connect PV, then it goes to zero volts when I connect. See a slight spark on PV wire. Unit sees battery and firmware was updated.
Disconnected older BougeRV solar charger, connected Bluetti and nada.

Definitely very strange. Did you get it working?Just got mine today and doesn't detect any solar input.

No, I have not got it to detect PV input. Looks like it is going back to Amazon.

Who was the vendor thru Amazon? What do you mean you plugged it into the bluetti?
sorry, brain fart… Victron thru Amazon. I will get a replacement by Tuesday.

That stinks but saw you are getting a replacement. Good luck. I love my 250/100 but wished I had gone with the 450/100

It's hard to justify paying double the price for the higher voltage capability and other additional features. It does look like you need to go to three strings to get the most of the 250/100 if you have ~40V 400W panels. Before the non RS price reduction it wasn't such a big jump to get to to the rs line.

Most / all of my panels are almost 50voc each. Fun stuff.
