Sure. I made my own cable by cutting open a standard CAT5 UTP cable and rerouting the wires to match the table in the VE.Can to CAN-bus BMS cables manual https://www.victronenergy.com/live/battery_compatibility:can-bus_bms-cable I will make a new cable at some point to clean it up, but it works...

Thanks for the idea. I'm running the release candidate GUI, so it's a little different path. I found the setting under Services>VE.Can Port>CAN-bus profile. It was set to VE.Can & CAN-bus BMS (250 kbit/s). I changed it to CAN-bus BMS (500kbit/s) and it sprang to life.

I'll try tying pin 2 to pin 6 on the battery side. That would cover both cases. Do you know what the baud rate is for the Cerbo? The hub is set to 9600, but there are other options.

I used the Type A pinout. That's the one that EG4 sells for Victron. I'm too impatient to wait for a custom cable ;-)

I have a EG4 Communications Hub that I'm trying to get to communicate with Victron can bus. The hub is talking to the LiFePower4 battery just fine using RS485, but I can't get the battery/hub to show up in the Cerbo GX device list. The hub is set to Victron CAN protocol, and the hub is connected...

How do the 6000XP modes correlate to the 6500EX modes? I used SUB mode with my EX, where the priority was explicit. Can the XP be set up to operate this way, and how do you do it?

Not complex in terms of setting it up... complex in terms of more points of failure. I guess adding ESS Assistant doesn't make the system more prone to failure, unless it would be a software failure. BTW, have you noticed any improvement in MPPT performance with the Victron system, like...

I exchanged a number of emails with Jason at Current Connected, and he believes I should be able to make this all work with the 5KVA if I have a Cerbo and use ESS Assistant. It's a little complex for my taste, since I'm a proponent of KISS, but it could be doable as long as everything is...

I settled on one 5kVA battery since I was mainly looking for a big UPS. It gives me hours of time to fire up the generator during an outage, even without solar. Adding the panels makes it UPS-plus. Great suggestion about SA. I already have a SmartShunt tied into it... that's where the battery...

Running an experiment today. I changed the 6500 to SBU and set the battery limits as 54V / 51V. 51V the highest "voltage point back to source" allowed in setup. I really would prefer about 53V... which I believe is something like 75-80% SOC. I have a EG4 battery, but the BMS comms does not work...

The more I think about it, the more concerned I am that the Victron would work in my case without constantly having to adjust the battery settings depending on season, weather, etc. The way the EG4 works, and I suspect the other Voltronics based units as well, is that they can differentiate...

I agree totally about not wanting to use any more grid than necessary. Unfortunately, I'm restricted by external factors to a small amount of solar. But I don't want to be totally at the mercy of a generator, either, and I want to avoid the generator for all but long outages. We seem to be...

What makes me question this is that the battery is at 100% SOC in the morning when the PV kicks in, having been recharged from the day before from the grid. If the battery is fully charged, how can the PV charge the battery? It sure looks like the PV is powering the load when you look at the...

Whenever the PV voltage exceeds the 90V MPPT threshold, the battery starts delivering 34W, and the MPPT power appears to reduce the grid consumption. This is apparent in Solar Assistant, as well as my independent Emporia energy monitor. The discharge happens while the inverter is augmenting the...

I don't know if you ever used SUB with your 6500... probably not, but according to my Solar Assistant, whenever there is solar, almost all of it goes to reducing the grid consumption, except for a constant 35W from the battery. During this time, the battery discharges about 5%, after which it...
