VE.Direct Hex protocol for RS Smart 48/6000

I have an RS smart 48/6000 (, I want to communicate via the port with a homemade card (AtXmega).
I saw the protocol docs (VE.Direct-BlueSolar-HEX-protocol and VE.Direct-HEX-Protocol-Phoenix-Inverter) but couldn't find the protocol for RS Smart solar...?

Thanks in advance,
Best regards,

Kisae BIC122080 CAN BUS communication with Cerbo GX

Hello! In my camper trailer, I have a Kisae BIC122080 Inverter/Charger that has a CAN BUS port on it (4 pin ATX I believe, manual doesn't specify). I have a Cerbo GX that I would like to connect to the Inverter/Charger if possible. Ideally this would show up similar to the native Victron inverter/chargers being able to show power input from shore power, AC loads powered by the inverter, and charging details for what is going to my battery bank. Does anyone have any idea if this is possible? I believe I would need to create a custom adapter cable to go from the 4 pin ATX CAN BUS connector to the RJ45 CAN BUS connector. I guess my main question is just around the feasibility of the two devices communicating and the Cerbo GX's ability to visualize and integrate the operational data of the Kisae unit. Let me know if there is any other information I can provide! Thanks kindly for reading.

Adding a 3kVa multiplus as a dedicated charger to an existing 5kVa 2 phase system

An existing hybrid system with 2 x 5kVA Multiplus is having grid issues so we are looking at installing a separate Multiplus 3kVa connected to a generator in the charger only mode to charge the battery bank (40kWh LiFe4Po) manually (i.e. switch on the generator when low SoC and no grid). How is this connected to the GX device (Cerbo) in order to monitor?

Is there a way to display Schneider MPPT, Outback MPPT and Morningstar MPPT data on VRM?

I have a client who has an Outback system with 2 x 3kVA Inverters and 1 x 60A Outback, 1 x 60A Schneider and a 45A Morningstar. I want to take out the 2 outback inverters and give him a 10kVA Quattro with Colour Control and BMV. How would i be able to monitor the charge controllers on VRM? Or is it even possible?

No temperature data in serial output?

Hey - I've got a LUA script on a piece of hardware that monitors my SmartSolar MPPT 100/20 and BatterySense.

I swear when I tested it a while ago (previous firmware) I was getting temperature data.

Currently running FW 1.61 and have no temperature (raw serial dump with time stamp) :

023-01-19T08:06:38.088 - SER#1234567890

2023-01-19T08:06:39.097 - FW161

I can see the temperature in Victron Connect.

Anyone able to confirm if this used to work / what happened in v1.61?


EDIT - I re-read the VE.Direct Protocol PDF and see that temperature data isn't one of the fields output on the MPPT units. Can this be a feature request please? Seems an odd field not to have.

250|100-Tr VE.Can MPPT to computer - cables needed?

Hi, as the title suggests, I'm looking to see what cable is used to connect a 250|100 VE.Can smart solar controller to a computer to monitor and control the device. As I understand it this can be done with a VE.Direct cable, and possibly the VE.Can port. So in this case you'd use the VE.Direct--> USB dongle, but I'm not sure how else you could monitor through VE.Can protocol - would that just be standard RJ45 ethernet cable from charge controller --> computer?

Thank you in advance for any assistance.

Victron Pi recent regular loss of communication

I’ve had my system running in a camper for about 2 years. Since the new year I’ve been getting regular loss of communication alarms, whilst parked on my driveway.

In the past the 4G modem (TP link archer mr-600) has been the culprit, but the of thing is the router is still online. In fact the only consistent way of fixing the issue is to reboot the router.

It’s throwing me a bit because the router is still online and showing the Victron pi connected to it.

The router firmware is up to date.

The Victron Pi was running 2.85-large, I’ve just updated this to 2.89, which is the newest available within the unit.

How to stop VictronConnect search for COM ports - Phoenix Inverter Smart?

When software VictronConnect start on Windows, its looking for connected Victron HW connected by VE.Direct to USB interface cable. It will search for some COM port conmnection. OK. Application will find the Inverter, connect it, works as expected. But I have alreaqqdy some other COM port occupied by other HW, especially security devices. In the case application test othert COM ports for possible Victron device, my security device evaluate this test as possible fault of communication and start false allarm. It is done only when application start and I start my connected inverter - so not big issue then. But it means, that it will happen every time the computer will Restart. Just for Inverter it is annoing (no historic data, no VRM connection), OK. But in case I upgrade system for BMV-712 for example, than I have to find the way how NOT let VictronConnect test particular COM ports as mandatory.

Does exist some solution to STOP VictronConnect applicatioon COM port search? Or another way maybee just block particular COM port to be connected by such application?

Thanks for ideas!

Inverter switched off when CANBUS disconnected


I have a Batrium BMS That is connected to the Cerbo gx using the CANBUS. The BMS has a an issue where it freezes for an undetermined amount of time then restarts normally. When it freezes for more than one minute (not sure the exact duration), my inverters turn off. As soon as the CANBUS data is back, the inverters turn on.
Is there a way to program a delay before the inverters turn off?

Extracting Correction Value [%] from CERBO-GX via Modbus TCP


We have Viktron's Cerbo-GX in a PV System, connected to:

- 6 Battery inverters

- 1 Solar Inverter (Fronius)

- 1 Genset

- blueLog XM200 (red below)

Cerbo-GX is purely in charge of power control, being the master of the system, BUT, we are monitoring the system via blueLog-XM200 (Datalogger from Meteocontrol), which is sending the data to VCOM, the monitoring software.

VCOM calculates the system PR (Performance Ratio [%]), which needs to be compensated with the Correction Value [%] from the solar inverter, this is the percentage at which the inverter is operating: 100% if not curtailed, and lower e.g. 50% if operating at half capacity in order to not inject energy in the grid.

blueLog is getting the Cerbo-GX data via the "Mode 2 Register 2700", but the data we are getting does not allow for VCOM to compensate the PR calculation with the Correction Value, basically because we don't get it, but we get a constant Setpoint Value [W] (this is the value given to the grid meter as limit to activate power control preventing to inject PV energy into the grid). We can not compensate PR calculation with this.

Hence my question is:

- Where is the register from which blueLog can get the Correction Value [%] from Cerbo-GX?

This is a value that all controllers send inverters in order to limit their production when needed, to avoid things such as grid fee-din if the site's power demand is too low compared to PV production.

question about MK2/MK3 protocol for setting AcPowerSetPoint / ESS 'Grid Setpoint'

Hi, i am programming some simple functions on top of the MK3 USB interface. I have read the 'Interfacing with VE Bus MK2 protocol' pdf from the site and i have most of the thinks working. My goal is to implement the AcPowerSetPoint via the MK3 interface.

Does anyone know that the correct MK2/MK3 protocol variable is for setting and getting the AcPowerSetPoint? (aka Grid Setpoint)

When i look at 'RAM variables' from the MK2 protocol pdf, i see ID 's 14,15 and 16 and that could be what i am looking for. Unfortunately these ID's don't seem to give the right values.

(Does anyone know the difference between ID 14 and 15? The text is the exactly same for both ID's but they return a different value..)
