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...

Thanks for your response. I have seen your videos, but I'm still not sure if I can do what I would like. In the video, it appears that you can emulate the SBU functionality of the EG4, but can you emulate the SUB functionality? Does the inverter know from the MPPT comms when there is solar, or...

I have an EG4 6500EX-48 and want to replace it with a Victron Multiplus II 5kVA, but I want it to work the same way. I mainly use the EG4 for grid backup, but have a small amount of solar and use it to augment the grid. Unfortunately, the idle consumption of the EG4 eats up most of the power...

Yes, I power cycled and let it sit. The unit is only a couple months old, and I was able to adjust the settings when I first installed it. The cable is a direct USB type A male to serial RJ45, and shows up in Device Manager as FTDI. It came with the inverter. It was labeled “EG4 Firmware Cable...

I have a new problem with my 6500EX-48. I can no longer enter User Settings. If I hold the ESC button down for 3 seconds, it enters the settings mode, but then displays a fault triangle warning and a red fault indicator. No fault code is displayed. I can go back to other functions, but I can't...

Thanks. That helps. Does that mean that when there is PV available, the ATS switches to inverter, and the inverter draws what it can from the PV first, then negotiates with the battery for the remaining overage/underage? Does the grid keep charging the battery at the same time if needed? In your...

I suspect it has to do with the biasing of the FETs or something. Maybe the premium brands use some kind of dynamic biasing or something. Or maybe the massive transformer is just more efficient. I was surprised when watching the unboxing and teardown of Adam DeLay's 5kVA Multiplus how much...

I don't want to cover the loss, I want to largely eliminate it. It's just wasteful. I could keep the inverter off except when the sun is shining, but then I lose UPS capability most of the time, especially at night. And I'm still wasting power when the inverter is on, just not as much. Maybe I'm...

I watched your Victron videos and they answered most of my questions. I guess my main remaining one is how to utilize the PV power before it goes to the battery, as you alluded. Are you referring to Power Control or Power Assist? I'm not sure that they do what I want.

Thanks, Adam. I had followed some of your journey on youtube. Didn't realize that you had dumped the EG4s. Did you post some videos about the change? I would like to discuss your changes further if you don't mind... either on the forum or privately if you prefer.

I am happy with this inverter except for the high idle consumption. I am averaging a bit over 120w. I mainly use this as grid backup. I am limited in my amount of PV for a number of reasons, and on a good day I can just make up for the inverter overhead over a 24 hr period... about 3kW. Most of...

Thanks for the diagram and circuit description RC. Adam DeLay sent me the link to this thread after I "discovered" the high voltages on the PV input lines and got a nasty jolt while wiring my PV disconnect breaker. I scoped the two inputs and found 430Vp-p on one lead and 470Vp-p on the other...

Which video of Wills are you referring to? I have not installed any PV yet, just doing some testing. I am measuring very high voltages on the PV input cables of my EG4 6500EX-48 using a scope... 60 Hz square waves... 430 V peak-to-peak on the black lead and 470V peak-to-peak on the red lead. I...

I would have liked to see an option... I have had issues and they are working on it. Not fixed yet.

I was referring to the wiring of the pins, ie. USB pin 1 to RJ45 pin X USB pin 2 to RJ45 pin Y Etc. I'm pretty sure that this is a custom cable.

Both sides...

I have everything that was supplied except this cable. Does anyone know the pinout of this cable? I have the parts to make my own if I have the pinout.

I looked at my order and it appears that they did add it, but I can't find it. I'll have to look around some more.

I watched this and another video from Signature. I think I have a cabling issue. The cable that the Signature video uses (USB Type A to RJ45) is not one that I received. The comms cables that I received are an RJ45 to DB9 serial cable, A Sabrent USB Type A to DB9 cable, which I connected in...

I definitely have the correct address set on the battery, per the manual. I tried both 0 and 1.

BMS_test_1 is what I see on the Configinfo page when I connect. BMS_test_2 is what I see when I click on the Batinfo tab.
