Hi
Building a Solar System Consisting of
24 Panels 6 x 96v strings Southern Australia North & West Facing
2x 250/100 solar controllers
BMV 702
Multiplus 5000/240
CCGX,I have? or go VenusGX OctoGX for VE connections
My Question is how to parallel them correctly (presuming both Battery direct connection ? ) and provide ccgx connection of VE Direct including a BMV
& max length of VE Direct cables for fault free operation
Hi Wolf. You can parallel your mppt dc outputs to your batts anyway you like, subject to good wiring practice and your need for breakers/fuses/isolators. Victron's and other aftermarket kit may make that simpler & tidier.
The VE,Direct comms can be converted to usb if you run out of ports, with a Victron adaptor on the orphaned one or more. Even a usb hub within limits. So any GX box would do for your kit. There's also VE.Bus to the Multi to consider, but no big deal.
Cable distance a little vague, but maybe 3-5 metres, a bit like usb itself. But an ethernet/wifi connection to the GX eliminates that need over longer distances, with a laptop or suchlike on the end for full access.
Many thanks JohnC
Confirmed my thoughts
VE direct to USB great thanks keeping my CCGX

Keeping up with Off Grid Systems & Reality
Yeh Martin, keep your CCGX. I'm not so sure Victron would recommend long comm wires, and I'd avoid them personally. Up to you if you want to try..
That 'Reality' for me is having a CCGX screen close to the actual kit, so if troubleshooting (ha, never seems to be needed) I've local access. I keep a laptop on the coffee table, and access both the CCGX screen and VRM portal via ethernet/wifi. 2 browser tabs for those. Laid back on a recliner lounge, bluetooth mouse on my knee. Life was meant to be easy, well it was for me.. :)
Decadence would be pushing it to the big tv, but I've avoided that so far..
Yes JohnC
I will give it a go as 2 buildings 20 meters apart & would save Re cabling for Solar
Will let you know
I would prefer your scenario close to the equipment but not always possible
I check VRM portal (Permanently on Tabs )each morning & evening & Even when overseas as I have got to the stage I trust what the Victron gear is doing & telling me from the graphs
55" tv Displaying your data awesome! But better things to do
